Running \"chain of thought evaluations\" is another use case for extending providers. Doing so follows a similar process as above, where the base provider (such as AzureOpenAI) is subclassed.
For this case, the method generate_score_and_reasons can be used to extract both the score and chain of thought reasons from the LLM response.
To use this method, the prompt used should include the COT_REASONS_TEMPLATE available from the TruLens prompts library (trulens_eval.feedback.prompts).

Following the request to your app, you can then evaluate LLM quality using feedback functions. This is completed in a sequential call to minimize latency for your application, and evaluations will also be logged to your local machine.
To get feedback on the quality of your LLM, you can use any of the provided feedback functions or add your own.
To assess your LLM quality, you can provide the feedback functions to tru.run_feedback() in a list provided to feedback_functions.

In the above example, the feedback function evaluation is done in the same process as the chain evaluation. The alternative approach is the use the provided persistent evaluator started via tru.start_deferred_feedback_evaluator. Then specify the feedback_mode for TruChain as deferred to let the evaluator handle the feedback functions.
For demonstration purposes, we start the evaluator here but it can be started in another process.
"},{"location":"trulens_eval/all_tools/#custom-feedback-functions","title":"\ud83d\udcd3 Custom Feedback Functions\u00b6","text":"
Feedback functions are an extensible framework for evaluating LLMs. You can add your own feedback functions to evaluate the qualities required by your application by updating trulens_eval/feedback.py, or simply creating a new provider class and feedback function in youre notebook. If your contributions would be useful for others, we encourage you to contribute to TruLens!
Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
- Create a new Provider class or locate an existing one that applies to your feedback function. If your feedback function does not rely on a model provider, you can create a standalone class. Add the new feedback function method to your selected class. Your new method can either take a single text (str) as a parameter or both prompt (str) and response (str). It should return a float between 0 (worst) and 1 (best).
"},{"location":"trulens_eval/all_tools/#extending-existing-providers","title":"Extending existing providers.\u00b6","text":"
In addition to calling your own methods, you can also extend stock feedback providers (such as OpenAI, AzureOpenAI, Bedrock) to custom feedback implementations. This can be especially useful for tweaking stock feedback functions, or running custom feedback function prompts while letting TruLens handle the backend LLM provider.
This is done by subclassing the provider you wish to extend, and using the generate_score method that runs the provided prompt with your specified provider, and extracts a float score from 0-1. Your prompt should request the LLM respond on the scale from 0 to 10, then the generate_score method will normalize to 0-1.
See below for example usage:
"},{"location":"trulens_eval/all_tools/#multi-output-feedback-functions","title":"Multi-Output Feedback functions\u00b6","text":"
Trulens also supports multi-output feedback functions. As a typical feedback function will output a float between 0 and 1, multi-output should output a dictionary of output_key to a float between 0 and 1. The feedbacks table will display the feedback with column feedback_name:::outputkey

Bases: App
Recorder for LangChain applications.
This recorder is designed for LangChain apps, providing a way to instrument, log, and evaluate their behavior.
Creating a LangChain RAG application
Consider an example LangChain RAG application. For the complete code example, see LangChain Quickstart.
from langchain import hub\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.schema import StrOutputParser\nfrom langchain_core.runnables import RunnablePassthrough\n\nretriever = vectorstore.as_retriever()\n\nprompt = hub.pull(\"rlm/rag-prompt\")\nllm = ChatOpenAI(model_name=\"gpt-3.5-turbo\", temperature=0)\n\nrag_chain = (\n {\"context\": retriever | format_docs, \"question\": RunnablePassthrough()}\n | prompt\n | llm\n | StrOutputParser()\n)\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Defining a feedback function
from trulens_eval.feedback.provider import OpenAI\nfrom trulens_eval import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens_eval.app import App\ncontext = App.select_context(rag_chain)\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n
The application can be wrapped in a TruChain recorder to provide logging and evaluation upon the application's use.
Using the TruChain recorder
from trulens_eval import TruChain\n\n# Wrap application\ntru_recorder = TruChain(\n chain,\n app_id='Chain1_ChatApplication',\n feedbacks=[f_context_relevance]\n)\n\n# Record application runs\nwith tru_recorder as recording:\n chain(\"What is langchain?\")\n
Further information about LangChain apps can be found on the LangChain Documentation page.

Bases: App
This recorder is the most flexible option for instrumenting an application, and can be used to instrument any custom python class.
Track any custom app using methods decorated with @instrument, or whose methods are instrumented after the fact by instrument.method.
Using the @instrument decorator
from trulens_eval import instrument\n\nclass CustomApp:\n\n def __init__(self):\n self.retriever = CustomRetriever()\n self.llm = CustomLLM()\n self.template = CustomTemplate(\n \"The answer to {question} is probably {answer} or something ...\"\n )\n\n @instrument\n def retrieve_chunks(self, data):\n return self.retriever.retrieve_chunks(data)\n\n @instrument\n def respond_to_query(self, input):\n chunks = self.retrieve_chunks(input)\n answer = self.llm.generate(\",\".join(chunks))\n output = self.template.fill(question=input, answer=answer)\n\n return output\n\nca = CustomApp()\n
Using instrument.method
from trulens_eval import instrument\n\nclass CustomApp:\n\n def __init__(self):\n self.retriever = CustomRetriever()\n self.llm = CustomLLM()\n self.template = CustomTemplate(\n \"The answer to {question} is probably {answer} or something ...\"\n )\n\n def retrieve_chunks(self, data):\n return self.retriever.retrieve_chunks(data)\n\n def respond_to_query(self, input):\n chunks = self.retrieve_chunks(input)\n answer = self.llm.generate(\",\".join(chunks))\n output = self.template.fill(question=input, answer=answer)\n\n return output\n\ncustom_app = CustomApp()\n\ninstrument.method(CustomApp, \"retrieve_chunks\")\n
Once a method is tracked, its arguments and returns are available to be used in feedback functions. This is done by using the Select class to select the arguments and returns of the method.
Doing so follows the structure:
Defining feedback functions with instrumented methods
f_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve_chunks.args.query) # refers to the query arg of CustomApp's retrieve_chunks method\n .on(Select.RecordCalls.retrieve_chunks.rets.collect())\n .aggregate(np.mean)\n )\n
Last, the TruCustomApp recorder can wrap our custom application, and provide logging and evaluation upon its use.
Using the TruCustomApp recorder
from trulens_eval import TruCustomApp\n\ntru_recorder = TruCustomApp(custom_app, \n app_id=\"Custom Application v1\",\n feedbacks=[f_context_relevance])\n\nwith tru_recorder as recording:\n custom_app.respond_to_query(\"What is the capital of Indonesia?\")\n

Recorder for LlamaIndex applications.
This recorder is designed for LlamaIndex apps, providing a way to instrument, log, and evaluate their behavior.
Creating a LlamaIndex application
Consider an example LlamaIndex application. For the complete code example, see LlamaIndex Quickstart.
from llama_index.core import VectorStoreIndex, SimpleDirectoryReader\n\ndocuments = SimpleDirectoryReader(\"data\").load_data()\nindex = VectorStoreIndex.from_documents(documents)\n\nquery_engine = index.as_query_engine()\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Defining a feedback function
from trulens_eval.feedback.provider import OpenAI\nfrom trulens_eval import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens_eval.app import App\ncontext = App.select_context(rag_chain)\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n
The application can be wrapped in a TruLlama recorder to provide logging and evaluation upon the application's use.
Using the TruLlama recorder
from trulens_eval import TruLlama\n# f_lang_match, f_qa_relevance, f_qs_relevance are feedback functions\ntru_recorder = TruLlama(query_engine,\n app_id='LlamaIndex_App1',\n feedbacks=[f_lang_match, f_qa_relevance, f_qs_relevance])\n\nwith tru_recorder as recording:\n query_engine.query(\"What is llama index?\")\n
Feedback functions can utilize the specific context produced by the application's query engine. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Further information about LlamaIndex apps can be found on the \ud83e\udd99 LlamaIndex Documentation page.

Copy all data from a source database to an EMPTY target database.
Important considerations:
-
All source data will be appended to the target tables, so it is important that the target database is empty.
-
Will fail if the databases are not at the latest schema revision. That can be fixed with Tru(database_url=\"...\", database_prefix=\"...\").migrate_database()
-
Might fail if the target database enforces relationship constraints, because then the order of inserting data matters.
-
This process is NOT transactional, so it is highly recommended that the databases are NOT used by anyone while this process runs.

Bases: WithClassInfo, SerialModel
Base Provider class.
TruLens makes use of Feedback Providers to generate evaluations of large language model applications. These providers act as an access point to different models, most commonly classification models and large language models.
These models are then used to generate feedback on application outputs or intermediate results.
Provider is the base class for all feedback providers. It is an abstract class and should not be instantiated directly. Rather, it should be subclassed and the subclass should implement the methods defined in this class.
There are many feedback providers available in TruLens that grant access to a wide range of proprietary and open-source models.
Providers for classification and other non-LLM models should directly subclass Provider. The feedback functions available for these providers are tied to specific providers, as they rely on provider-specific endpoints to models that are tuned to a particular task.
For example, the Huggingface feedback provider provides access to a number of classification models for specific tasks, such as language detection. These models are than utilized by a feedback function to generate an evaluation score.
Example
from trulens_eval.feedback.provider.hugs import Huggingface\nhuggingface_provider = Huggingface()\nhuggingface_provider.language_match(prompt, response)\n
Providers for LLM models should subclass LLMProvider, which itself subclasses Provider. Providers for LLM-generated feedback are more of a plug-and-play variety. This means that the base model of your choice can be combined with feedback-specific prompting to generate feedback.
For example, relevance can be run with any base LLM feedback provider. Once the feedback provider is instantiated with a base model, the relevance function can be called with a prompt and response.
This means that the base model selected is combined with specific prompting for relevance to generate feedback.
Example
from trulens_eval.feedback.provider.openai import OpenAI\nprovider = OpenAI(model_engine=\"gpt-3.5-turbo\")\nprovider.relevance(prompt, response)\n

Warning
Inspect checkers for async functions do not work on openai clients, perhaps because they use @typing.overload. Because of that, we detect them by checking __wrapped__ attribute instead. Note that the inspect docs suggest they should be able to handle wrapped functions but perhaps they handle different type of wrapping?

Some functions in trulens_eval come with asynchronous versions. Those use \"async def\" instead of \"def\" and typically start with the letter \"a\" in their name with the rest matching their synchronous version.
Due to how python handles such functions and how they are executed, it is relatively difficult to reshare code between the two versions. Asynchronous functions are executed by an async loop (see EventLoop). Python prevents any threads from having more than one running loop meaning one may not be able to create one to run some async code if one has already been created/running in the thread. The method sync here, used to convert an async computation into a sync computation, needs to create a new thread. The impact of this, whether overhead, or record info, is uncertain.

Minimal time/effort-to-value If a user already has an llm app coded in one of the supported libraries, give them some value with the minimal efford beyond that app.
Currently to get going, a user needs to add 4 lines of python:

3 of these lines are fixed so only #3 would vary in typical cases. From here they can open the dashboard and inspect the recording of their app's invocation including performance and cost statistics.

langchain/llama_index callbacks. Each of these packages come with some callback system that lets one get various intermediate app results. The drawbacks is the need to handle different callback systems for each system and potentially missing information not exposed by them.

wrapt package (see https://pypi.org/project/wrapt/)
This is only for wrapping functions or classes to resemble their original but does not help us with wrapping existing methods in langchain, for example. We might be able to use it as part of our own wrapping scheme though.
"},{"location":"trulens_eval/contributing/design/#calls","title":"Calls","text":"
The instrumented versions of functions/methods record the inputs/outputs and some additional data (see [RecordAppCallMethod]trulens_eval.schema.record.RecordAppCallMethod]). As more than one instrumented call may take place as part of a app invokation, they are collected and returned together in the calls field of Record.
Calls can be connected to the components containing the called method via the path field of RecordAppCallMethod. This class also holds information about the instrumented method.
"},{"location":"trulens_eval/contributing/design/#call-data-argumentsreturns","title":"Call Data (Arguments/Returns)","text":"
The arguments to a call and its return are converted to json using the same tools as App Data (see above).
"},{"location":"trulens_eval/contributing/design/#tricky","title":"Tricky","text":"
-
The same method call with the same path may be recorded multiple times in a Record if the method makes use of multiple of its versions in the class hierarchy (i.e. an extended class calls its parents for part of its task). In these circumstances, the method field of RecordAppCallMethod will distinguish the different versions of the method.
-
Thread-safety -- it is tricky to use global data to keep track of instrumented method calls in presence of multiple threads. For this reason we do not use global data and instead hide instrumenting data in the call stack frames of the instrumentation methods. See get_all_local_in_call_stack.
-
Generators and Awaitables -- If an instrumented call produces a generator or awaitable, we cannot produce the full record right away. We instead create a record with placeholder values for the yet-to-be produce pieces. We then instrument (i.e. replace them in the returned data) those pieces with (TODO generators) or awaitables that will update the record when they get eventually awaited (or generated).
"},{"location":"trulens_eval/contributing/design/#threads","title":"Threads","text":"
Threads do not inherit call stacks from their creator. This is a problem due to our reliance on info stored on the stack. Therefore we have a limitation:
- Limitation: Threads need to be started using the utility class TP or ThreadPoolExecutor also defined in
utils/threading.py in order for instrumented methods called in a thread to be tracked. As we rely on call stack for call instrumentation we need to preserve the stack before a thread start which python does not do.
"},{"location":"trulens_eval/contributing/design/#async","title":"Async","text":"
Similar to threads, code run as part of a asyncio.Task does not inherit the stack of the creator. Our current solution instruments asyncio.new_event_loop to make sure all tasks that get created in async track the stack of their creator. This is done in tru_new_event_loop . The function stack_with_tasks is then used to integrate this information with the normal caller stack when needed. This may cause incompatibility issues when other tools use their own event loops or interfere with this instrumentation in other ways. Note that some async functions that seem to not involve Task do use tasks, such as gather.
- Limitation: Tasks must be created via our
task_factory as per task_factory_with_stack. This includes tasks created by function such as asyncio.gather. This limitation is not expected to be a problem given our instrumentation except if other tools are used that modify async in some ways.

-
Threading and async limitations. See Threads and Async .
-
If the same wrapped sub-app is called multiple times within a single call to the root app, the record of this execution will not be exact with regards to the path to the call information. All call paths will address the last subapp (by order in which it is instrumented). For example, in a sequential app containing two of the same app, call records will be addressed to the second of the (same) apps and contain a list describing calls of both the first and second.
TODO(piotrm): This might have been fixed. Check.
-
Some apps cannot be serialized/jsonized. Sequential app is an example. This is a limitation of LangChain itself.

Instrumentation relies on CPython specifics, making heavy use of the inspect module which is not expected to work with other Python implementations.

"},{"location":"trulens_eval/contributing/design/#calls-implementation-details","title":"Calls: Implementation Details","text":"
Our tracking of calls uses instrumentated versions of methods to manage the recording of inputs/outputs. The instrumented methods must distinguish themselves from invocations of apps that are being tracked from those not being tracked, and of those that are tracked, where in the call stack a instrumented method invocation is. To achieve this, we rely on inspecting the python call stack for specific frames:
- Prior frame -- Each instrumented call searches for the topmost instrumented call (except itself) in the stack to check its immediate caller (by immediate we mean only among instrumented methods) which forms the basis of the stack information recorded alongside the inputs/outputs.
"},{"location":"trulens_eval/contributing/design/#drawbacks","title":"Drawbacks","text":"
-
Python call stacks are implementation dependent and we do not expect to operate on anything other than CPython.
-
Python creates a fresh empty stack for each thread. Because of this, we need special handling of each thread created to make sure it keeps a hold of the stack prior to thread creation. Right now we do this in our threading utility class TP but a more complete solution may be the instrumentation of threading.Thread class.
"},{"location":"trulens_eval/contributing/design/#alternatives_2","title":"Alternatives","text":"
-
contextvars -- LangChain uses these to manage contexts such as those used for instrumenting/tracking LLM usage. These can be used to manage call stack information like we do. The drawback is that these are not threadsafe or at least need instrumenting thread creation. We have to do a similar thing by requiring threads created by our utility package which does stack management instead of contextvar management.
NOTE(piotrm): it seems to be standard thing to do to copy the contextvars into new threads so it might be a better idea to use contextvars instead of stack inspection.

Measuring the performance of LLM apps is a critical step in the path from development to production. You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a representative test set.
However unlike in traditional machine learning, ground truth is sparse and often entirely unavailable.
Without ground truth on which to compute metrics on our LLM apps, feedback functions can be used to compute metrics for LLM applications.
"},{"location":"trulens_eval/evaluation/feedback_functions/#what-is-a-feedback-function","title":"What is a feedback function?","text":"
Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. In our view, this method of evaluations is far more useful than general benchmarks because they measure the performance of your app, on your data, for your users.
Important Concept
TruLens constructs feedback functions by combining more general models, known as the feedback provider, and feedback implementation made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
This construction is composable and extensible.
Composable meaning that the user can choose to combine any feedback provider with any feedback implementation.
Extensible meaning that the user can extend a feedback provider with custom feedback implementations of the user's choosing.
Example
In a high stakes domain requiring evaluating long chunks of context, the user may choose to use a more expensive SOTA model.
In lower stakes, higher volume scenarios, the user may choose to use a smaller, cheaper model as the provider.
In either case, any feedback provider can be combined with a TruLens feedback implementation to ultimately compose the feedback function.

Running \"chain of thought evaluations\" is another use case for extending providers. Doing so follows a similar process as above, where the base provider (such as AzureOpenAI) is subclassed.
For this case, the method generate_score_and_reasons can be used to extract both the score and chain of thought reasons from the LLM response.
To use this method, the prompt used should include the COT_REASONS_TEMPLATE available from the TruLens prompts library (trulens_eval.feedback.prompts).

Feedback functions are an extensible framework for evaluating LLMs. You can add your own feedback functions to evaluate the qualities required by your application by updating trulens_eval/feedback.py, or simply creating a new provider class and feedback function in youre notebook. If your contributions would be useful for others, we encourage you to contribute to TruLens!
Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
- Create a new Provider class or locate an existing one that applies to your feedback function. If your feedback function does not rely on a model provider, you can create a standalone class. Add the new feedback function method to your selected class. Your new method can either take a single text (str) as a parameter or both prompt (str) and response (str). It should return a float between 0 (worst) and 1 (best).
"},{"location":"trulens_eval/evaluation/feedback_implementations/custom_feedback_functions/#extending-existing-providers","title":"Extending existing providers.\u00b6","text":"
In addition to calling your own methods, you can also extend stock feedback providers (such as OpenAI, AzureOpenAI, Bedrock) to custom feedback implementations. This can be especially useful for tweaking stock feedback functions, or running custom feedback function prompts while letting TruLens handle the backend LLM provider.
This is done by subclassing the provider you wish to extend, and using the generate_score method that runs the provided prompt with your specified provider, and extracts a float score from 0-1. Your prompt should request the LLM respond on the scale from 0 to 10, then the generate_score method will normalize to 0-1.
See below for example usage:

Trulens also supports multi-output feedback functions. As a typical feedback function will output a float between 0 and 1, multi-output should output a dictionary of output_key to a float between 0 and 1. The feedbacks table will display the feedback with column feedback_name:::outputkey

Feedback selection is the process of determining which components of your application to evaluate.
This is useful because today's LLM applications are increasingly complex. Chaining together components such as planning, retrievel, tool selection, synthesis, and more; each component can be a source of error.
This also makes the instrumentation and evaluation of LLM applications inseparable. To evaluate the inner components of an application, we first need access to them.
As a reminder, a typical feedback definition looks like this:
f_lang_match = Feedback(hugs.language_match)\n .on_input_output()\n
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation. We'll cover that in a later section.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
This flexibility to select and evaluate any component of your application allows the developer to be unconstrained in their creativity. The evaluation framework should not designate how you can build your app.
"},{"location":"trulens_eval/evaluation/feedback_selectors/selecting_components/","title":"Selecting Components","text":"
LLM applications come in all shapes and sizes and with a variety of different control flows. As a result it\u2019s a challenge to consistently evaluate parts of an LLM application trace.
Therefore, we\u2019ve adapted the use of lenses to refer to parts of an LLM stack trace and use those when defining evaluations. For example, the following lens refers to the input to the retrieve step of the app called query.
Example
Select.RecordCalls.retrieve.args.query\n
Such lenses can then be used to define evaluations as so:
Example
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(np.mean)\n)\n
In most cases, the Select object produces only a single item but can also address multiple items.
For example: Select.RecordCalls.retrieve.args.query refers to only one item.
However, Select.RecordCalls.retrieve.rets refers to multiple items. In this case, the documents returned by the retrieve method. These items can be evaluated separately, as shown above, or can be collected into an array for evaluation with .collect(). This is most commonly used for groundedness evaluations.
Example
f_groundedness = (\n Feedback(provider.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n)\n
Selectors can also access multiple calls to the same component. In agentic applications, this is an increasingly common practice. For example, an agent could complete multiple calls to a retrieve method to complete the task required.
For example, the following method returns only the returned context documents from the first invocation of retrieve.
context = Select.RecordCalls.retrieve.rets.rets[:]\n# Same as context = context_method[0].rets[:]\n
Alternatively, adding [:] after the method name retrieve returns context documents from all invocations of retrieve.
context_all_calls = Select.RecordCalls.retrieve[:].rets.rets[:]\n
See also other Select shortcuts.
"},{"location":"trulens_eval/evaluation/feedback_selectors/selecting_components/#understanding-the-structure-of-your-app","title":"Understanding the structure of your app","text":"
Because LLM apps have a wide variation in their structure, the feedback selector construction can also vary widely. To construct the feedback selector, you must first understand the structure of your application.
In python, you can access the JSON structure with with_record methods and then calling layout_calls_as_app.
For example:
response = my_llm_app(query)\n\nfrom trulens_eval import TruChain\ntru_recorder = TruChain(\n my_llm_app,\n app_id='Chain1_ChatApplication')\n\nresponse, tru_record = tru_recorder.with_record(my_llm_app, query)\njson_like = tru_record.layout_calls_as_app()\n
If a selector looks like the below
Select.Record.app.combine_documents_chain._call\n
It can be accessed via the JSON-like via
json_like['app']['combine_documents_chain']['_call']\n
The application structure can also be viewed in the TruLens user inerface. You can view this structure on the Evaluations page by scrolling down to the Timeline.
The top level record also contains these helper accessors
-
RecordInput = Record.main_input -- points to the main input part of a Record. This is the first argument to the root method of an app (for LangChain Chains this is the __call__ method).
-
RecordOutput = Record.main_output -- points to the main output part of a Record. This is the output of the root method of an app (i.e. __call__ for LangChain Chains).
-
RecordCalls = Record.app -- points to the root of the app-structured mirror of calls in a record. See App-organized Calls Section above.
"},{"location":"trulens_eval/evaluation/feedback_selectors/selecting_components/#multiple-inputs-per-argument","title":"Multiple Inputs Per Argument","text":"
As in the f_qs_relevance example, a selector for a single argument may point to more than one aspect of a record/app. These are specified using the slice or lists in key/index poisitions. In that case, the feedback function is evaluated multiple times, its outputs collected, and finally aggregated into a main feedback result.
The collection of values for each argument of feedback implementation is collected and every combination of argument-to-value mapping is evaluated with a feedback definition. This may produce a large number of evaluations if more than one argument names multiple values. In the dashboard, all individual invocations of a feedback implementation are shown alongside the final aggregate result.

When evaluating a feedback function, Records are augmented with app/component calls.

Generating a sufficient test set for evaluating an app is an early change in the development phase.
TruLens allows you to generate a test set of a specified breadth and depth, tailored to your app and data. Resulting test set will be a list of test prompts of length depth, for breadth categories of prompts. Resulting test set will be made up of breadth X depth prompts organized by prompt category.
Example:
from trulens_eval.generate_test_set import GenerateTestSet\n\ntest = GenerateTestSet(app_callable = rag_chain.invoke)\ntest_set = test.generate_test_set(\n test_breadth = 3,\n test_depth = 2\n)\ntest_set\n
Returns:
{'Code implementation': [\n 'What are the steps to follow when implementing code based on the provided instructions?',\n 'What is the required format for each file when outputting the content, including all code?'\n ],\n 'Short term memory limitations': [\n 'What is the capacity of short-term memory and how long does it last?',\n 'What are the two subtypes of long-term memory and what types of information do they store?'\n ],\n 'Planning and task decomposition challenges': [\n 'What are the challenges faced by LLMs in adjusting plans when encountering unexpected errors during long-term planning?',\n 'How does Tree of Thoughts extend the Chain of Thought technique for task decomposition and what search processes can be used in this approach?'\n ]\n}\n
Optionally, you can also provide a list of examples (few-shot) to guide the LLM app to a particular type of question.
Example:
examples = [\n \"What is sensory memory?\",\n \"How much information can be stored in short term memory?\"\n]\n\nfewshot_test_set = test.generate_test_set(\n test_breadth = 3,\n test_depth = 2,\n examples = examples\n)\nfewshot_test_set\n

In many cases, developers have already logged runs of an LLM app they wish to evaluate or wish to log their app using another system. Feedback functions can also be run on existing data, independent of the recorder.
At the most basic level, feedback implementations are simple callables that can be run on any arguments matching their signatures like so:
feedback_result = provider.relevance(\"<some prompt>\", \"<some response>\")\n
Note
Running the feedback implementation in isolation will not log the evaluation results in TruLens.
In the case that you have already logged a run of your application with TruLens and have the record available, the process for running an (additional) evaluation on that record is by using tru.run_feedback_functions:
tru_rag = TruCustomApp(rag, app_id = 'RAG v1')\n\nresult, record = tru_rag.with_record(rag.query, \"How many professors are at UW in Seattle?\")\nfeedback_results = tru.run_feedback_functions(record, feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\ntru.add_feedbacks(feedback_results)\n
"},{"location":"trulens_eval/evaluation/running_feedback_functions/existing_data/#truvirtual","title":"TruVirtual","text":"
If your application was run (and logged) outside of TruLens, TruVirtual can be used to ingest and evaluate the logs.
The first step to loading your app logs into TruLens is creating a virtual app. This virtual app can be a plain dictionary or use our VirtualApp class to store any information you would like. You can refer to these values for evaluating feedback.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\nfrom trulens_eval import Select\nfrom trulens_eval.tru_virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app) # can start with the prior dictionary\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
When setting up the virtual app, you should also include any components that you would like to evaluate in the virtual app. This can be done using the Select class. Using selectors here lets use reuse the setup you use to define feedback functions. Below you can see how to set up a virtual app with a retriever component, which will be used later in the example for feedback evaluation.
from trulens_eval import Select\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
Now that you've set up your virtual app, you can use it to store your logged data.
To incorporate your data into TruLens, you have two options. You can either create a Record directly, or you can use the VirtualRecord class, which is designed to help you build records so they can be ingested to TruLens.
The parameters you'll use with VirtualRecord are the same as those for Record, with one key difference: calls are specified using selectors.
In the example below, we add two records. Each record includes the inputs and outputs for a context retrieval component. Remember, you only need to provide the information that you want to track or evaluate. The selectors are references to methods that can be selected for feedback, as we'll demonstrate below.
from trulens_eval.tru_virtual import VirtualRecord\n\n# The selector for a presumed context retrieval component's call to\n# `get_context`. The names are arbitrary but may be useful for readability on\n# your end.\ncontext_call = retriever_component.get_context\n\nrec1 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Germany is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Germany is a country located in Europe.\"]\n )\n }\n )\nrec2 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Poland is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Poland is a country located in Europe.\"]\n )\n }\n )\n\ndata = [rec1, rec2]\n
Alternatively, suppose we have an existing dataframe of prompts, contexts and responses we wish to ingest.
import pandas as pd\n\ndata = {\n 'prompt': ['Where is Germany?', 'What is the capital of France?'],\n 'response': ['Germany is in Europe', 'The capital of France is Paris'],\n 'context': ['Germany is a country located in Europe.', 'France is a country in Europe and its capital is Paris.']\n}\ndf = pd.DataFrame(data)\ndf.head()\n
To ingest the data in this form, we can iterate through the dataframe to ingest each prompt, context and response into virtual records.
data_dict = df.to_dict('records')\n\ndata = []\n\nfor record in data_dict:\n rec = VirtualRecord(\n main_input=record['prompt'],\n main_output=record['response'],\n calls=\n {\n context_call: dict(\n args=[record['prompt']],\n rets=[record['context']]\n )\n }\n )\n data.append(rec)\n
Now that we've ingested constructed the virtual records, we can build our feedback functions. This is done just the same as normal, except the context selector will instead refer to the new context_call we added to the virtual record.
from trulens_eval.feedback.provider import OpenAI\nfrom trulens_eval.feedback.feedback import Feedback\n\n# Initialize provider class\nopenai = OpenAI()\n\n# Select context to be used in feedback. We select the return values of the\n# virtual `get_context` call in the virtual `retriever` component. Names are\n# arbitrary except for `rets`.\ncontext = context_call.rets[:]\n\n# Question/statement relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(openai.qs_relevance)\n .on_input()\n .on(context)\n)\n
Then, the feedback functions can be passed to TruVirtual to construct the recorder. Most of the fields that other non-virtual apps take can also be specified here.
from trulens_eval.tru_virtual import TruVirtual\n\nvirtual_recorder = TruVirtual(\n app_id=\"a virtual app\",\n app=virtual_app,\n feedbacks=[f_context_relevance]\n)\n
To finally ingest the record and run feedbacks, we can use add_record.
for record in data:\n virtual_recorder.add_record(rec)\n
To optionally store metadata about your application, you can also pass an arbitrary dict to VirtualApp. This information can also be used in evaluation.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nfrom trulens_eval.schema import Select\nfrom trulens_eval.tru_virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\n
The VirtualApp metadata can also be appended.
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
This can be particularly useful for storing the components of an LLM app to be later used for evaluation.
retriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
"},{"location":"trulens_eval/evaluation/running_feedback_functions/with_app/","title":"Running with your app","text":"
The primary method for evaluating LLM apps is by running feedback functions with your app.
To do so, you first need to define the wrap the specified feedback implementation with Feedback and select what components of your app to evaluate. Optionally, you can also select an aggregation method.
f_context_relevance = Feedback(openai.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(numpy.min)\n\n# Implementation signature:\n# def qs_relevance(self, question: str, statement: str) -> float:\n
Once you've defined the feedback functions to run with your application, you can then pass them as a list to the instrumentation class of your choice, along with the app itself. These make up the recorder.
from trulens_eval import TruChain\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruChain(\n chain,\n app_id='Chain1_ChatApplication',\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n
Now that you've included the evaluations as a component of your recorder, they are able to be run with your application. By default, feedback functions will be run in the same process as the app. This is known as the feedback mode: with_app_thread.
with tru_recorder as recording:\n chain(\"\"What is langchain?\")\n
In addition to with_app_thread, there are a number of other manners of running feedback functions. These are accessed by the feedback mode and included when you construct the recorder, like so:
from trulens_eval import FeedbackMode\n\ntru_recorder = TruChain(\n chain,\n app_id='Chain1_ChatApplication',\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance],\n feedback_mode=FeedbackMode.DEFERRED\n )\n
Here are the different feedback modes you can use:
WITH_APP_THREAD: This is the default mode. Feedback functions will run in the same process as the app, but only after the app has produced a record.NONE: In this mode, no evaluation will occur, even if feedback functions are specified.WITH_APP: Feedback functions will run immediately and before the app returns a record.DEFERRED: Feedback functions will be evaluated later via the process started by tru.start_evaluator.

TruLens relies on feedback functions to score the performance of LLM apps, which are implemented across a variety of LLMs and smaller models. The numerical scoring scheme adopted by TruLens' feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts.
Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI, Mistral, and others. Drawing inspiration from works on Judging LLM-as-a-Judge, we outline findings from our analysis of feedback function performance against task-aligned benchmark data. To accomplish this, we first need to align feedback function tasks to relevant benchmarks in order to gain access to large scale ground truth data for the feedback functions. We then are able to easily compute metrics across a variety of implementations and models.

Observing that many summarization benchmarks, such as those found at SummEval, use human annotation of numerical scores, we propose to frame the problem of evaluating groundedness tasks as evaluating a summarization system. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 crowd-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consisntent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases. You are encouraged to run this on your own and even expand the test cases to evaluate performance on test cases applicable to your scenario or domain.

Stand Up Paddle Boarding. Rental and instruction concessions on City of Long Beach Beaches District three.\\nspeaker 1: Can you turn this over to Councilman Price?\\nspeaker 8: Thank you. So this has been an item that we've received a lot of inquiry about over the last couple of weeks, actually, several months. But really, the the item has ramped up the discussion. So with that, I'd like to see if Parks Rec and Marine has a report to share with us that hopefully incorporate some of the\\nspeaker 8: concerns that have been raised.\\nspeaker 3: I'd like to hand this over to L.V. to Halloran, our bureau manager for our Marine Bureau in the Parks Recreation Marine Department, Alveda.\\nspeaker 2: Thank you, Councilwoman and mayor. The city has designated a kiteboarding area in Belmont Shore between Claremont and Laverne Avenue. Kitesurfing, also known as Kiteboarding, is an adventure water sport that is gaining popularity over the last few months and few years.\\nspeaker 2: A car boarder uses a harness, the power of the wind with a large, controllable kite to propel themselves across the water on a kite board that is very similar to a wakeboard or a small surfboard. The wind and surf conditions at Belmont Shore make the Claremont area an ideal site for the sport.\\nspeaker 2: In the spring of 2015, the city began the process of renewing the kite surfing concession permits. A public meeting was held on April 28th, 2015. This meeting was attended by the local residents and by the kite surfing community.\\nspeaker 2: At that meeting, everyone was given the opportunity to voice any concerns that they had or requirements that they would like to see. At that meeting, a compromise regarding the shared use of the beach was reached, and this compromise was presented to the California Coastal Commission.\\nspeaker 2: On July 29, 2015, the California Coastal Commission authorized a coastal development permit for the establishment of the designated Kiteboarding Lesson Area, a Kiteboarding Beach launch and exit area. 315 by 30 foot. Vendor areas. And the issuance of a maximum of three concession permits.\\nspeaker 2: As a result of this, an RFP was advertised in the Press Telegram on April 29th. As you all know, an RFP is a solicitation that provides for a full and open competitive bid process. At the end of the process, the city received five responses to the RFP.\\nspeaker 2: The proposals were evaluated by a committee of city staff who reviewed them against the stated criteria on the RFP and made a determination for award in the best interest of the city. The criteria for selection included several factors such as demonstrated competence, experience in the performance of comparable engagements, expertize, and the availability of key personnel and the\\nspeaker 2: overall conformance responsiveness to the terms of the RFP. The panel selected three responders. Southern California Kiteboarding Off the Hook, Kiteboarding and Captain Kirks, Inc.. Financial Management Purchasing Division sent out the notice of intent to award on June 22nd, 2015.\\nspeaker 2: Two letters of protest were received within the five day protest period. In accordance with the protest procedures, the purchasing and business services manager in the Department of Financial Management evaluated the protest and determined that there was no basis in support of either protest.\\nspeaker 2: Letters of explanation were provided to both the protesters on a moving, moving forward basis. Staff is now requesting the city council authorize us to issue the permits to the selected responders. I'd like to note an important notice here that all licenses and required documents such as a business license, insurance certificates, etc., are required to be valid at\\nspeaker 2: the time of contract issuance. In addition, as a result of a limited limitation placed upon the city by the Coastal Commission and as agreed upon by the Kitesurfing community and the residents, and in the best interest of the city of Long Beach.\\nspeaker 2: Vendors will not have the authorization to engage in the sales of equipment or sundry items as part of the authorized activity on the beach. And in addition to that, they will not be allowed to install permanent kiosk type structures.\\nspeaker 2: That is the end of my report.\\nspeaker 8: Thank you very much for that report. I just have a few follow up questions that I want to make sure that we get clarity on before we vote tonight. So the the three vendors that have been selected through this process, Southern California, Kitesurfing off the hook, Kiteboarding and Captain Kirk's, do they at this time or are they\\nspeaker 8: expected to have all necessary certifications and requirements in place before the permits are executed?\\nspeaker 2: Yes. One of the one of the Coastal Commission requirements was for these individuals to have ICAO's surf certification at the time of the submission of the RFP. The three selected vendors supplied copies of the certification.\\nspeaker 8: Okay. So during this process, it was determined through your methodology that they did have that certification? Yes, ma'am. Okay. And then in regards to those who applied for consideration but were not selected, have any requested meetings with city staff?\\nspeaker 8: And if so, could you give us an overview of efforts to accommodate them and explain the process?\\nspeaker 2: As I mentioned in my staff report to the two of the two incumbents who were not selected, submitted a protest letter through purchasing. Both were. Both were investigated by the manager of the purchasing and Business Business Services and were told that their purchase had no validation.\\nspeaker 2: In addition to that, I myself met with one of the proposers who was not selected, and we discussed at length the reasons why that particular proposal was not selected and why the other ones were selected over that over his proposal.\\nspeaker 8: Okay. Now, I understand that a resident of the city of Long Beach, in fact, of that area, was one of the ones that had applied but wasn't selected. Based on your understanding of the process. Is it is it your opinion that that that particular application either did not meet the qualifications or was not as preferable as the\\nspeaker 8: ones that were selected?\\nspeaker 2: Based on what we what was submitted, the other three incumbents that were that were selected, they ranked higher in our ranking when we went ahead and we reviewed four. Could they demonstrate that they were competent in teaching the board boarding, that they have experience in that area?\\nspeaker 2: Were they able to acquire the key personnel and that they have key personnel already in place, that they expressed financial stability and that they can form and respond to the RFP as requested so that this individual who I sat down with scored at a lower level than the other three.\\nspeaker 8: And I don't want to go into the details of it. I just want to make sure that you feel comfortable that the process was consistent, that it was fair, and that everything that folks wanted considered throughout this process was, in fact considered resulting in a a recommendation that you're comfortable with having gone through this process.\\nspeaker 2: Yes. The process by how it's set up is designed to be fair. So I feel very comfortable, as do the members of my committee, the selection committee that we selected.\\nspeaker 8: Thank you.\\nspeaker 2: Those individuals.\\nspeaker 8: Thank you. Thank you very much for your work on this.\\nspeaker 1: Vice Mayor a long theology of any comments.\\nspeaker 2: Councilman Mongeau I am thrilled that we are exploring Kiteboarding. I think that it is a fantastic sport. It teaches balance and other things young people can learn kiteboarding while standing on the shore. I think it's a great opportunity for Long Beach to get into this active and dynamic industry.\\nspeaker 2: It helps individuals who used to enjoy water skiing behind boats. Take a more environmentally friendly skiing approach, letting the wind pull them in. So I know that members of my family are active kite boarders.

Stand Up Paddle Boarding. Rental and instruction concessions on City of Long Beach Beaches District three.\\nspeaker 1: Can you turn this over to Councilman Price?\\nspeaker 8: Thank you. So this has been an item that we've received a lot of inquiry about over the last couple of weeks, actually, several months. But really, the the item has ramped up the discussion. So with that, I'd like to see if Parks Rec and Marine has a report to share with us that hopefully incorporate some of the\\nspeaker 8: concerns that have been raised.\\nspeaker 3: I'd like to hand this over to L.V. to Halloran, our bureau manager for our Marine Bureau in the Parks Recreation Marine Department, Alveda.\\nspeaker 2: Thank you, Councilwoman and mayor. The city has designated a kiteboarding area in Belmont Shore between Claremont and Laverne Avenue. Kitesurfing, also known as Kiteboarding, is an adventure water sport that is gaining popularity over the last few months and few years.\\nspeaker 2: A car boarder uses a harness, the power of the wind with a large, controllable kite to propel themselves across the water on a kite board that is very similar to a wakeboard or a small surfboard. The wind and surf conditions at Belmont Shore make the Claremont area an ideal site for the sport.\\nspeaker 2: In the spring of 2015, the city began the process of renewing the kite surfing concession permits. A public meeting was held on April 28th, 2015. This meeting was attended by the local residents and by the kite surfing community.\\nspeaker 2: At that meeting, everyone was given the opportunity to voice any concerns that they had or requirements that they would like to see. At that meeting, a compromise regarding the shared use of the beach was reached, and this compromise was presented to the California Coastal Commission.\\nspeaker 2: On July 29, 2015, the California Coastal Commission authorized a coastal development permit for the establishment of the designated Kiteboarding Lesson Area, a Kiteboarding Beach launch and exit area. 315 by 30 foot. Vendor areas. And the issuance of a maximum of three concession permits.\\nspeaker 2: As a result of this, an RFP was advertised in the Press Telegram on April 29th. As you all know, an RFP is a solicitation that provides for a full and open competitive bid process. At the end of the process, the city received five responses to the RFP.\\nspeaker 2: The proposals were evaluated by a committee of city staff who reviewed them against the stated criteria on the RFP and made a determination for award in the best interest of the city. The criteria for selection included several factors such as demonstrated competence, experience in the performance of comparable engagements, expertize, and the availability of key personnel and the\\nspeaker 2: overall conformance responsiveness to the terms of the RFP. The panel selected three responders. Southern California Kiteboarding Off the Hook, Kiteboarding and Captain Kirks, Inc.. Financial Management Purchasing Division sent out the notice of intent to award on June 22nd, 2015.\\nspeaker 2: Two letters of protest were received within the five day protest period. In accordance with the protest procedures, the purchasing and business services manager in the Department of Financial Management evaluated the protest and determined that there was no basis in support of either protest.\\nspeaker 2: Letters of explanation were provided to both the protesters on a moving, moving forward basis. Staff is now requesting the city council authorize us to issue the permits to the selected responders. I'd like to note an important notice here that all licenses and required documents such as a business license, insurance certificates, etc., are required to be valid at\\nspeaker 2: the time of contract issuance. In addition, as a result of a limited limitation placed upon the city by the Coastal Commission and as agreed upon by the Kitesurfing community and the residents, and in the best interest of the city of Long Beach.\\nspeaker 2: Vendors will not have the authorization to engage in the sales of equipment or sundry items as part of the authorized activity on the beach. And in addition to that, they will not be allowed to install permanent kiosk type structures.\\nspeaker 2: That is the end of my report.\\nspeaker 8: Thank you very much for that report. I just have a few follow up questions that I want to make sure that we get clarity on before we vote tonight. So the the three vendors that have been selected through this process, Southern California, Kitesurfing off the hook, Kiteboarding and Captain Kirk's, do they at this time or are they\\nspeaker 8: expected to have all necessary certifications and requirements in place before the permits are executed?\\nspeaker 2: Yes. One of the one of the Coastal Commission requirements was for these individuals to have ICAO's surf certification at the time of the submission of the RFP. The three selected vendors supplied copies of the certification.\\nspeaker 8: Okay. So during this process, it was determined through your methodology that they did have that certification? Yes, ma'am. Okay. And then in regards to those who applied for consideration but were not selected, have any requested meetings with city staff?\\nspeaker 8: And if so, could you give us an overview of efforts to accommodate them and explain the process?\\nspeaker 2: As I mentioned in my staff report to the two of the two incumbents who were not selected, submitted a protest letter through purchasing. Both were. Both were investigated by the manager of the purchasing and Business Business Services and were told that their purchase had no validation.\\nspeaker 2: In addition to that, I myself met with one of the proposers who was not selected, and we discussed at length the reasons why that particular proposal was not selected and why the other ones were selected over that over his proposal.\\nspeaker 8: Okay. Now, I understand that a resident of the city of Long Beach, in fact, of that area, was one of the ones that had applied but wasn't selected. Based on your understanding of the process. Is it is it your opinion that that that particular application either did not meet the qualifications or was not as preferable as the\\nspeaker 8: ones that were selected?\\nspeaker 2: Based on what we what was submitted, the other three incumbents that were that were selected, they ranked higher in our ranking when we went ahead and we reviewed four. Could they demonstrate that they were competent in teaching the board boarding, that they have experience in that area?\\nspeaker 2: Were they able to acquire the key personnel and that they have key personnel already in place, that they expressed financial stability and that they can form and respond to the RFP as requested so that this individual who I sat down with scored at a lower level than the other three.\\nspeaker 8: And I don't want to go into the details of it. I just want to make sure that you feel comfortable that the process was consistent, that it was fair, and that everything that folks wanted considered throughout this process was, in fact considered resulting in a a recommendation that you're comfortable with having gone through this process.\\nspeaker 2: Yes. The process by how it's set up is designed to be fair. So I feel very comfortable, as do the members of my committee, the selection committee that we selected.\\nspeaker 8: Thank you.\\nspeaker 2: Those individuals.\\nspeaker 8: Thank you. Thank you very much for your work on this.\\nspeaker 1: Vice Mayor a long theology of any comments.\\nspeaker 2: Councilman Mongeau I am thrilled that we are exploring Kiteboarding. I think that it is a fantastic sport. It teaches balance and other things young people can learn kiteboarding while standing on the shore. I think it's a great opportunity for Long Beach to get into this active and dynamic industry.\\nspeaker 2: It helps individuals who used to enjoy water skiing behind boats. Take a more environmentally friendly skiing approach, letting the wind pull them in. So I know that members of my family are active kite boarders. I think it's been a great alternative for our family in terms of not going out and polluting lakes and rivers as we've learned\\nspeaker 2: through the years. And so I've been very supportive of this item and I appreciate the great process that the team went through to ensure the fairness of the process.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from MeetingBank to evaluate our comprehensiveness feedback function.
MeetingBank is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the comprehensiveness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5).
For evaluating comprehensiveness feedback functions, we compute the annotated \"informativeness\" scores, a measure of how well the summaries capture all the main points of the meeting segment. A good summary should contain all and only the important information of the source., and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

The numerical scoring scheme adopted by TruLens\u2019 feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts. Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI.
Another frequent inquiry from the community concerns the intrinsic semantic significance, or lack thereof, of feedback scores\u2014for example, how one would interpret and instrument with a score of 0.9 when assessing context relevance in a RAG application or whether a harmfulness score of 0.7 from GPT-3.5 equates to the same from Llama-2-7b.
For simpler meta-evaluation tasks, when human numerical scores are available in the benchmark datasets, such as SummEval, it\u2019s a lot more straightforward to evaluate feedback functions as long as we can define reasonable correlation between the task of the feedback function and the ones available in the benchmarks. Check out our preliminary work on evaluating our own groundedness feedback functions: https://www.trulens.org/trulens_eval/groundedness_smoke_tests/#groundedness-evaluations and our previous blog, where the groundedness metric in the context of RAG can be viewed as equivalent to the consistency metric defined in the SummEval benchmark. In those cases, calculating MAE between our feedback scores and the golden set\u2019s human scores can readily provide insights on how well the groundedness LLM-based feedback functions are aligned with human preferences.
Yet, acquiring high-quality, numerically scored datasets is challenging and costly, a sentiment echoed across institutions and companies working on RLFH dataset annotation.
Observing that many information retrieval (IR) benchmarks use binary labels, we propose to frame the problem of evaluating LLM-based feedback functions (meta-evaluation) as evaluating a recommender system. In essence, we argue the relative importance or ranking based on the score assignments is all you need to achieve meta-evaluation against human golden sets. The intuition is that it is a sufficient proxy to trustworthiness if feedback functions demonstrate discriminative capabilities that reliably and consistently assign items, be it context chunks or generated responses, with weights and ordering closely mirroring human preferences.
In this following section, we illustrate how we conduct meta-evaluation experiments on one of Trulens most widely used feedback functions: context relevance and share how well they are aligned with human preferences in practice.

Here we'll set up our golden set as a set of prompts, responses and expected scores stored in test_cases.py. Then, our numeric_difference method will look up the expected score for each prompt/response pair by exact match. After looking up the expected score, we will then take the L1 difference between the actual score and expected score.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases. You are encouraged to run this on your own and even expand the test cases to evaluate performance on test cases applicable to your scenario or domain.

[{'query': '(CNN)Donald Sterling\\'s racist remarks cost him an NBA team last year. But now it\\'s his former female companion who has lost big. A Los Angeles judge has ordered V. Stiviano to pay back more than $2.6 million in gifts after Sterling\\'s wife sued her. In the lawsuit, Rochelle \"Shelly\" Sterling accused Stiviano of targeting extremely wealthy older men. She claimed Donald Sterling used the couple\\'s money to buy Stiviano a Ferrari, two Bentleys and a Range Rover, and that he helped her get a $1.8 million duplex. Who is V. Stiviano? Stiviano countered that there was nothing wrong with Donald Sterling giving her gifts and that she never took advantage of the former Los Angeles Clippers owner, who made much of his fortune in real estate. Shelly Sterling was thrilled with the court decision Tuesday, her lawyer told CNN affiliate KABC. \"This is a victory for the Sterling family in recovering the $2,630,000 that Donald lavished on a conniving mistress,\" attorney Pierce O\\'Donnell said in a statement. \"It also sets a precedent that the injured spouse can recover damages from the recipient of these ill-begotten gifts.\" Stiviano\\'s gifts from Donald Sterling didn\\'t just include uber-expensive items like luxury cars. According to the Los Angeles Times, the list also includes a $391 Easter bunny costume, a $299 two-speed blender and a $12 lace thong. Donald Sterling\\'s downfall came after an audio recording surfaced of the octogenarian arguing with Stiviano. In the tape, Sterling chastises Stiviano for posting pictures on social media of her posing with African-Americans, including basketball legend Magic Johnson. \"In your lousy f**ing Instagrams, you don\\'t have to have yourself with -- walking with black people,\" Sterling said in the audio first posted by TMZ. He also tells Stiviano not to bring Johnson to Clippers games and not to post photos with the Hall of Famer so Sterling\\'s friends can see. \"Admire him, bring him here, feed him, f**k him, but don\\'t put (Magic) on an Instagram for the world to have to see so they have to call me,\" Sterling said.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 croweded-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consisntent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

General and \ud83e\udd91TruLens-Eval-specific concepts.
-
Agent. A Component of an Application or the entirety of an application that providers a natural language interface to some set of capabilities typically incorporating Tools to invoke or query local or remote services, while maintaining its state via Memory. The user of an agent may be a human, a tool, or another agent. See also Multi Agent System.
-
Application or App. An \"application\" that is tracked by \ud83e\udd91TruLens-Eval. Abstract definition of this tracking corresponds to App. We offer special support for LangChain via TruChain, LlamaIndex via TruLlama, and NeMo Guardrails via TruRails Applications as well as custom apps via TruBasicApp or TruCustomApp, and apps that already come with Traces via TruVirtual.
-
Chain. A LangChain App.
-
Chain of Thought. The use of an Agent to deconstruct its tasks and to structure, analyze, and refine its Completions.
-
Completion, Generation. The process or result of LLM responding to some Prompt.
-
Component. Part of an Application giving it some capability. Common components include:
-
Retriever
-
Memory
-
Tool
-
Agent
-
Prompt Template
-
LLM
-
Embedding. A real vector representation of some piece of text. Can be used to find related pieces of text in a Retrieval.
-
Eval, Evals, Evaluation. Process or result of method that scores the outputs or aspects of a Trace. In \ud83e\udd91TruLens-Eval, our scores are real numbers between 0 and 1.
-
Feedback. See Evaluation.
-
Feedback Function. A method that implements an Evaluation. This corresponds to Feedback.
-
Fine-tuning. The process of training an already pre-trained model on additional data. While the initial training of a Large Language Model is resource intensive (read \"large\"), the subsequent fine-tuning may not be and can improve the performance of the LLM on data that sufficiently deviates or specializes its original training data. Fine-tuning aims to preserve the generality of the original and transfer of its capabilities to specialized tasks. Examples include fining-tuning on:
-
financial articles
-
medical notes
-
synthetic languages (programming or otherwise)
While fine-tuning generally requires access to the original model parameters, some model providers give users the ability to fine-tune through their remote APIs.
-
Generation. See Completion.
-
Human Feedback. A feedback that is provided by a human, e.g. a thumbs up/down in response to a Completion.
-
In-Context Learning. The use of examples in an Instruction Prompt to help an LLM generate intended Completions. See also Shot.
-
Instruction Prompt, System Prompt. A part of a Prompt given to an LLM to complete that contains instructions describing the task that the Completion should solve. Sometimes such prompts include examples of correct or intended completions (see Shots). A prompt that does not include examples is said to be Zero Shot.
-
Language Model. A model whose tasks is to model text distributions typically in the form of predicting token distributions for text that follows the given prefix. Propriety models usually do not give users access to token distributions and instead Complete a piece of input text via multiple token predictions and methods such as beam search.
-
LLM, Large Language Model (see Language Model). The Component of an Application that performs Completion. LLM's are usually trained on a large amount of text across multiple natural and synthetic languages. They are also trained to follow instructions provided in their Instruction Prompt. This makes them general in that they can be applied to many structured or unstructured tasks and even tasks which they have not seen in their training data (See Instruction Prompt, In-Context Learning). LLMs can be further improved to rare/specialized settings using Fine-Tuning.
-
Memory. The state maintained by an Application or an Agent indicating anything relevant to continuing, refining, or guiding it towards its goals. Memory is provided as Context in Prompts and is updated when new relevant context is processed, be it a user prompt or the results of the invocation of some Tool. As Memory is included in Prompts, it can be a natural language description of the state of the app/agent. To limit to size if memory, Summarization is often used.
-
Multi-Agent System. The use of multiple Agents incentivized to interact with each other to implement some capability. While the term predates LLMs, the convenience of the common natural language interface makes the approach much easier to implement.
-
Prompt. The text that an LLM completes during Completion. In chat applications. See also Instruction Prompt, Prompt Template.
-
Prompt Template. A piece of text with placeholders to be filled in in order to build a Prompt for a given task. A Prompt Template will typically include the Instruction Prompt with placeholders for things like Context, Memory, or Application configuration parameters.
-
Provider. A system that provides the ability to execute models, either LLMs or classification models. In \ud83e\udd91TruLens-Eval, Feedback Functions make use of Providers to invoke models for Evaluation.
-
RAG, Retrieval Augmented Generation. A common organization of Applications that combine a Retrieval with an LLM to produce Completions that incorporate information that an LLM alone may not be aware of.
-
RAG Triad (\ud83e\udd91TruLens-Eval-specific concept). A combination of three Feedback Functions meant to Evaluate Retrieval steps in Applications.
-
Record. A \"record\" of the execution of a single execution of an app. Single execution means invocation of some top-level app method. Corresponds to Record
Note
This will be renamed to Trace in the future.
-
Retrieval, Retriever. The process or result (or the Component that performs this) of looking up pieces of text relevant to a Prompt to provide as Context to an LLM. Typically this is done using an Embedding representations.
-
Selector (\ud83e\udd91TruLens-Eval-specific concept). A specification of the source of data from a Trace to use as inputs to a Feedback Function. This corresponds to Lens and utilities Select.
-
Shot, Zero Shot, Few Shot, <Quantity>-Shot. Zero Shot describes prompts that do not have any examples and only offer a natural language description of the task to be solved, while <Quantity>-Shot indicate some <Quantity> of examples are provided. The \"shot\" terminology predates instruction-based LLM's where techniques then used other information to handle unseed classes such as label descriptions in the seen/trained data. In-context Learning is the recent term that describes the use of examples in Instruction Prompts.
-
Span. Some unit of work logged as part of a record. Corresponds to current \ud83e\udd91RecordAppCallMethod.
-
Summarization. The task of condensing some natural language text into a smaller bit of natural language text that preserves the most important parts of the text. This can be targetted towards humans or otherwise. It can also be used to maintain consize Memory in an LLM Application or Agent. Summarization can be performed by an LLM using a specific Instruction Prompt.
-
Tool. A piece of functionality that can be invoked by an Application or Agent. This commonly includes interfaces to services such as search (generic search via google or more specific like IMDB for movies). Tools may also perform actions such as submitting comments to github issues. A Tool may also encapsulate an interface to an Agent for use as a component in a larger Application.
-
Trace. See Record.

Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. The TruLens implementation of feedback functions wrap a supported provider\u2019s model, such as a relevance model or a sentiment classifier, that is repurposed to provide evaluations. Often, for the most flexibility, this model can be another LLM.
It can be useful to think of the range of evaluations on two axis: Scalable and Meaningful.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#domain-expert-ground-truth-evaluations","title":"Domain Expert (Ground Truth) Evaluations","text":"
In early development stages, we recommend starting with domain expert evaluations. These evaluations are often completed by the developers themselves and represent the core use cases your app is expected to complete. This allows you to deeply understand the performance of your app, but lacks scale.
See this example notebook to learn how to run ground truth evaluations with TruLens.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#user-feedback-human-evaluations","title":"User Feedback (Human) Evaluations","text":"
After you have completed early evaluations and have gained more confidence in your app, it is often useful to gather human feedback. This can often be in the form of binary (up/down) feedback provided by your users. This is more slightly scalable than ground truth evals, but struggles with variance and can still be expensive to collect.
See this example notebook to learn how to log human feedback with TruLens.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#traditional-nlp-evaluations","title":"Traditional NLP Evaluations","text":"
Next, it is a common practice to try traditional NLP metrics for evaluations such as BLEU and ROUGE. While these evals are extremely scalable, they are often too syntatic and lack the ability to provide meaningful information on the performance of your app.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#medium-language-model-evaluations","title":"Medium Language Model Evaluations","text":"
Medium Language Models (like BERT) can be a sweet spot for LLM app evaluations at scale. This size of model is relatively cheap to run (scalable) and can also provide nuanced, meaningful feedback on your app. In some cases, these models need to be fine-tuned to provide the right feedback for your domain.
TruLens provides a number of feedback functions out of the box that rely on this style of model such as groundedness NLI, sentiment, language match, moderation and more.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#large-language-model-evaluations","title":"Large Language Model Evaluations","text":"
Large Language Models can also provide meaningful and flexible feedback on LLM app performance. Often through simple prompting, LLM-based evaluations can provide meaningful evaluations that agree with humans at a very high rate. Additionally, they can be easily augmented with LLM-provided reasoning to justify high or low evaluation scores that are useful for debugging.
Depending on the size and nature of the LLM, these evaluations can be quite expensive at scale.

"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/","title":"The RAG Triad","text":"
RAGs have become the standard architecture for providing LLMs with context in order to avoid hallucinations. However even RAGs can suffer from hallucination, as is often the case when the retrieval fails to retrieve sufficient context or even retrieves irrelevant context that is then weaved into the LLM\u2019s response.
TruEra has innovated the RAG triad to evaluate for hallucinations along each edge of the RAG architecture, shown below:
The RAG triad is made up of 3 evaluations: context relevance, groundedness and answer relevance. Satisfactory evaluations on each provides us confidence that our LLM app is free from hallucination.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#context-relevance","title":"Context Relevance","text":"
The first step of any RAG application is retrieval; to verify the quality of our retrieval, we want to make sure that each chunk of context is relevant to the input query. This is critical because this context will be used by the LLM to form an answer, so any irrelevant information in the context could be weaved into a hallucination. TruLens enables you to evaluate context relevance by using the structure of the serialized record.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#groundedness","title":"Groundedness","text":"
After the context is retrieved, it is then formed into an answer by an LLM. LLMs are often prone to stray from the facts provided, exaggerating or expanding to a correct-sounding answer. To verify the groundedness of our application, we can separate the response into individual claims and independently search for evidence that supports each within the retrieved context.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#answer-relevance","title":"Answer Relevance","text":"
Last, our response still needs to helpfully answer the original question. We can verify this by evaluating the relevance of the final response to the user input.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#putting-it-together","title":"Putting it together","text":"
By reaching satisfactory evaluations for this triad, we can make a nuanced statement about our application\u2019s correctness; our application is verified to be hallucination free up to the limit of its knowledge base. In other words, if the vector database contains only accurate information, then the answers provided by the RAG are also accurate.

TruLens is a framework that helps you instrument and evaluate LLM apps including RAGs and agents.
Because TruLens is tech-agnostic, we offer a few different tools for instrumentation.
- TruCustomApp gives you the most power to instrument a custom LLM app, and provides the
instrument method. - TruBasicApp is a simple interface to capture the input and output of a basic LLM app.
- TruChain instruments LangChain apps. Read more.
- TruLlama instruments LlamaIndex apps. Read more.
- TruRails instruments NVIDIA Nemo Guardrails apps. Read more.
In any framework you can track (and evaluate) the intputs, outputs and instrumented internals, along with a wide variety of usage metrics and metadata, detailed below:
"},{"location":"trulens_eval/tracking/instrumentation/#usage-metrics","title":"Usage Metrics\u00b6","text":"

Evaluating LLM applications often requires access to the internals of an app, such as retrieved context. To gain access to these internals, TruLens provides the instrument method. In cases where you have access to the classes and methods required, you can add the @instrument decorator to any method you wish to instrument. See a usage example below:
"},{"location":"trulens_eval/tracking/instrumentation/#using-the-instrument-decorator","title":"Using the
@instrument decorator\u00b6","text":"

In cases you do not have access to a class to make the necessary decorations for tracking, you can instead use one of the static methods of instrument, for example, the alterative for making sure the custom retriever gets instrumented is via instrument.method. See a usage example below:

TruLens provides TruChain, a deep integration with LangChain to allow you to inspect and evaluate the internals of your application built using LangChain.

In addition to the default instrumentation, TruChain exposes the select_context method for evaluations that require access to retrieved context. Exposing select_context bypasses the need to know the json structure of your app ahead of time, and makes your evaluations re-usable across different apps.

TruLens provides TruLlama, a deep integration with LlamaIndex to allow you to inspect and evaluate the internals of your application built using LlamaIndex. This is done through the instrumentation of key LlamaIndex classes and methods. To see all classes and methods instrumented, see Appendix: LlamaIndex Instrumented Classes and Methods.
In addition to the default instrumentation, TruChain exposes the select_context and select_source_nodes methods for evaluations that require access to retrieved context or source nodes. Exposing these methods bypasses the need to know the json structure of your app ahead of time, and makes your evaluations re-usable across different apps.

Additional classes and methods can be instrumented by use of the trulens_eval.instruments.Instrument methods and decorators.

To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retreived context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For Nemo applications with a knowledge base, select_context can be used to access the retrieved text for evaluation.

TruLens provides TruRails, an integration with NeMo Guardrails apps to allow you to inspect and evaluate the internals of your application built using NeMo Guardrails.

What is a tensor? A tensor is a multidimensional object that can be model inputs, or layer activations.
What is a layer? A layer is a set of neurons that can be thought of as a function on input tensors. Layer inputs are tensors. Layer outputs are modified tensors.
What are anchors? Anchors are ways of specifying which tensors you want. You may want the input tensor of a layer, or the output tensor of a layer.
E.g. Say you have a concat layer and you want to explain the 2 concatenated tensors. The concat operation is not usually a layer tracked by the model. If you try the 'in' anchor of the layer after the operation, you get a single tensor with all the information you need.
What is a Quantity of Interest (QoI)? A QoI is a scalar number that is being explained.
E.g. With saliency maps, you get dx/dy (i.e. the effect of input on output). y in this case is the QoI scalar. It is usually the output of a neuron, but could be a sum of multiple neurons.
What is an attribution? An attribution is a numerical value associated with every element in a tensor that explains a QoI.
E.g. With saliency maps, you get dx/dy. x is the associated tensor. The entirety of dx/dy is the explanation.
What are cuts? Cuts are tensors that cut a network into two parts. They are composed of a layer and an anchor.
What are slices? Slices are two cuts leaving a slice of the network. The attribution will be on the first cut, explaining the QoI on the second cut of the slice.
E.g. With saliency maps, the TruLens slice would be AttributionCut: Cut(x) to QoICut: Cut(y), denoted by Slice(Cut(x),Cut(y)).

What is a Distribution of Interest (DoI)?
The distribution of interest is a concept of aggregating attributions over a sample or distribution.
- Grad-CAM (Paper, GitHub, Docs) does this over a Gaussian distribution of inputs.
- Shapley values (GitHub, Docs) do this over different background data.
- Integrated Gradients (Paper, Tutorial) do this over an interpolation from a baseline to the input.
How does this relate to the Attribution Cut?
The sample or distributions are taken at a place that is humanly considered the input, even if this differs from the programmatic model input.
For attributions, all parts of a network can have an attribution towards the QoI. The most common use case is to explain the tensors that are also humanly considered the input (which is where the DoI occurs).
How does this relate to the Baseline Cut?
The Baseline Cut is only applicable to the Integrated Gradients method. It is also only needed when there is no mathematical way to interpolate the baseline to the input.
E.g. if the input is 'Hello', but the baseline is a '[MASK]' token, we cannot interpolate that. We define the baseline at the token layer, but interpolate on a numeric layer like the embeddings.

The numeric scale of the attributions will depend on the specific implementations of the Distribution of Interest and Quantity of Interest. However it is generally related to the scale of gradients on the Quantity of Interest.
For example, Integrated Gradients uses the linear interpolation Distribution of Interest which subsumes the completeness axiom which ensures the sum of all attributions of a record equals the output determined by the Quantity of Interest on the same record.
The Point Distribution of Interest will be determined by the gradient at a single point, thus being a good measure of model sensitivity.
PARAMETER DESCRIPTION
model_args ArgsLike, model_kwargs: KwargsLike The args and kwargs given to the call method of a model. This should represent the records to obtain attributions for, assumed to be a batched input. if self.model supports evaluation on data tensors, the appropriate tensor type may be used (e.g., Pytorch models may accept Pytorch tensors in addition to np.ndarrays). The shape of the inputs must match the input shape of self.model.
TYPE: ArgsLike DEFAULT: ()
Returns - np.ndarray when single attribution_cut input, single qoi output - or ArgsLike[np.ndarray] when single input, multiple output (or vice versa) - or ArgsLike[ArgsLike[np.ndarray]] when multiple output (outer), multiple input (inner)
An array of attributions, matching the shape and type of `from_cut`\nof the slice. Each entry in the returned array represents the degree\nto which the corresponding feature affected the model's outcome on\nthe corresponding point.\n\nIf attributing to a component with multiple inputs, a list for each\nwill be returned.\n\nIf the quantity of interest features multiple outputs, a list for\neach will be returned.\n

Bases: AttributionMethod
Internal attributions parameterized by a slice, quantity of interest, and distribution of interest.
The slice specifies the layers at which the internals of the model are to be exposed; it is represented by two cuts, which specify the layer the attributions are assigned to and the layer from which the quantity of interest is derived. The Quantity of Interest (QoI) is a function of the output specified by the slice that determines the network output behavior that the attributions are to describe. The Distribution of Interest (DoI) specifies the records over which the attributions are aggregated.

If a tuple or list of two Cuts is given, they are assumed to be from_cut and to_cut, respectively.
A cut (or the cuts within the tuple) can also be represented as an int, str, or None. If an int is given, it represents the index of a layer in model. If a str is given, it represents the name of a layer in model. None is an alternative for slices.InputCut.

threshold A threshold to determine the element-wise sign of the input tensor. The elements with activations higher than the threshold will retain their sign, while the elements with activations lower than the threshold will have their sign flipped (or vice versa if low_minus_high is set to True).
TYPE: float
low_minus_high If True, substract the output with activations above the threshold from the output with activations below the threshold. If False, substract the output with activations below the threshold from the output with activations above the threshold.
TYPE: bool DEFAULT: False
activation str or function, optional Activation function to be applied to the quantity before taking the threshold. If activation is a string, use the corresponding activation function implemented by the backend (currently supported: 'sigmoid' and 'softmax'). Otherwise, if activation is not None, it will be treated as a callable. If activation is None, do not apply an activation function to the quantity.

The slice, or layer, of the network provides flexibility over the level of abstraction for the explanation. In a low layer, an explanation may highlight the edges that were most important in identifying an object like a face, while in a higher layer, the explanation might highlight high-level features such as a nose or mouth. By raising the level of abstraction, explanations that generalize over larger sets of samples are possible.

Running \"chain of thought evaluations\" is another use case for extending providers. Doing so follows a similar process as above, where the base provider (such as AzureOpenAI) is subclassed.
For this case, the method generate_score_and_reasons can be used to extract both the score and chain of thought reasons from the LLM response.
To use this method, the prompt used should include the COT_REASONS_TEMPLATE available from the TruLens prompts library (trulens_eval.feedback.prompts).

For demonstration purposes, we start the evaluator here but it can be started in another process.
"},{"location":"trulens_eval/all_tools/#custom-feedback-functions","title":"\ud83d\udcd3 Custom Feedback Functions\u00b6","text":"
Feedback functions are an extensible framework for evaluating LLMs. You can add your own feedback functions to evaluate the qualities required by your application by updating trulens_eval/feedback.py, or simply creating a new provider class and feedback function in youre notebook. If your contributions would be useful for others, we encourage you to contribute to TruLens!
Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
- Create a new Provider class or locate an existing one that applies to your feedback function. If your feedback function does not rely on a model provider, you can create a standalone class. Add the new feedback function method to your selected class. Your new method can either take a single text (str) as a parameter or both prompt (str) and response (str). It should return a float between 0 (worst) and 1 (best).
"},{"location":"trulens_eval/all_tools/#extending-existing-providers","title":"Extending existing providers.\u00b6","text":"
In addition to calling your own methods, you can also extend stock feedback providers (such as OpenAI, AzureOpenAI, Bedrock) to custom feedback implementations. This can be especially useful for tweaking stock feedback functions, or running custom feedback function prompts while letting TruLens handle the backend LLM provider.
This is done by subclassing the provider you wish to extend, and using the generate_score method that runs the provided prompt with your specified provider, and extracts a float score from 0-1. Your prompt should request the LLM respond on the scale from 0 to 10, then the generate_score method will normalize to 0-1.
See below for example usage:
"},{"location":"trulens_eval/all_tools/#multi-output-feedback-functions","title":"Multi-Output Feedback functions\u00b6","text":"
Trulens also supports multi-output feedback functions. As a typical feedback function will output a float between 0 and 1, multi-output should output a dictionary of output_key to a float between 0 and 1. The feedbacks table will display the feedback with column feedback_name:::outputkey

Bases: App
Recorder for LangChain applications.
This recorder is designed for LangChain apps, providing a way to instrument, log, and evaluate their behavior.
Creating a LangChain RAG application
Consider an example LangChain RAG application. For the complete code example, see LangChain Quickstart.
from langchain import hub\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.schema import StrOutputParser\nfrom langchain_core.runnables import RunnablePassthrough\n\nretriever = vectorstore.as_retriever()\n\nprompt = hub.pull(\"rlm/rag-prompt\")\nllm = ChatOpenAI(model_name=\"gpt-3.5-turbo\", temperature=0)\n\nrag_chain = (\n {\"context\": retriever | format_docs, \"question\": RunnablePassthrough()}\n | prompt\n | llm\n | StrOutputParser()\n)\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Defining a feedback function
from trulens_eval.feedback.provider import OpenAI\nfrom trulens_eval import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens_eval.app import App\ncontext = App.select_context(rag_chain)\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n
The application can be wrapped in a TruChain recorder to provide logging and evaluation upon the application's use.
Using the TruChain recorder
from trulens_eval import TruChain\n\n# Wrap application\ntru_recorder = TruChain(\n chain,\n app_id='Chain1_ChatApplication',\n feedbacks=[f_context_relevance]\n)\n\n# Record application runs\nwith tru_recorder as recording:\n chain(\"What is langchain?\")\n
Further information about LangChain apps can be found on the LangChain Documentation page.

Bases: App
This recorder is the most flexible option for instrumenting an application, and can be used to instrument any custom python class.
Track any custom app using methods decorated with @instrument, or whose methods are instrumented after the fact by instrument.method.
Using the @instrument decorator
from trulens_eval import instrument\n\nclass CustomApp:\n\n def __init__(self):\n self.retriever = CustomRetriever()\n self.llm = CustomLLM()\n self.template = CustomTemplate(\n \"The answer to {question} is probably {answer} or something ...\"\n )\n\n @instrument\n def retrieve_chunks(self, data):\n return self.retriever.retrieve_chunks(data)\n\n @instrument\n def respond_to_query(self, input):\n chunks = self.retrieve_chunks(input)\n answer = self.llm.generate(\",\".join(chunks))\n output = self.template.fill(question=input, answer=answer)\n\n return output\n\nca = CustomApp()\n
Using instrument.method
from trulens_eval import instrument\n\nclass CustomApp:\n\n def __init__(self):\n self.retriever = CustomRetriever()\n self.llm = CustomLLM()\n self.template = CustomTemplate(\n \"The answer to {question} is probably {answer} or something ...\"\n )\n\n def retrieve_chunks(self, data):\n return self.retriever.retrieve_chunks(data)\n\n def respond_to_query(self, input):\n chunks = self.retrieve_chunks(input)\n answer = self.llm.generate(\",\".join(chunks))\n output = self.template.fill(question=input, answer=answer)\n\n return output\n\ncustom_app = CustomApp()\n\ninstrument.method(CustomApp, \"retrieve_chunks\")\n
Once a method is tracked, its arguments and returns are available to be used in feedback functions. This is done by using the Select class to select the arguments and returns of the method.
Doing so follows the structure:
Defining feedback functions with instrumented methods
f_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve_chunks.args.query) # refers to the query arg of CustomApp's retrieve_chunks method\n .on(Select.RecordCalls.retrieve_chunks.rets.collect())\n .aggregate(np.mean)\n )\n
Last, the TruCustomApp recorder can wrap our custom application, and provide logging and evaluation upon its use.
Using the TruCustomApp recorder
from trulens_eval import TruCustomApp\n\ntru_recorder = TruCustomApp(custom_app, \n app_id=\"Custom Application v1\",\n feedbacks=[f_context_relevance])\n\nwith tru_recorder as recording:\n custom_app.respond_to_query(\"What is the capital of Indonesia?\")\n

Bases: App
Recorder for LlamaIndex applications.
This recorder is designed for LlamaIndex apps, providing a way to instrument, log, and evaluate their behavior.
Creating a LlamaIndex application
Consider an example LlamaIndex application. For the complete code example, see LlamaIndex Quickstart.
from llama_index.core import VectorStoreIndex, SimpleDirectoryReader\n\ndocuments = SimpleDirectoryReader(\"data\").load_data()\nindex = VectorStoreIndex.from_documents(documents)\n\nquery_engine = index.as_query_engine()\n
Feedback functions can utilize the specific context produced by the application's retriever. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Defining a feedback function
from trulens_eval.feedback.provider import OpenAI\nfrom trulens_eval import Feedback\nimport numpy as np\n\n# Select context to be used in feedback.\nfrom trulens_eval.app import App\ncontext = App.select_context(rag_chain)\n\n# Use feedback\nf_context_relevance = (\n Feedback(provider.context_relevance_with_context_reasons)\n .on_input()\n .on(context) # Refers to context defined from `select_context`\n .aggregate(np.mean)\n)\n
The application can be wrapped in a TruLlama recorder to provide logging and evaluation upon the application's use.
Using the TruLlama recorder
from trulens_eval import TruLlama\n# f_lang_match, f_qa_relevance, f_qs_relevance are feedback functions\ntru_recorder = TruLlama(query_engine,\n app_id='LlamaIndex_App1',\n feedbacks=[f_lang_match, f_qa_relevance, f_qs_relevance])\n\nwith tru_recorder as recording:\n query_engine.query(\"What is llama index?\")\n
Feedback functions can utilize the specific context produced by the application's query engine. This is achieved using the select_context method, which then can be used by a feedback selector, such as on(context).
Further information about LlamaIndex apps can be found on the \ud83e\udd99 LlamaIndex Documentation page.

Bases: App
Recorder for virtual apps.
Virtual apps are data only in that they cannot be executed but for whom previously-computed results can be added using add_record. The VirtualRecord class may be useful for creating records for this. Fields used by non-virtual apps can be specified here, notably:
See App and AppDefinition for constructor arguments.

You can store any information you would like by passing in a dictionary to TruVirtual in the app field. This may involve an index of components or versions, or anything else. You can refer to these values for evaluating feedback.
Usage
You can use VirtualApp to create the app structure or a plain dictionary. Using VirtualApp lets you use Selectors to define components:
virtual_app = VirtualApp()\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
Example
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nvirtual = TruVirtual(\n app_id=\"my_virtual_app\",\n app=virtual_app\n)\n

Copy all data from a source database to an EMPTY target database.
Important considerations:
-
All source data will be appended to the target tables, so it is important that the target database is empty.
-
Will fail if the databases are not at the latest schema revision. That can be fixed with Tru(database_url=\"...\", database_prefix=\"...\").migrate_database()
-
Might fail if the target database enforces relationship constraints, because then the order of inserting data matters.
-
This process is NOT transactional, so it is highly recommended that the databases are NOT used by anyone while this process runs.

Bases: WithClassInfo, SerialModel
Base Provider class.
TruLens makes use of Feedback Providers to generate evaluations of large language model applications. These providers act as an access point to different models, most commonly classification models and large language models.
These models are then used to generate feedback on application outputs or intermediate results.
Provider is the base class for all feedback providers. It is an abstract class and should not be instantiated directly. Rather, it should be subclassed and the subclass should implement the methods defined in this class.
There are many feedback providers available in TruLens that grant access to a wide range of proprietary and open-source models.
Providers for classification and other non-LLM models should directly subclass Provider. The feedback functions available for these providers are tied to specific providers, as they rely on provider-specific endpoints to models that are tuned to a particular task.
For example, the Huggingface feedback provider provides access to a number of classification models for specific tasks, such as language detection. These models are than utilized by a feedback function to generate an evaluation score.
Example
from trulens_eval.feedback.provider.hugs import Huggingface\nhuggingface_provider = Huggingface()\nhuggingface_provider.language_match(prompt, response)\n
Providers for LLM models should subclass LLMProvider, which itself subclasses Provider. Providers for LLM-generated feedback are more of a plug-and-play variety. This means that the base model of your choice can be combined with feedback-specific prompting to generate feedback.
For example, relevance can be run with any base LLM feedback provider. Once the feedback provider is instantiated with a base model, the relevance function can be called with a prompt and response.
This means that the base model selected is combined with specific prompting for relevance to generate feedback.
Example
from trulens_eval.feedback.provider.openai import OpenAI\nprovider = OpenAI(model_engine=\"gpt-3.5-turbo\")\nprovider.relevance(prompt, response)\n

Example
from trulens_eval import Feedback\nfrom trulens_eval.feedback.provider.openai import OpenAI\n\nprovider = OpenAI()\n\nf_groundedness = (\n Feedback(provider.groundedness_measure_with_cot_reasons)\n .on(context.collect()\n .on_output()\n )\n
Args: source: The source that should support the statement. statement: The statement to check groundedness.
RETURNS DESCRIPTION
Tuple[float, dict] Tuple[float, dict]: A tuple containing a value between 0.0 (not grounded) and 1.0 (grounded) and a dictionary containing the reasons for the evaluation.

Some functions in trulens_eval come with asynchronous versions. Those use \"async def\" instead of \"def\" and typically start with the letter \"a\" in their name with the rest matching their synchronous version.
Due to how python handles such functions and how they are executed, it is relatively difficult to reshare code between the two versions. Asynchronous functions are executed by an async loop (see EventLoop). Python prevents any threads from having more than one running loop meaning one may not be able to create one to run some async code if one has already been created/running in the thread. The method sync here, used to convert an async computation into a sync computation, needs to create a new thread. The impact of this, whether overhead, or record info, is uncertain.

- New methods can either take a single text (str) as a parameter or two different texts (str), such as prompt and retrieved context. It should return a float, or a dict of multiple floats. Each output value should be a float on the scale of 0 (worst) to 1 (best).
- Make sure to add its definition to this list.

Feedback functions often rely on a model provider, such as OpenAI or HuggingFace. If you need a new model provider to utilize feedback functions for your use case, we'd love if you added a new provider class, e.g. Ollama.
You can do so by creating a new provider module in this folder.
Alternatively, we also appreciate if you open a GitHub Issue if there's a model provider you need!

Minimal time/effort-to-value If a user already has an llm app coded in one of the supported libraries, give them some value with the minimal efford beyond that app.
Currently to get going, a user needs to add 4 lines of python:
from trulens_eval import Tru # line 1\ntru = Tru() # line 2\nwith tru.Chain(app): # 3\n app.invoke(\"some question\") # doesn't count since they already had this\n\ntru.start_dashboard() # 4\n
3 of these lines are fixed so only #3 would vary in typical cases. From here they can open the dashboard and inspect the recording of their app's invocation including performance and cost statistics. This means trulens must do quite a bit of haggling under the hood to get that data. This is outlined primarily in the Instrumentation section below.

-
intercepts package (see https://github.com/dlshriver/intercepts)
Low level instrumentation of functions but is architecture and platform dependent with no darwin nor arm64 support as of June 07, 2023.
-
sys.setprofile (see https://docs.python.org/3/library/sys.html#sys.setprofile)
Might incur much overhead and all calls and other event types get intercepted and result in a callback.
-
langchain/llama_index callbacks. Each of these packages come with some callback system that lets one get various intermediate app results. The drawbacks is the need to handle different callback systems for each system and potentially missing information not exposed by them.
-
wrapt package (see https://pypi.org/project/wrapt/)
This is only for wrapping functions or classes to resemble their original but does not help us with wrapping existing methods in langchain, for example. We might be able to use it as part of our own wrapping scheme though.
"},{"location":"trulens_eval/contributing/design/#calls","title":"Calls","text":"
The instrumented versions of functions/methods record the inputs/outputs and some additional data (see [RecordAppCallMethod]trulens_eval.schema.record.RecordAppCallMethod]). As more than one instrumented call may take place as part of a app invokation, they are collected and returned together in the calls field of Record.
Calls can be connected to the components containing the called method via the path field of RecordAppCallMethod. This class also holds information about the instrumented method.
"},{"location":"trulens_eval/contributing/design/#call-data-argumentsreturns","title":"Call Data (Arguments/Returns)","text":"
The arguments to a call and its return are converted to json using the same tools as App Data (see above).
"},{"location":"trulens_eval/contributing/design/#tricky","title":"Tricky","text":"
-
The same method call with the same path may be recorded multiple times in a Record if the method makes use of multiple of its versions in the class hierarchy (i.e. an extended class calls its parents for part of its task). In these circumstances, the method field of RecordAppCallMethod will distinguish the different versions of the method.
-
Thread-safety -- it is tricky to use global data to keep track of instrumented method calls in presence of multiple threads. For this reason we do not use global data and instead hide instrumenting data in the call stack frames of the instrumentation methods. See get_all_local_in_call_stack.
-
Generators and Awaitables -- If an instrumented call produces a generator or awaitable, we cannot produce the full record right away. We instead create a record with placeholder values for the yet-to-be produce pieces. We then instrument (i.e. replace them in the returned data) those pieces with (TODO generators) or awaitables that will update the record when they get eventually awaited (or generated).
"},{"location":"trulens_eval/contributing/design/#threads","title":"Threads","text":"
Threads do not inherit call stacks from their creator. This is a problem due to our reliance on info stored on the stack. Therefore we have a limitation:
- Limitation: Threads need to be started using the utility class TP or ThreadPoolExecutor also defined in
utils/threading.py in order for instrumented methods called in a thread to be tracked. As we rely on call stack for call instrumentation we need to preserve the stack before a thread start which python does not do.
"},{"location":"trulens_eval/contributing/design/#async","title":"Async","text":"
Similar to threads, code run as part of a asyncio.Task does not inherit the stack of the creator. Our current solution instruments asyncio.new_event_loop to make sure all tasks that get created in async track the stack of their creator. This is done in tru_new_event_loop . The function stack_with_tasks is then used to integrate this information with the normal caller stack when needed. This may cause incompatibility issues when other tools use their own event loops or interfere with this instrumentation in other ways. Note that some async functions that seem to not involve Task do use tasks, such as gather.
- Limitation: Tasks must be created via our
task_factory as per task_factory_with_stack. This includes tasks created by function such as asyncio.gather. This limitation is not expected to be a problem given our instrumentation except if other tools are used that modify async in some ways.

Threading and async limitations. See Threads and Async .
-
If the same wrapped sub-app is called multiple times within a single call to the root app, the record of this execution will not be exact with regards to the path to the call information. All call paths will address the last subapp (by order in which it is instrumented). For example, in a sequential app containing two of the same app, call records will be addressed to the second of the (same) apps and contain a list describing calls of both the first and second.
TODO(piotrm): This might have been fixed. Check.
-
Some apps cannot be serialized/jsonized. Sequential app is an example. This is a limitation of LangChain itself.

"},{"location":"trulens_eval/contributing/design/#calls-implementation-details","title":"Calls: Implementation Details","text":"
Our tracking of calls uses instrumentated versions of methods to manage the recording of inputs/outputs. The instrumented methods must distinguish themselves from invocations of apps that are being tracked from those not being tracked, and of those that are tracked, where in the call stack a instrumented method invocation is. To achieve this, we rely on inspecting the python call stack for specific frames:
- Prior frame -- Each instrumented call searches for the topmost instrumented call (except itself) in the stack to check its immediate caller (by immediate we mean only among instrumented methods) which forms the basis of the stack information recorded alongside the inputs/outputs.
"},{"location":"trulens_eval/contributing/design/#drawbacks","title":"Drawbacks","text":"
-
Python call stacks are implementation dependent and we do not expect to operate on anything other than CPython.
-
Python creates a fresh empty stack for each thread. Because of this, we need special handling of each thread created to make sure it keeps a hold of the stack prior to thread creation. Right now we do this in our threading utility class TP but a more complete solution may be the instrumentation of threading.Thread class.
"},{"location":"trulens_eval/contributing/design/#alternatives_2","title":"Alternatives","text":"
-
contextvars -- LangChain uses these to manage contexts such as those used for instrumenting/tracking LLM usage. These can be used to manage call stack information like we do. The drawback is that these are not threadsafe or at least need instrumenting thread creation. We have to do a similar thing by requiring threads created by our utility package which does stack management instead of contextvar management.
NOTE(piotrm): it seems to be standard thing to do to copy the contextvars into new threads so it might be a better idea to use contextvars instead of stack inspection.

To handle optional packages and provide clearer instuctions to the user, we employ a context-manager-based scheme (see utils/imports.py) to import packages that may not be installed. The basic form of such imports can be seen in __init__.py:
with OptionalImports(messages=REQUIREMENT_LLAMA):\n from trulens_eval.tru_llama import TruLlama\n
This makes it so that TruLlama gets defined subsequently even if the import fails (because tru_llama imports llama_index which may not be installed). However, if the user imports TruLlama (via __init__.py) and tries to use it (call it, look up attribute, etc), the will be presented a message telling them that llama-index is optional and how to install it:
ModuleNotFoundError: \nllama-index package is required for instrumenting llama_index apps.\nYou should be able to install it with pip:\n\n pip install \"llama-index>=v0.9.14.post3\"\n
If a user imports directly from TruLlama (not by way of __init__.py), they will get that message immediately instead of upon use due to this line inside tru_llama.py:
OptionalImports(messages=REQUIREMENT_LLAMA).assert_installed(llama_index)\n
This checks that the optional import system did not return a replacement for llama_index (under a context manager earlier in the file).
If used in conjunction, the optional imports context manager and assert_installed check can be simplified by storing a reference to to the OptionalImports instance which is returned by the context manager entrace:
with OptionalImports(messages=REQUIREMENT_LLAMA) as opt:\n import llama_index\n ...\n\nopt.assert_installed(llama_index)\n
assert_installed also returns the OptionalImports instance on success so assertions can be chained:

Measuring the performance of LLM apps is a critical step in the path from development to production. You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a representative test set.
However unlike in traditional machine learning, ground truth is sparse and often entirely unavailable.
Without ground truth on which to compute metrics on our LLM apps, feedback functions can be used to compute metrics for LLM applications.

Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. In our view, this method of evaluations is far more useful than general benchmarks because they measure the performance of your app, on your data, for your users.
Important Concept
TruLens constructs feedback functions by combining more general models, known as the feedback provider, and feedback implementation made up of carefully constructed prompts and custom logic tailored to perform a particular evaluation task.
This construction is composable and extensible.
Composable meaning that the user can choose to combine any feedback provider with any feedback implementation.
Extensible meaning that the user can extend a feedback provider with custom feedback implementations of the user's choosing.
Example
In a high stakes domain requiring evaluating long chunks of context, the user may choose to use a more expensive SOTA model.
In lower stakes, higher volume scenarios, the user may choose to use a smaller, cheaper model as the provider.
In either case, any feedback provider can be combined with a TruLens feedback implementation to ultimately compose the feedback function.

OpenAI.context_relevance is an example of a feedback function implementation.
Feedback implementations are simple callables that can be run on any arguments matching their signatures. In the example, the implementation has the following signature:
def context_relevance(self, prompt: str, context: str) -> float:\n
That is, context_relevance is a plain python method that accepts the prompt and context, both strings, and produces a float (assumed to be between 0.0 and 1.0).

The implementation of generation-based feedback functions can consist of:
- Instructions to a generative model (LLM) on how to perform a particular evaluation task. These instructions are sent to the LLM as a system message, and often consist of a rubric.
- A template that passes the arguments of the feedback function to the LLM. This template containing the arguments of the feedback function is sent to the LLM as a user message.
- A method for parsing, validating, and normalizing the output of the LLM, accomplished by
generate_score. - Custom Logic to perform data preprocessing tasks before the LLM is called for evaluation.
- Additional logic to perform postprocessing tasks using the LLM output.
TruLens can also provide reasons using chain-of-thought methodology. Such implementations are denoted by method names ending in _with_cot_reasons. These implementations illicit the LLM to provide reasons for its score, accomplished by generate_score_and_reasons.

Feedback functions are an extensible framework for evaluating LLMs. You can add your own feedback functions to evaluate the qualities required by your application by updating trulens_eval/feedback.py, or simply creating a new provider class and feedback function in youre notebook. If your contributions would be useful for others, we encourage you to contribute to TruLens!
Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
- Create a new Provider class or locate an existing one that applies to your feedback function. If your feedback function does not rely on a model provider, you can create a standalone class. Add the new feedback function method to your selected class. Your new method can either take a single text (str) as a parameter or both prompt (str) and response (str). It should return a float between 0 (worst) and 1 (best).

In addition to calling your own methods, you can also extend stock feedback providers (such as OpenAI, AzureOpenAI, Bedrock) to custom feedback implementations. This can be especially useful for tweaking stock feedback functions, or running custom feedback function prompts while letting TruLens handle the backend LLM provider.
This is done by subclassing the provider you wish to extend, and using the generate_score method that runs the provided prompt with your specified provider, and extracts a float score from 0-1. Your prompt should request the LLM respond on the scale from 0 to 10, then the generate_score method will normalize to 0-1.

Feedback selection is the process of determining which components of your application to evaluate.
This is useful because today's LLM applications are increasingly complex. Chaining together components such as planning, retrievel, tool selection, synthesis, and more; each component can be a source of error.
This also makes the instrumentation and evaluation of LLM applications inseparable. To evaluate the inner components of an application, we first need access to them.
As a reminder, a typical feedback definition looks like this:
f_lang_match = Feedback(hugs.language_match)\n .on_input_output()\n
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation. We'll cover that in a later section.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
This flexibility to select and evaluate any component of your application allows the developer to be unconstrained in their creativity. The evaluation framework should not designate how you can build your app.
"},{"location":"trulens_eval/evaluation/feedback_selectors/selecting_components/","title":"Selecting Components","text":"
LLM applications come in all shapes and sizes and with a variety of different control flows. As a result it\u2019s a challenge to consistently evaluate parts of an LLM application trace.
Therefore, we\u2019ve adapted the use of lenses to refer to parts of an LLM stack trace and use those when defining evaluations. For example, the following lens refers to the input to the retrieve step of the app called query.
Example
Select.RecordCalls.retrieve.args.query\n
Such lenses can then be used to define evaluations as so:
Example
# Context relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n .on(Select.RecordCalls.retrieve.args.query)\n .on(Select.RecordCalls.retrieve.rets)\n .aggregate(np.mean)\n)\n
In most cases, the Select object produces only a single item but can also address multiple items.
For example: Select.RecordCalls.retrieve.args.query refers to only one item.
However, Select.RecordCalls.retrieve.rets refers to multiple items. In this case, the documents returned by the retrieve method. These items can be evaluated separately, as shown above, or can be collected into an array for evaluation with .collect(). This is most commonly used for groundedness evaluations.
Example
f_groundedness = (\n Feedback(provider.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n)\n
Selectors can also access multiple calls to the same component. In agentic applications, this is an increasingly common practice. For example, an agent could complete multiple calls to a retrieve method to complete the task required.
For example, the following method returns only the returned context documents from the first invocation of retrieve.
context = Select.RecordCalls.retrieve.rets.rets[:]\n# Same as context = context_method[0].rets[:]\n
Alternatively, adding [:] after the method name retrieve returns context documents from all invocations of retrieve.
context_all_calls = Select.RecordCalls.retrieve[:].rets.rets[:]\n
See also other Select shortcuts.
"},{"location":"trulens_eval/evaluation/feedback_selectors/selecting_components/#understanding-the-structure-of-your-app","title":"Understanding the structure of your app","text":"
Because LLM apps have a wide variation in their structure, the feedback selector construction can also vary widely. To construct the feedback selector, you must first understand the structure of your application.
In python, you can access the JSON structure with with_record methods and then calling layout_calls_as_app.
For example:
response = my_llm_app(query)\n\nfrom trulens_eval import TruChain\ntru_recorder = TruChain(\n my_llm_app,\n app_id='Chain1_ChatApplication')\n\nresponse, tru_record = tru_recorder.with_record(my_llm_app, query)\njson_like = tru_record.layout_calls_as_app()\n
If a selector looks like the below
Select.Record.app.combine_documents_chain._call\n
It can be accessed via the JSON-like via
json_like['app']['combine_documents_chain']['_call']\n
The application structure can also be viewed in the TruLens user inerface. You can view this structure on the Evaluations page by scrolling down to the Timeline.
The top level record also contains these helper accessors
-
RecordInput = Record.main_input -- points to the main input part of a Record. This is the first argument to the root method of an app (for LangChain Chains this is the __call__ method).
-
RecordOutput = Record.main_output -- points to the main output part of a Record. This is the output of the root method of an app (i.e. __call__ for LangChain Chains).
-
RecordCalls = Record.app -- points to the root of the app-structured mirror of calls in a record. See App-organized Calls Section above.
"},{"location":"trulens_eval/evaluation/feedback_selectors/selecting_components/#multiple-inputs-per-argument","title":"Multiple Inputs Per Argument","text":"
As in the f_qs_relevance example, a selector for a single argument may point to more than one aspect of a record/app. These are specified using the slice or lists in key/index poisitions. In that case, the feedback function is evaluated multiple times, its outputs collected, and finally aggregated into a main feedback result.
The collection of values for each argument of feedback implementation is collected and every combination of argument-to-value mapping is evaluated with a feedback definition. This may produce a large number of evaluations if more than one argument names multiple values. In the dashboard, all individual invocations of a feedback implementation are shown alongside the final aggregate result.

When evaluating a feedback function, Records are augmented with app/component calls. For example, if the instrumented app contains a component combine_docs_chain then app.combine_docs_chain will contain calls to methods of this component. app.combine_docs_chain._call will contain a RecordAppCall (see schema.py) with information about the inputs/outputs/metadata regarding the _call call to that component. Selecting this information is the reason behind the Select.RecordCalls alias.
You can inspect the components making up your app via the App method print_instrumented.

As a reminder, a typical feedback definition looks like this:
f_lang_match = Feedback(hugs.language_match)\n .on_input_output()\n
on_input_output is one of many available shortcuts to simplify the selection of components for evaluation.
The selector, on_input_output, specifies how the language_match arguments are to be determined from an app record or app definition. The general form of this specification is done using on but several shorthands are provided. on_input_output states that the first two argument to language_match (text1 and text2) are to be the main app input and the main output, respectively.
Several utility methods starting with .on provide shorthands:
-
on_input(arg) == on_prompt(arg: Optional[str]) -- both specify that the next unspecified argument or arg should be the main app input.
-
on_output(arg) == on_response(arg: Optional[str]) -- specify that the next argument or arg should be the main app output.
-
on_input_output() == on_input().on_output() -- specifies that the first two arguments of implementation should be the main app input and main app output, respectively.
-
on_default() -- depending on signature of implementation uses either on_output() if it has a single argument, or on_input_output if it has two arguments.
Some wrappers include additional shorthands:

Generating a sufficient test set for evaluating an app is an early change in the development phase.
TruLens allows you to generate a test set of a specified breadth and depth, tailored to your app and data. Resulting test set will be a list of test prompts of length depth, for breadth categories of prompts. Resulting test set will be made up of breadth X depth prompts organized by prompt category.
Example:
from trulens_eval.generate_test_set import GenerateTestSet\n\ntest = GenerateTestSet(app_callable = rag_chain.invoke)\ntest_set = test.generate_test_set(\n test_breadth = 3,\n test_depth = 2\n)\ntest_set\n
Returns:
{'Code implementation': [\n 'What are the steps to follow when implementing code based on the provided instructions?',\n 'What is the required format for each file when outputting the content, including all code?'\n ],\n 'Short term memory limitations': [\n 'What is the capacity of short-term memory and how long does it last?',\n 'What are the two subtypes of long-term memory and what types of information do they store?'\n ],\n 'Planning and task decomposition challenges': [\n 'What are the challenges faced by LLMs in adjusting plans when encountering unexpected errors during long-term planning?',\n 'How does Tree of Thoughts extend the Chain of Thought technique for task decomposition and what search processes can be used in this approach?'\n ]\n}\n
Optionally, you can also provide a list of examples (few-shot) to guide the LLM app to a particular type of question.
Example:
examples = [\n \"What is sensory memory?\",\n \"How much information can be stored in short term memory?\"\n]\n\nfewshot_test_set = test.generate_test_set(\n test_breadth = 3,\n test_depth = 2,\n examples = examples\n)\nfewshot_test_set\n
Returns:

In many cases, developers have already logged runs of an LLM app they wish to evaluate or wish to log their app using another system. Feedback functions can also be run on existing data, independent of the recorder.
At the most basic level, feedback implementations are simple callables that can be run on any arguments matching their signatures like so:
feedback_result = provider.relevance(\"<some prompt>\", \"<some response>\")\n
Note
Running the feedback implementation in isolation will not log the evaluation results in TruLens.
In the case that you have already logged a run of your application with TruLens and have the record available, the process for running an (additional) evaluation on that record is by using tru.run_feedback_functions:
tru_rag = TruCustomApp(rag, app_id = 'RAG v1')\n\nresult, record = tru_rag.with_record(rag.query, \"How many professors are at UW in Seattle?\")\nfeedback_results = tru.run_feedback_functions(record, feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\ntru.add_feedbacks(feedback_results)\n
"},{"location":"trulens_eval/evaluation/running_feedback_functions/existing_data/#truvirtual","title":"TruVirtual","text":"
If your application was run (and logged) outside of TruLens, TruVirtual can be used to ingest and evaluate the logs.
The first step to loading your app logs into TruLens is creating a virtual app. This virtual app can be a plain dictionary or use our VirtualApp class to store any information you would like. You can refer to these values for evaluating feedback.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\nfrom trulens_eval import Select\nfrom trulens_eval.tru_virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app) # can start with the prior dictionary\nvirtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
When setting up the virtual app, you should also include any components that you would like to evaluate in the virtual app. This can be done using the Select class. Using selectors here lets use reuse the setup you use to define feedback functions. Below you can see how to set up a virtual app with a retriever component, which will be used later in the example for feedback evaluation.
from trulens_eval import Select\nretriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
Now that you've set up your virtual app, you can use it to store your logged data.
To incorporate your data into TruLens, you have two options. You can either create a Record directly, or you can use the VirtualRecord class, which is designed to help you build records so they can be ingested to TruLens.
The parameters you'll use with VirtualRecord are the same as those for Record, with one key difference: calls are specified using selectors.
In the example below, we add two records. Each record includes the inputs and outputs for a context retrieval component. Remember, you only need to provide the information that you want to track or evaluate. The selectors are references to methods that can be selected for feedback, as we'll demonstrate below.
from trulens_eval.tru_virtual import VirtualRecord\n\n# The selector for a presumed context retrieval component's call to\n# `get_context`. The names are arbitrary but may be useful for readability on\n# your end.\ncontext_call = retriever_component.get_context\n\nrec1 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Germany is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Germany is a country located in Europe.\"]\n )\n }\n )\nrec2 = VirtualRecord(\n main_input=\"Where is Germany?\",\n main_output=\"Poland is in Europe\",\n calls=\n {\n context_call: dict(\n args=[\"Where is Germany?\"],\n rets=[\"Poland is a country located in Europe.\"]\n )\n }\n )\n\ndata = [rec1, rec2]\n
Alternatively, suppose we have an existing dataframe of prompts, contexts and responses we wish to ingest.
import pandas as pd\n\ndata = {\n 'prompt': ['Where is Germany?', 'What is the capital of France?'],\n 'response': ['Germany is in Europe', 'The capital of France is Paris'],\n 'context': ['Germany is a country located in Europe.', 'France is a country in Europe and its capital is Paris.']\n}\ndf = pd.DataFrame(data)\ndf.head()\n
To ingest the data in this form, we can iterate through the dataframe to ingest each prompt, context and response into virtual records.
data_dict = df.to_dict('records')\n\ndata = []\n\nfor record in data_dict:\n rec = VirtualRecord(\n main_input=record['prompt'],\n main_output=record['response'],\n calls=\n {\n context_call: dict(\n args=[record['prompt']],\n rets=[record['context']]\n )\n }\n )\n data.append(rec)\n
Now that we've ingested constructed the virtual records, we can build our feedback functions. This is done just the same as normal, except the context selector will instead refer to the new context_call we added to the virtual record.
from trulens_eval.feedback.provider import OpenAI\nfrom trulens_eval.feedback.feedback import Feedback\n\n# Initialize provider class\nopenai = OpenAI()\n\n# Select context to be used in feedback. We select the return values of the\n# virtual `get_context` call in the virtual `retriever` component. Names are\n# arbitrary except for `rets`.\ncontext = context_call.rets[:]\n\n# Question/statement relevance between question and each context chunk.\nf_context_relevance = (\n Feedback(openai.qs_relevance)\n .on_input()\n .on(context)\n)\n
Then, the feedback functions can be passed to TruVirtual to construct the recorder. Most of the fields that other non-virtual apps take can also be specified here.
from trulens_eval.tru_virtual import TruVirtual\n\nvirtual_recorder = TruVirtual(\n app_id=\"a virtual app\",\n app=virtual_app,\n feedbacks=[f_context_relevance]\n)\n
To finally ingest the record and run feedbacks, we can use add_record.
for record in data:\n virtual_recorder.add_record(rec)\n
To optionally store metadata about your application, you can also pass an arbitrary dict to VirtualApp. This information can also be used in evaluation.
virtual_app = dict(\n llm=dict(\n modelname=\"some llm component model name\"\n ),\n template=\"information about the template I used in my app\",\n debug=\"all of these fields are completely optional\"\n)\n\nfrom trulens_eval.schema import Select\nfrom trulens_eval.tru_virtual import VirtualApp\n\nvirtual_app = VirtualApp(virtual_app)\n
The VirtualApp metadata can also be appended.
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024\n
This can be particularly useful for storing the components of an LLM app to be later used for evaluation.
retriever_component = Select.RecordCalls.retriever\nvirtual_app[retriever_component] = \"this is the retriever component\"\n
"},{"location":"trulens_eval/evaluation/running_feedback_functions/with_app/","title":"Running with your app","text":"
The primary method for evaluating LLM apps is by running feedback functions with your app.
To do so, you first need to define the wrap the specified feedback implementation with Feedback and select what components of your app to evaluate. Optionally, you can also select an aggregation method.
f_context_relevance = Feedback(openai.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(numpy.min)\n\n# Implementation signature:\n# def qs_relevance(self, question: str, statement: str) -> float:\n
Once you've defined the feedback functions to run with your application, you can then pass them as a list to the instrumentation class of your choice, along with the app itself. These make up the recorder.
from trulens_eval import TruChain\n# f_lang_match, f_qa_relevance, f_context_relevance are feedback functions\ntru_recorder = TruChain(\n chain,\n app_id='Chain1_ChatApplication',\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance])\n
Now that you've included the evaluations as a component of your recorder, they are able to be run with your application. By default, feedback functions will be run in the same process as the app. This is known as the feedback mode: with_app_thread.
with tru_recorder as recording:\n chain(\"\"What is langchain?\")\n
In addition to with_app_thread, there are a number of other manners of running feedback functions. These are accessed by the feedback mode and included when you construct the recorder, like so:
from trulens_eval import FeedbackMode\n\ntru_recorder = TruChain(\n chain,\n app_id='Chain1_ChatApplication',\n feedbacks=[f_lang_match, f_qa_relevance, f_context_relevance],\n feedback_mode=FeedbackMode.DEFERRED\n )\n
Here are the different feedback modes you can use:
WITH_APP_THREAD: This is the default mode. Feedback functions will run in the same process as the app, but only after the app has produced a record.NONE: In this mode, no evaluation will occur, even if feedback functions are specified.WITH_APP: Feedback functions will run immediately and before the app returns a record.DEFERRED: Feedback functions will be evaluated later via the process started by tru.start_evaluator.

TruLens relies on feedback functions to score the performance of LLM apps, which are implemented across a variety of LLMs and smaller models. The numerical scoring scheme adopted by TruLens' feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts.
Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI, Mistral, and others. Drawing inspiration from works on Judging LLM-as-a-Judge, we outline findings from our analysis of feedback function performance against task-aligned benchmark data. To accomplish this, we first need to align feedback function tasks to relevant benchmarks in order to gain access to large scale ground truth data for the feedback functions. We then are able to easily compute metrics across a variety of implementations and models.

Observing that many summarization benchmarks, such as those found at SummEval, use human annotation of numerical scores, we propose to frame the problem of evaluating groundedness tasks as evaluating a summarization system. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 crowd-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consisntent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases. You are encouraged to run this on your own and even expand the test cases to evaluate performance on test cases applicable to your scenario or domain.

Well.\\nspeaker 10: That was pulled as well.\\nspeaker 2: Item ten Report from Parks, Recreation and Marine and Financial Management Recommendation to authorize the city manager to execute three new permits to operate Kiteboarding and stand up paddle boarding. Stand Up Paddle Boarding. Rental and instruction concessions on City of Long Beach Beaches District three.\\nspeaker 1: Can you turn this over to Councilman Price?\\nspeaker 8: Thank you. So this has been an item that we've received a lot of inquiry about over the last couple of weeks, actually, several months. But really, the the item has ramped up the discussion. So with that, I'd like to see if Parks Rec and Marine has a report to share with us that hopefully incorporate some of the\\nspeaker 8: concerns that have been raised.\\nspeaker 3: I'd like to hand this over to L.V. to Halloran, our bureau manager for our Marine Bureau in the Parks Recreation Marine Department, Alveda.\\nspeaker 2: Thank you, Councilwoman and mayor. The city has designated a kiteboarding area in Belmont Shore between Claremont and Laverne Avenue. Kitesurfing, also known as Kiteboarding, is an adventure water sport that is gaining popularity over the last few months and few years.\\nspeaker 2: A car boarder uses a harness, the power of the wind with a large, controllable kite to propel themselves across the water on a kite board that is very similar to a wakeboard or a small surfboard. The wind and surf conditions at Belmont Shore make the Claremont area an ideal site for the sport.\\nspeaker 2: In the spring of 2015, the city began the process of renewing the kite surfing concession permits. A public meeting was held on April 28th, 2015. This meeting was attended by the local residents and by the kite surfing community.\\nspeaker 2: At that meeting, everyone was given the opportunity to voice any concerns that they had or requirements that they would like to see. At that meeting, a compromise regarding the shared use of the beach was reached, and this compromise was presented to the California Coastal Commission.\\nspeaker 2: On July 29, 2015, the California Coastal Commission authorized a coastal development permit for the establishment of the designated Kiteboarding Lesson Area, a Kiteboarding Beach launch and exit area. 315 by 30 foot. Vendor areas. And the issuance of a maximum of three concession permits.\\nspeaker 2: As a result of this, an RFP was advertised in the Press Telegram on April 29th. As you all know, an RFP is a solicitation that provides for a full and open competitive bid process. At the end of the process, the city received five responses to the RFP.\\nspeaker 2: The proposals were evaluated by a committee of city staff who reviewed them against the stated criteria on the RFP and made a determination for award in the best interest of the city. The criteria for selection included several factors such as demonstrated competence, experience in the performance of comparable engagements, expertize, and the availability of key personnel and the\\nspeaker 2: overall conformance responsiveness to the terms of the RFP. The panel selected three responders. Southern California Kiteboarding Off the Hook, Kiteboarding and Captain Kirks, Inc.. Financial Management Purchasing Division sent out the notice of intent to award on June 22nd, 2015.\\nspeaker 2: Two letters of protest were received within the five day protest period. In accordance with the protest procedures, the purchasing and business services manager in the Department of Financial Management evaluated the protest and determined that there was no basis in support of either protest.\\nspeaker 2: Letters of explanation were provided to both the protesters on a moving, moving forward basis. Staff is now requesting the city council authorize us to issue the permits to the selected responders. I'd like to note an important notice here that all licenses and required documents such as a business license, insurance certificates, etc., are required to be valid at\\nspeaker 2: the time of contract issuance. In addition, as a result of a limited limitation placed upon the city by the Coastal Commission and as agreed upon by the Kitesurfing community and the residents, and in the best interest of the city of Long Beach.\\nspeaker 2: Vendors will not have the authorization to engage in the sales of equipment or sundry items as part of the authorized activity on the beach. And in addition to that, they will not be allowed to install permanent kiosk type structures.\\nspeaker 2: That is the end of my report.\\nspeaker 8: Thank you very much for that report. I just have a few follow up questions that I want to make sure that we get clarity on before we vote tonight. So the the three vendors that have been selected through this process, Southern California, Kitesurfing off the hook, Kiteboarding and Captain Kirk's, do they at this time or are they\\nspeaker 8: expected to have all necessary certifications and requirements in place before the permits are executed?\\nspeaker 2: Yes. One of the one of the Coastal Commission requirements was for these individuals to have ICAO's surf certification at the time of the submission of the RFP. The three selected vendors supplied copies of the certification.\\nspeaker 8: Okay. So during this process, it was determined through your methodology that they did have that certification? Yes, ma'am. Okay. And then in regards to those who applied for consideration but were not selected, have any requested meetings with city staff?\\nspeaker 8: And if so, could you give us an overview of efforts to accommodate them and explain the process?\\nspeaker 2: As I mentioned in my staff report to the two of the two incumbents who were not selected, submitted a protest letter through purchasing. Both were. Both were investigated by the manager of the purchasing and Business Business Services and were told that their purchase had no validation.\\nspeaker 2: In addition to that, I myself met with one of the proposers who was not selected, and we discussed at length the reasons why that particular proposal was not selected and why the other ones were selected over that over his proposal.\\nspeaker 8: Okay. Now, I understand that a resident of the city of Long Beach, in fact, of that area, was one of the ones that had applied but wasn't selected. Based on your understanding of the process. Is it is it your opinion that that that particular application either did not meet the qualifications or was not as preferable as the\\nspeaker 8: ones that were selected?\\nspeaker 2: Based on what we what was submitted, the other three incumbents that were that were selected, they ranked higher in our ranking when we went ahead and we reviewed four. Could they demonstrate that they were competent in teaching the board boarding, that they have experience in that area?\\nspeaker 2: Were they able to acquire the key personnel and that they have key personnel already in place, that they expressed financial stability and that they can form and respond to the RFP as requested so that this individual who I sat down with scored at a lower level than the other three.\\nspeaker 8: And I don't want to go into the details of it. I just want to make sure that you feel comfortable that the process was consistent, that it was fair, and that everything that folks wanted considered throughout this process was, in fact considered resulting in a a recommendation that you're comfortable with having gone through this process.\\nspeaker 2: Yes. The process by how it's set up is designed to be fair. So I feel very comfortable, as do the members of my committee, the selection committee that we selected.\\nspeaker 8: Thank you.\\nspeaker 2: Those individuals.\\nspeaker 8: Thank you. Thank you very much for your work on this.\\nspeaker 1: Vice Mayor a long theology of any comments.\\nspeaker 2: Councilman Mongeau I am thrilled that we are exploring Kiteboarding. I think that it is a fantastic sport. It teaches balance and other things young people can learn kiteboarding while standing on the shore. I think it's a great opportunity for Long Beach to get into this active and dynamic industry.\\nspeaker 2: It helps individuals who used to enjoy water skiing behind boats. Take a more environmentally friendly skiing approach, letting the wind pull them in. So I know that members of my family are active kite boarders. I think it's been a great alternative for our family in terms of not going out and polluting lakes and rivers as we've learned\\nspeaker 2: through the years. And so I've been very supportive of this item and I appreciate the great process that the team went through to ensure the fairness of the process. I think that Councilman Price did an excellent job of articulating the importance of that to this council, and I look forward to coming out and seeing many of your\\nspeaker 2: classes and engaging the community in this exciting sport.\\nspeaker 1: Okay. Thank you. A public comment on this item. Seeing nonmembers, please go ahead and cast your votes.\\nspeaker 2: Motion carries.\\nspeaker 1: Okay. Thank you. I'm going to I'm going to go ahead. And also, just because I know we have a lot of our I've been asked because we have a group of seniors here for item 11. Let's just go in here item 11.\\nspeaker 1: I'm sorry, not item 11.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from MeetingBank to evaluate our comprehensiveness feedback function.
MeetingBank is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the comprehensiveness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5).
For evaluating comprehensiveness feedback functions, we compute the annotated \"informativeness\" scores, a measure of how well the summaries capture all the main points of the meeting segment. A good summary should contain all and only the important information of the source., and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

The numerical scoring scheme adopted by TruLens\u2019 feedback functions is intuitive for generating aggregated results from eval runs that are easy to interpret and visualize across different applications of interest. However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts. Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI.
Another frequent inquiry from the community concerns the intrinsic semantic significance, or lack thereof, of feedback scores\u2014for example, how one would interpret and instrument with a score of 0.9 when assessing context relevance in a RAG application or whether a harmfulness score of 0.7 from GPT-3.5 equates to the same from Llama-2-7b.
For simpler meta-evaluation tasks, when human numerical scores are available in the benchmark datasets, such as SummEval, it\u2019s a lot more straightforward to evaluate feedback functions as long as we can define reasonable correlation between the task of the feedback function and the ones available in the benchmarks. Check out our preliminary work on evaluating our own groundedness feedback functions: https://www.trulens.org/trulens_eval/groundedness_smoke_tests/#groundedness-evaluations and our previous blog, where the groundedness metric in the context of RAG can be viewed as equivalent to the consistency metric defined in the SummEval benchmark. In those cases, calculating MAE between our feedback scores and the golden set\u2019s human scores can readily provide insights on how well the groundedness LLM-based feedback functions are aligned with human preferences.
Yet, acquiring high-quality, numerically scored datasets is challenging and costly, a sentiment echoed across institutions and companies working on RLFH dataset annotation.
Observing that many information retrieval (IR) benchmarks use binary labels, we propose to frame the problem of evaluating LLM-based feedback functions (meta-evaluation) as evaluating a recommender system. In essence, we argue the relative importance or ranking based on the score assignments is all you need to achieve meta-evaluation against human golden sets. The intuition is that it is a sufficient proxy to trustworthiness if feedback functions demonstrate discriminative capabilities that reliably and consistently assign items, be it context chunks or generated responses, with weights and ordering closely mirroring human preferences.
In this following section, we illustrate how we conduct meta-evaluation experiments on one of Trulens most widely used feedback functions: context relevance and share how well they are aligned with human preferences in practice.

Here we'll set up our golden set as a set of prompts, responses and expected scores stored in test_cases.py. Then, our numeric_difference method will look up the expected score for each prompt/response pair by exact match. After looking up the expected score, we will then take the L1 difference between the actual score and expected score.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases. You are encouraged to run this on your own and even expand the test cases to evaluate performance on test cases applicable to your scenario or domain.

[{'query': '(CNN)Donald Sterling\\'s racist remarks cost him an NBA team last year. But now it\\'s his former female companion who has lost big. A Los Angeles judge has ordered V. Stiviano to pay back more than $2.6 million in gifts after Sterling\\'s wife sued her. In the lawsuit, Rochelle \"Shelly\" Sterling accused Stiviano of targeting extremely wealthy older men.

In many ways, feedbacks can be thought of as LLM apps themselves. Given text, they return some result. Thinking in this way, we can use TruLens to evaluate and track our feedback quality. We can even do this for different models (e.g. gpt-3.5 and gpt-4) or prompting schemes (such as chain-of-thought reasoning).
This notebook follows an evaluation of a set of test cases generated from human annotated datasets. In particular, we generate test cases from SummEval.
SummEval is one of the datasets dedicated to automated evaluations on summarization tasks, which are closely related to the groundedness evaluation in RAG with the retrieved context (i.e. the source) and response (i.e. the summary). It contains human annotation of numerical score (1 to 5) comprised of scoring from 3 human expert annotators and 5 croweded-sourced annotators. There are 16 models being used for generation in total for 100 paragraphs in the test set, so there are a total of 16,000 machine-generated summaries. Each paragraph also has several human-written summaries for comparative analysis.
For evaluating groundedness feedback functions, we compute the annotated \"consistency\" scores, a measure of whether the summarized response is factually consisntent with the source texts and hence can be used as a proxy to evaluate groundedness in our RAG triad, and normalized to 0 to 1 score as our expected_score and to match the output of feedback functions.

In this release, we re-aligned the groundedness feedback function with other LLM-based feedback functions. It's now faster and easier to define a groundedness feedback function, and can be done with a standard LLM provider rather than importing groundedness on its own. In addition, the custom groundedness aggregation required is now done by default.
Before:
from trulens_eval.feedback.provider.openai import OpenAI\nfrom trulens_eval.feedback import Groundedness\n\nprovider = OpenAI() # or any other LLM-based provider\ngrounded = Groundedness(groundedness_provider=provider)\nf_groundedness = (\n Feedback(grounded.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n .aggregate(grounded.grounded_statements_aggregator)\n)\n
After:
provider = OpenAI()\nf_groundedness = (\n Feedback(provider.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n)\n
This change also applies to the NLI-based groundedness feedback function available from the Huggingface provider.
Before:
from trulens_eval.feedback.provider.openai import Huggingface\nfrom trulens_eval.feedback import Groundedness\n\nfrom trulens_eval.feedback.provider import Huggingface\nhuggingface_provider = Huggingface()\ngrounded = Groundedness(groundedness_provider=huggingface_provider)\n\nf_groundedness = (\n Feedback(grounded.groundedness_measure_with_cot_reasons, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n .aggregate(grounded.grounded_statements_aggregator)\n)\n
After:
from trulens_eval.feedback import Feedback\nfrom trulens_eval.feedback.provider.hugs = Huggingface\n\nhuggingface_provider = Huggingface()\n\nf_groundedness = (\n Feedback(huggingface_provider.groundedness_measure_with_nli, name = \"Groundedness\")\n .on(Select.RecordCalls.retrieve.rets.collect())\n .on_output()\n)\n

General and \ud83e\udd91TruLens-Eval-specific concepts.
-
Agent. A Component of an Application or the entirety of an application that providers a natural language interface to some set of capabilities typically incorporating Tools to invoke or query local or remote services, while maintaining its state via Memory. The user of an agent may be a human, a tool, or another agent. See also Multi Agent System.
-
Application or App. An \"application\" that is tracked by \ud83e\udd91TruLens-Eval. Abstract definition of this tracking corresponds to App. We offer special support for LangChain via TruChain, LlamaIndex via TruLlama, and NeMo Guardrails via TruRails Applications as well as custom apps via TruBasicApp or TruCustomApp, and apps that already come with Traces via TruVirtual.
-
Chain. A LangChain App.
-
Chain of Thought. The use of an Agent to deconstruct its tasks and to structure, analyze, and refine its Completions.
-
Completion, Generation. The process or result of LLM responding to some Prompt.
-
Component. Part of an Application giving it some capability. Common components include:
-
Retriever
-
Memory
-
Tool
-
Agent
-
Prompt Template
-
LLM
-
Embedding. A real vector representation of some piece of text. Can be used to find related pieces of text in a Retrieval.
-
Eval, Evals, Evaluation. Process or result of method that scores the outputs or aspects of a Trace. In \ud83e\udd91TruLens-Eval, our scores are real numbers between 0 and 1.
-
Feedback. See Evaluation.
-
Feedback Function. A method that implements an Evaluation. This corresponds to Feedback.
-
Fine-tuning. The process of training an already pre-trained model on additional data. While the initial training of a Large Language Model is resource intensive (read \"large\"), the subsequent fine-tuning may not be and can improve the performance of the LLM on data that sufficiently deviates or specializes its original training data. Fine-tuning aims to preserve the generality of the original and transfer of its capabilities to specialized tasks. Examples include fining-tuning on:
-
financial articles
-
medical notes
-
synthetic languages (programming or otherwise)
While fine-tuning generally requires access to the original model parameters, some model providers give users the ability to fine-tune through their remote APIs.
-
Generation. See Completion.
-
Human Feedback. A feedback that is provided by a human, e.g. a thumbs up/down in response to a Completion.
-
In-Context Learning. The use of examples in an Instruction Prompt to help an LLM generate intended Completions. See also Shot.
-
Instruction Prompt, System Prompt. A part of a Prompt given to an LLM to complete that contains instructions describing the task that the Completion should solve. Sometimes such prompts include examples of correct or intended completions (see Shots). A prompt that does not include examples is said to be Zero Shot.
-
Language Model. A model whose tasks is to model text distributions typically in the form of predicting token distributions for text that follows the given prefix. Propriety models usually do not give users access to token distributions and instead Complete a piece of input text via multiple token predictions and methods such as beam search.
-
LLM, Large Language Model (see Language Model). The Component of an Application that performs Completion. LLM's are usually trained on a large amount of text across multiple natural and synthetic languages. They are also trained to follow instructions provided in their Instruction Prompt. This makes them general in that they can be applied to many structured or unstructured tasks and even tasks which they have not seen in their training data (See Instruction Prompt, In-Context Learning). LLMs can be further improved to rare/specialized settings using Fine-Tuning.
-
Memory. The state maintained by an Application or an Agent indicating anything relevant to continuing, refining, or guiding it towards its goals. Memory is provided as Context in Prompts and is updated when new relevant context is processed, be it a user prompt or the results of the invocation of some Tool. As Memory is included in Prompts, it can be a natural language description of the state of the app/agent. To limit to size if memory, Summarization is often used.
-
Multi-Agent System. The use of multiple Agents incentivized to interact with each other to implement some capability. While the term predates LLMs, the convenience of the common natural language interface makes the approach much easier to implement.
-
Prompt. The text that an LLM completes during Completion. In chat applications. See also Instruction Prompt, Prompt Template.
-
Prompt Template. A piece of text with placeholders to be filled in in order to build a Prompt for a given task. A Prompt Template will typically include the Instruction Prompt with placeholders for things like Context, Memory, or Application configuration parameters.
-
Provider. A system that provides the ability to execute models, either LLMs or classification models. In \ud83e\udd91TruLens-Eval, Feedback Functions make use of Providers to invoke models for Evaluation.
-
RAG, Retrieval Augmented Generation. A common organization of Applications that combine a Retrieval with an LLM to produce Completions that incorporate information that an LLM alone may not be aware of.
-
RAG Triad (\ud83e\udd91TruLens-Eval-specific concept). A combination of three Feedback Functions meant to Evaluate Retrieval steps in Applications.
-
Record. A \"record\" of the execution of a single execution of an app. Single execution means invocation of some top-level app method. Corresponds to Record
Note
This will be renamed to Trace in the future.
-
Retrieval, Retriever. The process or result (or the Component that performs this) of looking up pieces of text relevant to a Prompt to provide as Context to an LLM. Typically this is done using an Embedding representations.
-
Selector (\ud83e\udd91TruLens-Eval-specific concept). A specification of the source of data from a Trace to use as inputs to a Feedback Function. This corresponds to Lens and utilities Select.
-
Shot, Zero Shot, Few Shot, <Quantity>-Shot. Zero Shot describes prompts that do not have any examples and only offer a natural language description of the task to be solved, while <Quantity>-Shot indicate some <Quantity> of examples are provided. The \"shot\" terminology predates instruction-based LLM's where techniques then used other information to handle unseed classes such as label descriptions in the seen/trained data. In-context Learning is the recent term that describes the use of examples in Instruction Prompts.
-
Span. Some unit of work logged as part of a record. Corresponds to current \ud83e\udd91RecordAppCallMethod.
-
Summarization. The task of condensing some natural language text into a smaller bit of natural language text that preserves the most important parts of the text. This can be targetted towards humans or otherwise. It can also be used to maintain consize Memory in an LLM Application or Agent. Summarization can be performed by an LLM using a specific Instruction Prompt.
-
Tool. A piece of functionality that can be invoked by an Application or Agent. This commonly includes interfaces to services such as search (generic search via google or more specific like IMDB for movies). Tools may also perform actions such as submitting comments to github issues. A Tool may also encapsulate an interface to an Agent for use as a component in a larger Application.
-
Trace. See Record.

Feedback functions, analogous to labeling functions, provide a programmatic method for generating evaluations on an application run. The TruLens implementation of feedback functions wrap a supported provider\u2019s model, such as a relevance model or a sentiment classifier, that is repurposed to provide evaluations. Often, for the most flexibility, this model can be another LLM.
It can be useful to think of the range of evaluations on two axis: Scalable and Meaningful.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#domain-expert-ground-truth-evaluations","title":"Domain Expert (Ground Truth) Evaluations","text":"
In early development stages, we recommend starting with domain expert evaluations. These evaluations are often completed by the developers themselves and represent the core use cases your app is expected to complete. This allows you to deeply understand the performance of your app, but lacks scale.
See this example notebook to learn how to run ground truth evaluations with TruLens.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#user-feedback-human-evaluations","title":"User Feedback (Human) Evaluations","text":"
After you have completed early evaluations and have gained more confidence in your app, it is often useful to gather human feedback. This can often be in the form of binary (up/down) feedback provided by your users. This is more slightly scalable than ground truth evals, but struggles with variance and can still be expensive to collect.
See this example notebook to learn how to log human feedback with TruLens.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#traditional-nlp-evaluations","title":"Traditional NLP Evaluations","text":"
Next, it is a common practice to try traditional NLP metrics for evaluations such as BLEU and ROUGE. While these evals are extremely scalable, they are often too syntatic and lack the ability to provide meaningful information on the performance of your app.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#medium-language-model-evaluations","title":"Medium Language Model Evaluations","text":"
Medium Language Models (like BERT) can be a sweet spot for LLM app evaluations at scale. This size of model is relatively cheap to run (scalable) and can also provide nuanced, meaningful feedback on your app. In some cases, these models need to be fine-tuned to provide the right feedback for your domain.
TruLens provides a number of feedback functions out of the box that rely on this style of model such as groundedness NLI, sentiment, language match, moderation and more.
"},{"location":"trulens_eval/getting_started/core_concepts/feedback_functions/#large-language-model-evaluations","title":"Large Language Model Evaluations","text":"
Large Language Models can also provide meaningful and flexible feedback on LLM app performance. Often through simple prompting, LLM-based evaluations can provide meaningful evaluations that agree with humans at a very high rate. Additionally, they can be easily augmented with LLM-provided reasoning to justify high or low evaluation scores that are useful for debugging.
Depending on the size and nature of the LLM, these evaluations can be quite expensive at scale.

"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/","title":"The RAG Triad","text":"
RAGs have become the standard architecture for providing LLMs with context in order to avoid hallucinations. However even RAGs can suffer from hallucination, as is often the case when the retrieval fails to retrieve sufficient context or even retrieves irrelevant context that is then weaved into the LLM\u2019s response.
TruEra has innovated the RAG triad to evaluate for hallucinations along each edge of the RAG architecture, shown below:
The RAG triad is made up of 3 evaluations: context relevance, groundedness and answer relevance. Satisfactory evaluations on each provides us confidence that our LLM app is free from hallucination.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#context-relevance","title":"Context Relevance","text":"
The first step of any RAG application is retrieval; to verify the quality of our retrieval, we want to make sure that each chunk of context is relevant to the input query. This is critical because this context will be used by the LLM to form an answer, so any irrelevant information in the context could be weaved into a hallucination. TruLens enables you to evaluate context relevance by using the structure of the serialized record.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#groundedness","title":"Groundedness","text":"
After the context is retrieved, it is then formed into an answer by an LLM. LLMs are often prone to stray from the facts provided, exaggerating or expanding to a correct-sounding answer. To verify the groundedness of our application, we can separate the response into individual claims and independently search for evidence that supports each within the retrieved context.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#answer-relevance","title":"Answer Relevance","text":"
Last, our response still needs to helpfully answer the original question. We can verify this by evaluating the relevance of the final response to the user input.
"},{"location":"trulens_eval/getting_started/core_concepts/rag_triad/#putting-it-together","title":"Putting it together","text":"
By reaching satisfactory evaluations for this triad, we can make a nuanced statement about our application\u2019s correctness; our application is verified to be hallucination free up to the limit of its knowledge base. In other words, if the vector database contains only accurate information, then the answers provided by the RAG are also accurate.

Wouldn't it be great if we could automatically filter out context chunks with relevance scores below 0.5?
We can do so with the TruLens guardrail, WithFeedbackFilterDocuments. All we have to do is use the method of_retriever to create a new filtered retriever, passing in the original retriever along with the feedback function and threshold we want to use.

Overview of a LLM-powered autonomous agent system.\\nComponent One: Planning#\\nA complicated task usually involves many steps. An agent needs to know what they are and plan ahead.\\nTask Decomposition#\\nChain of thought (CoT; Wei et al. 2022) has become a standard prompting technique for enhancing model performance on complex tasks. The model is instructed to \u201cthink step by step\u201d to utilize more test-time computation to decompose hard tasks into smaller and simpler steps. CoT transforms big tasks into multiple manageable tasks and shed lights into an interpretation of the model\u2019s thinking process.\\nTree of Thoughts (Yao et al. 2023) extends CoT by exploring multiple reasoning possibilities at each step. It first decomposes the problem into multiple thought steps and generates multiple thoughts per step, creating a tree structure. The search process can be BFS (breadth-first search) or DFS (depth-first search) with each state evaluated by a classifier (via a prompt) or majority vote.\\nTask decomposition can be done (1) by LLM with simple prompting like \"Steps for XYZ.\\\\n1.\", \"What are the subgoals for achieving XYZ?\", (2) by using task-specific instructions; e.g. \"Write a story outline.\" for writing a novel, or (3) with human inputs.\\nAnother quite distinct approach, LLM+P (Liu et al. 2023), involves relying on an external classical planner to do long-horizon planning. This approach utilizes the Planning Domain Definition Language (PDDL) as an intermediate interface to describe the planning problem. In this process, LLM (1) translates the problem into \u201cProblem PDDL\u201d, then (2) requests a classical planner to generate a PDDL plan based on an existing \u201cDomain PDDL\u201d, and finally (3) translates the PDDL plan back into natural language. Essentially, the planning step is outsourced to an external tool, assuming the availability of domain-specific PDDL and a suitable planner which is common in certain robotic setups but not in many other domains.\\nSelf-Reflection#\\nSelf-reflection is a vital aspect that allows autonomous agents to improve iteratively by refining past action decisions and correcting previous mistakes. It plays a crucial role in real-world tasks where trial and error are inevitable.\\nReAct (Yao et al. 2023) integrates reasoning and acting within LLM by extending the action space to be a combination of task-specific discrete actions and the language space. The former enables LLM to interact with the environment (e.g. use Wikipedia search API), while the latter prompting LLM to generate reasoning traces in natural language.\\nThe ReAct prompt template incorporates explicit steps for LLM to think, roughly formatted as:\\nThought: ...\\nAction: ...\\nObservation: ...\\n... (Repeated many times)\\n\\nFig. 2. Examples of reasoning trajectories for knowledge-intensive tasks (e.g. HotpotQA, FEVER) and decision-making tasks (e.g. AlfWorld Env, WebShop). (Image source: Yao et al. 2023).\\nIn both experiments on knowledge-intensive tasks and decision-making tasks, ReAct works better than the Act-only baseline where Thought: \u2026 step is removed.\\nReflexion (Shinn & Labash 2023) is a framework to equips agents with dynamic memory and self-reflection capabilities to improve reasoning skills. Reflexion has a standard RL setup, in which the reward model provides a simple binary reward and the action space follows the setup in ReAct where the task-specific action space is augmented with language to enable complex reasoning steps. After each action $a_t$, the agent computes a heuristic $h_t$ and optionally may decide to reset the environment to start a new trial depending on the self-reflection results.', 'metadata': {'source': 'https://lilianweng.github.io/posts/2023-06-23-agent/'}, 'type': 'Document'}, {'page_content': 'Fig. 10. A picture of a sea otter using rock to crack open a seashell, while floating in the water. While some other animals can use tools, the complexity is not comparable with humans. (Image source: Animals using tools)\\nMRKL (Karpas et al. 2022), short for \u201cModular Reasoning, Knowledge and Language\u201d, is a neuro-symbolic architecture for autonomous agents. A MRKL system is proposed to contain a collection of \u201cexpert\u201d modules and the general-purpose LLM works as a router to route inquiries to the best suitable expert module. These modules can be neural (e.g. deep learning models) or symbolic (e.g. math calculator, currency converter, weather API).\\nThey did an experiment on fine-tuning LLM to call a calculator, using arithmetic as a test case. Their experiments showed that it was harder to solve verbal math problems than explicitly stated math problems because LLMs (7B Jurassic1-large model) failed to extract the right arguments for the basic arithmetic reliably. The results highlight when the external symbolic tools can work reliably, knowing when to and how to use the tools are crucial, determined by the LLM capability.\\nBoth TALM (Tool Augmented Language Models; Parisi et al. 2022) and Toolformer (Schick et al. 2023) fine-tune a LM to learn to use external tool APIs. The dataset is expanded based on whether a newly added API call annotation can improve the quality of model outputs. See more details in the \u201cExternal APIs\u201d section of Prompt Engineering.\\nChatGPT Plugins and OpenAI API function calling are good examples of LLMs augmented with tool use capability working in practice. The collection of tool APIs can be provided by other developers (as in Plugins) or self-defined (as in function calls).\\nHuggingGPT (Shen et al. 2023) is a framework to use ChatGPT as the task planner to select models available in HuggingFace platform according to the model descriptions and summarize the response based on the execution results.\\n\\nFig. 11. Illustration of how HuggingGPT works. (Image source: Shen et al. 2023)\\nThe system comprises of 4 stages:\\n(1) Task planning: LLM works as the brain and parses the user requests into multiple tasks. There are four attributes associated with each task: task type, ID, dependencies, and arguments. They use few-shot examples to guide LLM to do task parsing and planning.\\nInstruction:\\n\\nThe AI assistant can parse user input to several tasks: [{\"task\": task, \"id\", task_id, \"dep\": dependency_task_ids, \"args\": {\"text\": text, \"image\": URL, \"audio\": URL, \"video\": URL}}]. The \"dep\" field denotes the id of the previous task which generates a new resource that the current task relies on. A special tag \"-task_id\" refers to the generated text image, audio and video in the dependency task with id as task_id. The task MUST be selected from the following options: {{ Available Task List }}. There is a logical relationship between tasks, please note their order. If the user input can\\'t be parsed, you need to reply empty JSON. Here are several cases for your reference: {{ Demonstrations }}. The chat history is recorded as {{ Chat History }}.

Overview of a LLM-powered autonomous agent system.\\nComponent One: Planning#\\nA complicated task usually involves many steps. An agent needs to know what they are and plan ahead.\\nTask Decomposition#\\nChain of thought (CoT; Wei et al. 2022) has become a standard prompting technique for enhancing model performance on complex tasks. The model is instructed to \u201cthink step by step\u201d to utilize more test-time computation to decompose hard tasks into smaller and simpler steps. CoT transforms big tasks into multiple manageable tasks and shed lights into an interpretation of the model\u2019s thinking process.\\nTree of Thoughts (Yao et al. 2023) extends CoT by exploring multiple reasoning possibilities at each step. It first decomposes the problem into multiple thought steps and generates multiple thoughts per step, creating a tree structure. The search process can be BFS (breadth-first search) or DFS (depth-first search) with each state evaluated by a classifier (via a prompt) or majority vote.\\nTask decomposition can be done (1) by LLM with simple prompting like \"Steps for XYZ.\\\\n1.\", \"What are the subgoals for achieving XYZ?\", (2) by using task-specific instructions; e.g. \"Write a story outline.\" for writing a novel, or (3) with human inputs.\\nAnother quite distinct approach, LLM+P (Liu et al. 2023), involves relying on an external classical planner to do long-horizon planning. This approach utilizes the Planning Domain Definition Language (PDDL) as an intermediate interface to describe the planning problem. In this process, LLM (1) translates the problem into \u201cProblem PDDL\u201d, then (2) requests a classical planner to generate a PDDL plan based on an existing \u201cDomain PDDL\u201d, and finally (3) translates the PDDL plan back into natural language. Essentially, the planning step is outsourced to an external tool, assuming the availability of domain-specific PDDL and a suitable planner which is common in certain robotic setups but not in many other domains.\\nSelf-Reflection#\\nSelf-reflection is a vital aspect that allows autonomous agents to improve iteratively by refining past action decisions and correcting previous mistakes. It plays a crucial role in real-world tasks where trial and error are inevitable.\\nReAct (Yao et al. 2023) integrates reasoning and acting within LLM by extending the action space to be a combination of task-specific discrete actions and the language space. The former enables LLM to interact with the environment (e.g. use Wikipedia search API), while the latter prompting LLM to generate reasoning traces in natural language.\\nThe ReAct prompt template incorporates explicit steps for LLM to think, roughly formatted as:\\nThought: ...\\nAction: ...\\nObservation: ...\\n... (Repeated many times)\\n\\nFig. 2. Examples of reasoning trajectories for knowledge-intensive tasks (e.g. HotpotQA, FEVER) and decision-making tasks (e.g. AlfWorld Env, WebShop). (Image source: Yao et al. 2023).\\nIn both experiments on knowledge-intensive tasks and decision-making tasks, ReAct works better than the Act-only baseline where Thought: \u2026 step is removed.\\nReflexion (Shinn & Labash 2023) is a framework to equips agents with dynamic memory and self-reflection capabilities to improve reasoning skills. Reflexion has a standard RL setup, in which the reward model provides a simple binary reward and the action space follows the setup in ReAct where the task-specific action space is augmented with language to enable complex reasoning steps. After each action $a_t$, the agent computes a heuristic $h_t$ and optionally may decide to reset the environment to start a new trial depending on the self-reflection results.']}, rets=0.7, error=None, perf=Perf(start_time=datetime.datetime(2024, 6, 13, 10, 50, 27, 822204), end_time=datetime.datetime(2024, 6, 13, 10, 50, 28, 281915)), pid=65698, tid=6453381), RecordAppCall(call_id='e14d5a31-4785-457f-8c83-42d02d9552f1', stack=[RecordAppCallMethod(path=Lens().app, method=Method(obj=Obj(cls=langchain_core.runnables.base.RunnableSequence, id=6414884560, init_bindings=None), name='invoke')), RecordAppCallMethod(path=Lens().app.first, method=Method(obj=Obj(cls=langchain_core.runnables.base.RunnableParallel, id=13886132880, init_bindings=None), name='invoke')), RecordAppCallMethod(path=Lens().app.first.steps__.context, method=Method(obj=Obj(cls=langchain_core.runnables.base.RunnableSequence, id=6414884560, init_bindings=None), name='invoke')), RecordAppCallMethod(path=Lens().app.first.steps__.context.first, method=Method(obj=Obj(cls=trulens_eval.guardrails.langchain.WithFeedbackFilterDocuments, id=13914853328, init_bindings=None), name='invoke')), RecordAppCallMethod(path=Lens().app.first.steps__.context.first, method=Method(obj=Obj(cls=trulens_eval.guardrails.langchain.WithFeedbackFilterDocuments, id=13914853328, init_bindings=None), name='_get_relevant_documents')), RecordAppCallMethod(path=Lens().app.first.steps__.context.first.feedback, method=Method(obj=Obj(cls=trulens_eval.feedback.feedback.Feedback, id=13885261616, init_bindings=None), name='__call__'))], args={'args': ['What is Task Decomposition?', 'Fig. 10.

A MRKL system is proposed to contain a collection of \u201cexpert\u201d modules and the general-purpose LLM works as a router to route inquiries to the best suitable expert module. These modules can be neural (e.g. deep learning models) or symbolic (e.g. math calculator, currency converter, weather API).\\nThey did an experiment on fine-tuning LLM to call a calculator, using arithmetic as a test case. Their experiments showed that it was harder to solve verbal math problems than explicitly stated math problems because LLMs (7B Jurassic1-large model) failed to extract the right arguments for the basic arithmetic reliably. The results highlight when the external symbolic tools can work reliably, knowing when to and how to use the tools are crucial, determined by the LLM capability.\\nBoth TALM (Tool Augmented Language Models; Parisi et al. 2022) and Toolformer (Schick et al. 2023) fine-tune a LM to learn to use external tool APIs.

There are four attributes associated with each task: task type, ID, dependencies, and arguments. They use few-shot examples to guide LLM to do task parsing and planning.\\nInstruction:\\n\\nThe AI assistant can parse user input to several tasks: [{\"task\": task, \"id\", task_id, \"dep\": dependency_task_ids, \"args\": {\"text\": text, \"image\": URL, \"audio\": URL, \"video\": URL}}]. The \"dep\" field denotes the id of the previous task which generates a new resource that the current task relies on. A special tag \"-task_id\" refers to the generated text image, audio and video in the dependency task with id as task_id. The task MUST be selected from the following options: {{ Available Task List }}. There is a logical relationship between tasks, please note their order. If the user input can\\'t be parsed, you need to reply empty JSON. Here are several cases for your reference: {{ Demonstrations }}. The chat history is recorded as {{ Chat History }}.

Overview of a LLM-powered autonomous agent system.\\nComponent One: Planning#\\nA complicated task usually involves many steps. An agent needs to know what they are and plan ahead.\\nTask Decomposition#\\nChain of thought (CoT; Wei et al. 2022) has become a standard prompting technique for enhancing model performance on complex tasks. The model is instructed to \u201cthink step by step\u201d to utilize more test-time computation to decompose hard tasks into smaller and simpler steps. CoT transforms big tasks into multiple manageable tasks and shed lights into an interpretation of the model\u2019s thinking process.\\nTree of Thoughts (Yao et al. 2023) extends CoT by exploring multiple reasoning possibilities at each step. It first decomposes the problem into multiple thought steps and generates multiple thoughts per step, creating a tree structure. The search process can be BFS (breadth-first search) or DFS (depth-first search) with each state evaluated by a classifier (via a prompt) or majority vote.\\nTask decomposition can be done (1) by LLM with simple prompting like \"Steps for XYZ.\\\\n1.\", \"What are the subgoals for achieving XYZ?\", (2) by using task-specific instructions; e.g. \"Write a story outline.\" for writing a novel, or (3) with human inputs.\\nAnother quite distinct approach, LLM+P (Liu et al. 2023), involves relying on an external classical planner to do long-horizon planning. This approach utilizes the Planning Domain Definition Language (PDDL) as an intermediate interface to describe the planning problem. In this process, LLM (1) translates the problem into \u201cProblem PDDL\u201d, then (2) requests a classical planner to generate a PDDL plan based on an existing \u201cDomain PDDL\u201d, and finally (3) translates the PDDL plan back into natural language. Essentially, the planning step is outsourced to an external tool, assuming the availability of domain-specific PDDL and a suitable planner which is common in certain robotic setups but not in many other domains.\\nSelf-Reflection#\\nSelf-reflection is a vital aspect that allows autonomous agents to improve iteratively by refining past action decisions and correcting previous mistakes. It plays a crucial role in real-world tasks where trial and error are inevitable.\\nReAct (Yao et al. 2023) integrates reasoning and acting within LLM by extending the action space to be a combination of task-specific discrete actions and the language space. The former enables LLM to interact with the environment (e.g. use Wikipedia search API), while the latter prompting LLM to generate reasoning traces in natural language.\\nThe ReAct prompt template incorporates explicit steps for LLM to think, roughly formatted as:\\nThought: ...\\nAction: ...\\nObservation: ...\\n...

A MRKL system is proposed to contain a collection of \u201cexpert\u201d modules and the general-purpose LLM works as a router to route inquiries to the best suitable expert module. These modules can be neural (e.g. deep learning models) or symbolic (e.g. math calculator, currency converter, weather API).\\nThey did an experiment on fine-tuning LLM to call a calculator, using arithmetic as a test case. Their experiments showed that it was harder to solve verbal math problems than explicitly stated math problems because LLMs (7B Jurassic1-large model) failed to extract the right arguments for the basic arithmetic reliably. The results highlight when the external symbolic tools can work reliably, knowing when to and how to use the tools are crucial, determined by the LLM capability.\\nBoth TALM (Tool Augmented Language Models; Parisi et al. 2022) and Toolformer (Schick et al. 2023) fine-tune a LM to learn to use external tool APIs. The dataset is expanded based on whether a newly added API call annotation can improve the quality of model outputs. See more details in the \u201cExternal APIs\u201d section of Prompt Engineering.\\nChatGPT Plugins and OpenAI API function calling are good examples of LLMs augmented with tool use capability working in practice. The collection of tool APIs can be provided by other developers (as in Plugins) or self-defined (as in function calls).\\nHuggingGPT (Shen et al. 2023) is a framework to use ChatGPT as the task planner to select models available in HuggingFace platform according to the model descriptions and summarize the response based on the execution results.\\n\\nFig. 11. Illustration of how HuggingGPT works. (Image source: Shen et al. 2023)\\nThe system comprises of 4 stages:\\n(1) Task planning: LLM works as the brain and parses the user requests into multiple tasks. There are four attributes associated with each task: task type, ID, dependencies, and arguments. They use few-shot examples to guide LLM to do task parsing and planning.\\nInstruction:\\n\\nThe AI assistant can parse user input to several tasks: [{\"task\": task, \"id\", task_id, \"dep\": dependency_task_ids, \"args\": {\"text\": text, \"image\": URL, \"audio\": URL, \"video\": URL}}]. The \"dep\" field denotes the id of the previous task which generates a new resource that the current task relies on. A special tag \"-task_id\" refers to the generated text image, audio and video in the dependency task with id as task_id. The task MUST be selected from the following options: {{ Available Task List }}. There is a logical relationship between tasks, please note their order. If the user input can\\'t be parsed, you need to reply empty JSON. Here are several cases for your reference: {{ Demonstrations }}. The chat history is recorded as {{ Chat History }}. From this chat history, you can find the path of the user-mentioned resources for your task planning.\\n\\n(2) Model selection: LLM distributes the tasks to expert models, where the request is framed as a multiple-choice question. LLM is presented with a list of models to choose from. Due to the limited context length, task type based filtration is needed.\\nInstruction:\\n\\nGiven the user request and the call command, the AI assistant helps the user to select a suitable model from a list of models to process the user request.

Overview of a LLM-powered autonomous agent system.\\nComponent One: Planning#\\nA complicated task usually involves many steps. An agent needs to know what they are and plan ahead.\\nTask Decomposition#\\nChain of thought (CoT; Wei et al. 2022) has become a standard prompting technique for enhancing model performance on complex tasks. The model is instructed to \u201cthink step by step\u201d to utilize more test-time computation to decompose hard tasks into smaller and simpler steps. CoT transforms big tasks into multiple manageable tasks and shed lights into an interpretation of the model\u2019s thinking process.\\nTree of Thoughts (Yao et al. 2023) extends CoT by exploring multiple reasoning possibilities at each step. It first decomposes the problem into multiple thought steps and generates multiple thoughts per step, creating a tree structure. The search process can be BFS (breadth-first search) or DFS (depth-first search) with each state evaluated by a classifier (via a prompt) or majority vote.\\nTask decomposition can be done (1) by LLM with simple prompting like \"Steps for XYZ.\\\\n1.\", \"What are the subgoals for achieving XYZ?\", (2) by using task-specific instructions; e.g. \"Write a story outline.\" for writing a novel, or (3) with human inputs.\\nAnother quite distinct approach, LLM+P (Liu et al. 2023), involves relying on an external classical planner to do long-horizon planning. This approach utilizes the Planning Domain Definition Language (PDDL) as an intermediate interface to describe the planning problem. In this process, LLM (1) translates the problem into \u201cProblem PDDL\u201d, then (2) requests a classical planner to generate a PDDL plan based on an existing \u201cDomain PDDL\u201d, and finally (3) translates the PDDL plan back into natural language. Essentially, the planning step is outsourced to an external tool, assuming the availability of domain-specific PDDL and a suitable planner which is common in certain robotic setups but not in many other domains.\\nSelf-Reflection#\\nSelf-reflection is a vital aspect that allows autonomous agents to improve iteratively by refining past action decisions and correcting previous mistakes. It plays a crucial role in real-world tasks where trial and error are inevitable.\\nReAct (Yao et al. 2023) integrates reasoning and acting within LLM by extending the action space to be a combination of task-specific discrete actions and the language space. The former enables LLM to interact with the environment (e.g. use Wikipedia search API), while the latter prompting LLM to generate reasoning traces in natural language.\\nThe ReAct prompt template incorporates explicit steps for LLM to think, roughly formatted as:\\nThought: ...\\nAction: ...\\nObservation: ...\\n... (Repeated many times)\\n\\nFig. 2. Examples of reasoning trajectories for knowledge-intensive tasks (e.g. HotpotQA, FEVER) and decision-making tasks (e.g. AlfWorld Env, WebShop). (Image source: Yao et al. 2023).\\nIn both experiments on knowledge-intensive tasks and decision-making tasks, ReAct works better than the Act-only baseline where Thought: \u2026 step is removed.\\nReflexion (Shinn & Labash 2023) is a framework to equips agents with dynamic memory and self-reflection capabilities to improve reasoning skills. Reflexion has a standard RL setup, in which the reward model provides a simple binary reward and the action space follows the setup in ReAct where the task-specific action space is augmented with language to enable complex reasoning steps. After each action $a_t$, the agent computes a heuristic $h_t$ and optionally may decide to reset the environment to start a new trial depending on the self-reflection results.']}, 'rets': 0.7, 'error': None, 'perf': {'start_time': '2024-06-13T10:50:27.822204', 'end_time': '2024-06-13T10:50:28.281915'}, 'pid': 65698, 'tid': 6453381}, {'call_id': 'e14d5a31-4785-457f-8c83-42d02d9552f1', 'stack': [{'path': 'app', 'method': {'obj': {'cls': {'name': 'RunnableSequence', 'module': {'package_name': 'langchain_core.runnables', 'module_name': 'langchain_core.runnables.base'}, 'bases': None}, 'id': 6414884560, 'init_bindings': None}, 'name': 'invoke'}}, {'path': 'app.first', 'method': {'obj': {'cls': {'name': 'RunnableParallel', 'module': {'package_name': 'langchain_core.runnables', 'module_name': 'langchain_core.runnables.base'}, 'bases': None}, 'id': 13886132880, 'init_bindings': None}, 'name': 'invoke'}}, {'path': 'app.first.steps__.context', 'method': {'obj': {'cls': {'name': 'RunnableSequence', 'module': {'package_name': 'langchain_core.runnables', 'module_name': 'langchain_core.runnables.base'}, 'bases': None}, 'id': 6414884560, 'init_bindings': None}, 'name': 'invoke'}}, {'path': 'app.first.steps__.context.first', 'method': {'obj': {'cls': {'name': 'WithFeedbackFilterDocuments', 'module': {'package_name': 'trulens_eval.guardrails', 'module_name': 'trulens_eval.guardrails.langchain'}, 'bases': None}, 'id': 13914853328, 'init_bindings': None}, 'name': 'invoke'}}, {'path': 'app.first.steps__.context.first', 'method': {'obj': {'cls': {'name': 'WithFeedbackFilterDocuments', 'module': {'package_name': 'trulens_eval.guardrails', 'module_name': 'trulens_eval.guardrails.langchain'}, 'bases': None}, 'id': 13914853328, 'init_bindings': None}, 'name': '_get_relevant_documents'}}, {'path': 'app.first.steps__.context.first.feedback', 'method': {'obj': {'cls': {'name': 'Feedback', 'module': {'package_name': 'trulens_eval.feedback', 'module_name': 'trulens_eval.feedback.feedback'}, 'bases': None}, 'id': 13885261616, 'init_bindings': None}, 'name': '__call__'}}], 'args': {'args': ['What is Task Decomposition?', 'Fig. 10.

A MRKL system is proposed to contain a collection of \u201cexpert\u201d modules and the general-purpose LLM works as a router to route inquiries to the best suitable expert module. These modules can be neural (e.g. deep learning models) or symbolic (e.g. math calculator, currency converter, weather API).\\nThey did an experiment on fine-tuning LLM to call a calculator, using arithmetic as a test case. Their experiments showed that it was harder to solve verbal math problems than explicitly stated math problems because LLMs (7B Jurassic1-large model) failed to extract the right arguments for the basic arithmetic reliably. The results highlight when the external symbolic tools can work reliably, knowing when to and how to use the tools are crucial, determined by the LLM capability.\\nBoth TALM (Tool Augmented Language Models; Parisi et al. 2022) and Toolformer (Schick et al. 2023) fine-tune a LM to learn to use external tool APIs.

A special tag \"-task_id\" refers to the generated text image, audio and video in the dependency task with id as task_id. The task MUST be selected from the following options: {{ Available Task List }}. There is a logical relationship between tasks, please note their order. If the user input can\\'t be parsed, you need to reply empty JSON. Here are several cases for your reference: {{ Demonstrations }}. The chat history is recorded as {{ Chat History }}. From this chat history, you can find the path of the user-mentioned resources for your task planning.\\n\\n(2) Model selection: LLM distributes the tasks to expert models, where the request is framed as a multiple-choice question. LLM is presented with a list of models to choose from. Due to the limited context length, task type based filtration is needed.\\nInstruction:\\n\\nGiven the user request and the call command, the AI assistant helps the user to select a suitable model from a list of models to process the user request. The AI assistant merely outputs the model id of the most appropriate model. The output must be in a strict JSON format: \"id\": \"id\", \"reason\": \"your detail reason for the choice\".

A MRKL system is proposed to contain a collection of \u201cexpert\u201d modules and the general-purpose LLM works as a router to route inquiries to the best suitable expert module. These modules can be neural (e.g. deep learning models) or symbolic (e.g. math calculator, currency converter, weather API).\\nThey did an experiment on fine-tuning LLM to call a calculator, using arithmetic as a test case. Their experiments showed that it was harder to solve verbal math problems than explicitly stated math problems because LLMs (7B Jurassic1-large model) failed to extract the right arguments for the basic arithmetic reliably. The results highlight when the external symbolic tools can work reliably, knowing when to and how to use the tools are crucial, determined by the LLM capability.\\nBoth TALM (Tool Augmented Language Models; Parisi et al. 2022) and Toolformer (Schick et al. 2023) fine-tune a LM to learn to use external tool APIs. The dataset is expanded based on whether a newly added API call annotation can improve the quality of model outputs. See more details in the \u201cExternal APIs\u201d section of Prompt Engineering.\\nChatGPT Plugins and OpenAI API function calling are good examples of LLMs augmented with tool use capability working in practice. The collection of tool APIs can be provided by other developers (as in Plugins) or self-defined (as in function calls).\\nHuggingGPT (Shen et al. 2023) is a framework to use ChatGPT as the task planner to select models available in HuggingFace platform according to the model descriptions and summarize the response based on the execution results.\\n\\nFig. 11. Illustration of how HuggingGPT works. (Image source: Shen et al. 2023)\\nThe system comprises of 4 stages:\\n(1) Task planning: LLM works as the brain and parses the user requests into multiple tasks. There are four attributes associated with each task: task type, ID, dependencies, and arguments. They use few-shot examples to guide LLM to do task parsing and planning.\\nInstruction:\\n\\nThe AI assistant can parse user input to several tasks: [{\"task\": task, \"id\", task_id, \"dep\": dependency_task_ids, \"args\": {\"text\": text, \"image\": URL, \"audio\": URL, \"video\": URL}}]. The \"dep\" field denotes the id of the previous task which generates a new resource that the current task relies on. A special tag \"-task_id\" refers to the generated text image, audio and video in the dependency task with id as task_id. The task MUST be selected from the following options: {{ Available Task List }}. There is a logical relationship between tasks, please note their order. If the user input can\\'t be parsed, you need to reply empty JSON. Here are several cases for your reference: {{ Demonstrations }}. The chat history is recorded as {{ Chat History }}. From this chat history, you can find the path of the user-mentioned resources for your task planning.\\n\\n(2) Model selection: LLM distributes the tasks to expert models, where the request is framed as a multiple-choice question. LLM is presented with a list of models to choose from. Due to the limited context length, task type based filtration is needed.\\nInstruction:\\n\\nGiven the user request and the call command, the AI assistant helps the user to select a suitable model from a list of models to process the user request. The AI assistant merely outputs the model id of the most appropriate model. The output must be in a strict JSON format: \"id\": \"id\", \"reason\": \"your detail reason for the choice\". We have a list of models for you to choose from {{ Candidate Models }}. Please select one model from the list.', 'metadata': {'source': 'https://lilianweng.github.io/posts/2023-06-23-agent/'}, 'type': 'Document'}, {'page_content': \"(3) Task execution: Expert models execute on the specific tasks and log results.\\nInstruction:\\n\\nWith the input and the inference results, the AI assistant needs to describe the process and results. The previous stages can be formed as - User Input: {{ User Input }}, Task Planning: {{ Tasks }}, Model Selection: {{ Model Assignment }}, Task Execution: {{ Predictions }}. You must first answer the user's request in a straightforward manner. Then describe the task process and show your analysis and model inference results to the user in the first person. If inference results contain a file path, must tell the user the complete file path.\\n\\n(4) Response generation: LLM receives the execution results and provides summarized results to users.\\nTo put HuggingGPT into real world usage, a couple challenges need to solve: (1) Efficiency improvement is needed as both LLM inference rounds and interactions with other models slow down the process; (2) It relies on a long context window to communicate over complicated task content; (3) Stability improvement of LLM outputs and external model services.\\nAPI-Bank (Li et al. 2023) is a benchmark for evaluating the performance of tool-augmented LLMs. It contains 53 commonly used API tools, a complete tool-augmented LLM workflow, and 264 annotated dialogues that involve 568 API calls. The selection of APIs is quite diverse, including search engines, calculator, calendar queries, smart home control, schedule management, health data management, account authentication workflow and more. Because there are a large number of APIs, LLM first has access to API search engine to find the right API to call and then uses the corresponding documentation to make a call.\\n\\nFig. 12. Pseudo code of how LLM makes an API call in API-Bank. (Image source: Li et al. 2023)\\nIn the API-Bank workflow, LLMs need to make a couple of decisions and at each step we can evaluate how accurate that decision is. Decisions include:\\n\\nWhether an API call is needed.\\nIdentify the right API to call: if not good enough, LLMs need to iteratively modify the API inputs (e.g. deciding search keywords for Search Engine API).\\nResponse based on the API results: the model can choose to refine and call again if results are not satisfied.\\n\\nThis benchmark evaluates the agent\u2019s tool use capabilities at three levels:\\n\\nLevel-1 evaluates the ability to call the API. Given an API\u2019s description, the model needs to determine whether to call a given API, call it correctly, and respond properly to API returns.\\nLevel-2 examines the ability to retrieve the API. The model needs to search for possible APIs that may solve the user\u2019s requirement and learn how to use them by reading documentation.\\nLevel-3 assesses the ability to plan API beyond retrieve and call. Given unclear user requests (e.g. schedule group meetings, book flight/hotel/restaurant for a trip), the model may have to conduct multiple API calls to solve it.\\n\\nCase Studies#\\nScientific Discovery Agent#\\nChemCrow (Bran et al. 2023) is a domain-specific example in which LLM is augmented with 13 expert-designed tools to accomplish tasks across organic synthesis, drug discovery, and materials design. The workflow, implemented in LangChain, reflects what was previously described in the ReAct and MRKLs and combines CoT reasoning with tools relevant to the tasks:\\n\\nThe LLM is provided with a list of tool names, descriptions of their utility, and details about the expected input/output.\\nIt is then instructed to answer a user-given prompt using the tools provided when necessary. The instruction suggests the model to follow the ReAct format - Thought, Action, Action Input, Observation.\", 'metadata': {'source': 'https://lilianweng.github.io/posts/2023-06-23-agent/'}, 'type': 'Document'}, {'page_content': 'Fig. 6. Illustration of how Algorithm Distillation (AD) works. (Image source: Laskin et al. 2023).\\nThe paper hypothesizes that any algorithm that generates a set of learning histories can be distilled into a neural network by performing behavioral cloning over actions. The history data is generated by a set of source policies, each trained for a specific task. At the training stage, during each RL run, a random task is sampled and a subsequence of multi-episode history is used for training, such that the learned policy is task-agnostic.\\nIn reality, the model has limited context window length, so episodes should be short enough to construct multi-episode history. Multi-episodic contexts of 2-4 episodes are necessary to learn a near-optimal in-context RL algorithm. The emergence of in-context RL requires long enough context.\\nIn comparison with three baselines, including ED (expert distillation, behavior cloning with expert trajectories instead of learning history), source policy (used for generating trajectories for distillation by UCB), RL^2 (Duan et al. 2017; used as upper bound since it needs online RL), AD demonstrates in-context RL with performance getting close to RL^2 despite only using offline RL and learns much faster than other baselines. When conditioned on partial training history of the source policy, AD also improves much faster than ED baseline.\\n\\nFig. 7.

I\u2019ve learned a lot about the human brain and data structure for fast MIPS in my conversations with ChatGPT.)\\nTypes of Memory#\\nMemory can be defined as the processes used to acquire, store, retain, and later retrieve information. There are several types of memory in human brains.\\n\\n\\nSensory Memory: This is the earliest stage of memory, providing the ability to retain impressions of sensory information (visual, auditory, etc) after the original stimuli have ended. Sensory memory typically only lasts for up to a few seconds.

An agent needs to know what they are and plan ahead.\\nTask Decomposition#\\nChain of thought (CoT; Wei et al. 2022) has become a standard prompting technique for enhancing model performance on complex tasks. The model is instructed to \u201cthink step by step\u201d to utilize more test-time computation to decompose hard tasks into smaller and simpler steps. CoT transforms big tasks into multiple manageable tasks and shed lights into an interpretation of the model\u2019s thinking process.\\nTree of Thoughts (Yao et al. 2023) extends CoT by exploring multiple reasoning possibilities at each step. It first decomposes the problem into multiple thought steps and generates multiple thoughts per step, creating a tree structure. The search process can be BFS (breadth-first search) or DFS (depth-first search) with each state evaluated by a classifier (via a prompt) or majority vote.\\nTask decomposition can be done (1) by LLM with simple prompting like \"Steps for XYZ.\\\\n1.\", \"What are the subgoals for achieving XYZ?\", (2) by using task-specific instructions; e.g. \"Write a story outline.\" for writing a novel, or (3) with human inputs.\\nAnother quite distinct approach, LLM+P (Liu et al. 2023), involves relying on an external classical planner to do long-horizon planning. This approach utilizes the Planning Domain Definition Language (PDDL) as an intermediate interface to describe the planning problem. In this process, LLM (1) translates the problem into \u201cProblem PDDL\u201d, then (2) requests a classical planner to generate a PDDL plan based on an existing \u201cDomain PDDL\u201d, and finally (3) translates the PDDL plan back into natural language. Essentially, the planning step is outsourced to an external tool, assuming the availability of domain-specific PDDL and a suitable planner which is common in certain robotic setups but not in many other domains.\\nSelf-Reflection#\\nSelf-reflection is a vital aspect that allows autonomous agents to improve iteratively by refining past action decisions and correcting previous mistakes. It plays a crucial role in real-world tasks where trial and error are inevitable.\\nReAct (Yao et al. 2023) integrates reasoning and acting within LLM by extending the action space to be a combination of task-specific discrete actions and the language space. The former enables LLM to interact with the environment (e.g. use Wikipedia search API), while the latter prompting LLM to generate reasoning traces in natural language.\\nThe ReAct prompt template incorporates explicit steps for LLM to think, roughly formatted as:\\nThought: ...\\nAction: ...\\nObservation: ...\\n...

The selection of APIs is quite diverse, including search engines, calculator, calendar queries, smart home control, schedule management, health data management, account authentication workflow and more.

Pseudo code of how LLM makes an API call in API-Bank.

Decisions include:\\n\\nWhether an API call is needed.\\nIdentify the right API to call: if not good enough, LLMs need to iteratively modify the API inputs (e.g. deciding search keywords for Search Engine API).\\nResponse based on the API results: the model can choose to refine and call again if results are not satisfied.\\n\\nThis benchmark evaluates the agent\u2019s tool use capabilities at three levels:\\n\\nLevel-1 evaluates the ability to call the API.

The history data is generated by a set of source policies, each trained for a specific task. At the training stage, during each RL run, a random task is sampled and a subsequence of multi-episode history is used for training, such that the learned policy is task-agnostic.\\nIn reality, the model has limited context window length, so episodes should be short enough to construct multi-episode history. Multi-episodic contexts of 2-4 episodes are necessary to learn a near-optimal in-context RL algorithm. The emergence of in-context RL requires long enough context.\\nIn comparison with three baselines, including ED (expert distillation, behavior cloning with expert trajectories instead of learning history), source policy (used for generating trajectories for distillation by UCB), RL^2 (Duan et al. 2017; used as upper bound since it needs online RL), AD demonstrates in-context RL with performance getting close to RL^2 despite only using offline RL and learns much faster than other baselines. When conditioned on partial training history of the source policy, AD also improves much faster than ED baseline.\\n\\nFig. 7.

A MRKL system is proposed to contain a collection of \u201cexpert\u201d modules and the general-purpose LLM works as a router to route inquiries to the best suitable expert module. These modules can be neural (e.g. deep learning models) or symbolic (e.g. math calculator, currency converter, weather API).\\nThey did an experiment on fine-tuning LLM to call a calculator, using arithmetic as a test case. Their experiments showed that it was harder to solve verbal math problems than explicitly stated math problems because LLMs (7B Jurassic1-large model) failed to extract the right arguments for the basic arithmetic reliably. The results highlight when the external symbolic tools can work reliably, knowing when to and how to use the tools are crucial, determined by the LLM capability.\\nBoth TALM (Tool Augmented Language Models; Parisi et al. 2022) and Toolformer (Schick et al. 2023) fine-tune a LM to learn to use external tool APIs.

There are four attributes associated with each task: task type, ID, dependencies, and arguments. They use few-shot examples to guide LLM to do task parsing and planning.\\nInstruction:\\n\\nThe AI assistant can parse user input to several tasks: [{\"task\": task, \"id\", task_id, \"dep\": dependency_task_ids, \"args\": {\"text\": text, \"image\": URL, \"audio\": URL, \"video\": URL}}]. The \"dep\" field denotes the id of the previous task which generates a new resource that the current task relies on. A special tag \"-task_id\" refers to the generated text image, audio and video in the dependency task with id as task_id. The task MUST be selected from the following options: {{ Available Task List }}. There is a logical relationship between tasks, please note their order. If the user input can\\'t be parsed, you need to reply empty JSON. Here are several cases for your reference: {{ Demonstrations }}. The chat history is recorded as {{ Chat History }}. From this chat history, you can find the path of the user-mentioned resources for your task planning.\\n\\n(2) Model selection: LLM distributes the tasks to expert models, where the request is framed as a multiple-choice question. LLM is presented with a list of models to choose from. Due to the limited context length, task type based filtration is needed.\\nInstruction:\\n\\nGiven the user request and the call command, the AI assistant helps the user to select a suitable model from a list of models to process the user request.

In this quickstart you will create a simple LCEL Chain and learn how to log it and get feedback on an LLM response.
For evaluation, we will leverage the RAG triad of groundedness, context relevance and answer relevance.

Wouldn't it be great if we could automatically filter out context chunks with relevance scores below 0.5?
We can do so with the TruLens guardrail, WithFeedbackFilterNodes. All we have to do is use the method of_query_engine to create a new filtered retriever, passing in the original retriever along with the feedback function and threshold we want to use.

In this quickstart you will create a simple Llama Index app and learn how to log it and get feedback on an LLM response.
You'll also learn how to use feedbacks for guardrails, via filtering retrieved context.
For evaluation, we will leverage the RAG triad of groundedness, context relevance and answer relevance.

Evaluating LLM applications often requires access to the internals of an app, such as retrieved context. To gain access to these internals, TruLens provides the instrument method. In cases where you have access to the classes and methods required, you can add the @instrument decorator to any method you wish to instrument. See a usage example below:
"},{"location":"trulens_eval/tracking/instrumentation/#using-the-instrument-decorator","title":"Using the

In cases you do not have access to a class to make the necessary decorations for tracking, you can instead use one of the static methods of instrument, for example, the alterative for making sure the custom retriever gets instrumented is via instrument.method. See a usage example below:

To properly evaluate LLM apps we often need to point our evaluation at an internal step of our application, such as the retreived context. Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LlamaIndex applications where the source nodes are used, select_context can be used to access the retrieved text for evaluation.

TruLens provides TruLlama, a deep integration with LlamaIndex to allow you to inspect and evaluate the internals of your application built using LlamaIndex. This is done through the instrumentation of key LlamaIndex classes and methods. To see all classes and methods instrumented, see Appendix: LlamaIndex Instrumented Classes and Methods.
In addition to the default instrumentation, TruChain exposes the select_context and select_source_nodes methods for evaluations that require access to retrieved context or source nodes. Exposing these methods bypasses the need to know the json structure of your app ahead of time, and makes your evaluations re-usable across different apps.

TruLens provides TruRails, an integration with NeMo Guardrails apps to allow you to inspect and evaluate the internals of your application built using NeMo Guardrails. This is done through the instrumentation of key NeMo Guardrails classes. To see a list of classes instrumented, see Appendix: Instrumented Nemo Classes and Methods.
In addition to the default instrumentation, TruRails exposes the select_context method for evaluations that require access to retrieved context. Exposing select_context bypasses the need to know the json structure of your app ahead of time, and makes your evaluations re-usable across different apps.

"},{"location":"trulens_explain/attribution_parameterization/#basic-definitions-and-terminology","title":"Basic Definitions and Terminology","text":"
What is a tensor? A tensor is a multidimensional object that can be model inputs, or layer activations.
What is a layer? A layer is a set of neurons that can be thought of as a function on input tensors. Layer inputs are tensors. Layer outputs are modified tensors.
What are anchors? Anchors are ways of specifying which tensors you want. You may want the input tensor of a layer, or the output tensor of a layer.
E.g. Say you have a concat layer and you want to explain the 2 concatenated tensors. The concat operation is not usually a layer tracked by the model. If you try the 'in' anchor of the layer after the operation, you get a single tensor with all the information you need.
What is a Quantity of Interest (QoI)? A QoI is a scalar number that is being explained.
E.g. With saliency maps, you get dx/dy (i.e. the effect of input on output). y in this case is the QoI scalar. It is usually the output of a neuron, but could be a sum of multiple neurons.
What is an attribution? An attribution is a numerical value associated with every element in a tensor that explains a QoI.
E.g. With saliency maps, you get dx/dy. x is the associated tensor. The entirety of dx/dy is the explanation.
What are cuts? Cuts are tensors that cut a network into two parts. They are composed of a layer and an anchor.
What are slices? Slices are two cuts leaving a slice of the network. The attribution will be on the first cut, explaining the QoI on the second cut of the slice.
E.g. With saliency maps, the TruLens slice would be AttributionCut: Cut(x) to QoICut: Cut(y), denoted by Slice(Cut(x),Cut(y)).

Use case: Explain something that isn't the default model output.
E.g. If you want to explain a logit layer instead of the probit (final) layer.

- For PyTorch models, model inputs are not tensors, so you'd want the 'in' anchor of the first layer.
Cuts needed: As you want to know the affect of some other layer rather than the input layer, you need to customize the attribution cut.

What is a Distribution of Interest (DoI)?
The distribution of interest is a concept of aggregating attributions over a sample or distribution.
- Grad-CAM (Paper, GitHub, Docs) does this over a Gaussian distribution of inputs.
- Shapley values (GitHub, Docs) do this over different background data.
- Integrated Gradients (Paper, Tutorial) do this over an interpolation from a baseline to the input.
How does this relate to the Attribution Cut?
The sample or distributions are taken at a place that is humanly considered the input, even if this differs from the programmatic model input.
For attributions, all parts of a network can have an attribution towards the QoI. The most common use case is to explain the tensors that are also humanly considered the input (which is where the DoI occurs).
How does this relate to the Baseline Cut?
The Baseline Cut is only applicable to the Integrated Gradients method. It is also only needed when there is no mathematical way to interpolate the baseline to the input.
E.g. if the input is 'Hello', but the baseline is a '[MASK]' token, we cannot interpolate that. We define the baseline at the token layer, but interpolate on a numeric layer like the embeddings.

Attribution methods quantitatively measure the contribution of each of a function's individual inputs to its output. Gradient-based attribution methods compute the gradient of a model with respect to its inputs to describe how important each input is towards the output prediction. These methods can be applied to assist in explaining deep networks.
TruLens provides implementations of several such techniques, found in this package.

attributions(\n *model_args: ArgsLike, **model_kwargs: KwargsLike\n) -> Union[\n TensorLike,\n ArgsLike[TensorLike],\n ArgsLike[ArgsLike[TensorLike]],\n]\n
Returns attributions for the given input. Attributions are in the same shape as the layer that attributions are being generated for.
The numeric scale of the attributions will depend on the specific implementations of the Distribution of Interest and Quantity of Interest. However it is generally related to the scale of gradients on the Quantity of Interest.
For example, Integrated Gradients uses the linear interpolation Distribution of Interest which subsumes the completeness axiom which ensures the sum of all attributions of a record equals the output determined by the Quantity of Interest on the same record.
The Point Distribution of Interest will be determined by the gradient at a single point, thus being a good measure of model sensitivity.

This should represent the records to obtain attributions for, assumed to be a batched input. if self.model supports evaluation on data tensors, the appropriate tensor type may be used (e.g., Pytorch models may accept Pytorch tensors in addition to np.ndarrays). The shape of the inputs must match the input shape of self.model.

Internal attributions parameterized by a slice, quantity of interest, and distribution of interest.
The slice specifies the layers at which the internals of the model are to be exposed; it is represented by two cuts, which specify the layer the attributions are assigned to and the layer from which the quantity of interest is derived. The Quantity of Interest (QoI) is a function of the output specified by the slice that determines the network output behavior that the attributions are to describe.

A Quantity of Interest (QoI) is a function of the output that determines the network output behavior that the attributions describe.
The quantity of interest lets us specify what we want to explain. Often, this is the output of the network corresponding to a particular class, addressing, e.g., \"Why did the model classify a given image as a car?\" However, we could also consider various combinations of outputs, allowing us to ask more specific questions, such as, \"Why did the model classify a given image as a sedan and not a convertible?\" The former may highlight general \u201ccar features,\u201d such as tires, while the latter (called a comparative explanation) might focus on the roof of the car, a \u201ccar feature\u201d not shared by convertibles.

'unsigned_max': normalizes the attributions to the range [-1, 1] by dividing the attributions by the maximum absolute attribution value.'unsigned_max_positive_centered': same as above, but scales the values to the range [0, 1], with negative scores less than 0.5 and positive scores greater than 0.5. 'magnitude_max': takes the absolute value of the attributions, then normalizes the attributions to the range [0, 1] by dividing by the maximum absolute attribution value.'magnitude_sum': takes the absolute value of the attributions, then scales them such that they sum to 1. If this option is used, each channel is normalized separately, such that each channel sums to 1.'signed_max': normalizes the attributions to the range [-1, 1] by dividing the positive values by the maximum positive attribution value and the negative values by the minimum negative attribution value.'signed_max_positive_centered': same as above, but scales the values to the range [0, 1], with negative scores less than 0.5 and positive scores greater than 0.5.'signed_sum': scales the positive attributions such that they sum to 1 and the negative attributions such that they scale to -1. If this option is used, each channel is normalized separately.'01': normalizes the attributions to the range [0, 1] by subtracting the minimum attribution value then dividing by the maximum attribution value.'unnormalized': leaves the attributions unaffected.
If None, defaults to the value supplied to the constructor.
DEFAULT: None
blur Gives the radius of a Gaussian blur to be applied to the attributions before visualizing. This can be used to help focus on salient regions rather than specific salient pixels. If None, defaults to the value supplied to the constructor.
DEFAULT: None
cmap matplotlib.colors.Colormap | str, optional Colormap or name of a Colormap to use for the visualization. If None, defaults to the value supplied to the constructor.
DEFAULT: None
RETURNS DESCRIPTION

PARAMETER DESCRIPTION
blur Gives the radius of a Gaussian blur to be applied to the attributions before visualizing. This can be used to help focus on salient regions rather than specific salient pixels.
DEFAULT: 5.0
threshold Value in the range [0, 1]. Attribution values at or below the percentile given by threshold (after normalization, blurring, etc.) will be masked.
DEFAULT: 0.5
masked_opacity Value in the range [0, 1] specifying the opacity for the parts of the image that are masked.

use_attr_as_opacity If True, instead of using threshold and masked_opacity, the opacity of each pixel is given by the 0-1-normalized attribution value.
DEFAULT: False
positive_only If True, only pixels with positive attribution will be unmasked (or given nonzero opacity when use_attr_as_opacity is true).

DEFAULT: None
agg_fn Function with which to aggregate the remaining dimensions (except the batch dimension) in order to get a single scalar value for each channel; If None, a sum over each neuron in the channel will be taken. This argument is not used when the channels are scalars, e.g., for dense layers.
DEFAULT: None
doi The distribution of interest to use when computing the input attributions towards the specified channel. If None, PointDoI will be used.
