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).

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.

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:
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:

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.
The instrumented versions of functions/methods record the inputs/outputs and some additional data (see 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.
The arguments to a call and its return are converted to json using the same tools as App Data (see above).
"},{"location":"trulens_eval/api/instruments/#trulens_eval.instruments--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).
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:
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. 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.
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.
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:
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.
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.

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?

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.
Try to have all internals be async but for users we may expose sync versions via the sync method. If internals are async and don't need exposure, don't need to provide a synced version.

This is a (likely incomplete) list of hacks present in the trulens_eval library. They are likely a source of debugging problems so ideally they can be addressed/removed in time. This document is to serve as a warning in the meantime and a resource for hard-to-debug issues when they arise.
In notes below, \"HACK###\" can be used to find places in the code where the hack lives.
"},{"location":"trulens_eval/contributing/techdebt/#stack-inspecting","title":"Stack inspecting","text":"See instruments.py docstring for discussion why these are done.
We inspect the call stack in process of tracking method invocation. It may be possible to replace this with contextvars.
\"HACK012\" -- In the optional imports scheme, we have to make sure that imports that happen from outside of trulens raise exceptions instead of producing dummies without raising exceptions.
See instruments.py docstring for discussion why these are done.
We override and wrap methods from other libraries to track their invocation or API use. Overriding for tracking invocation is done in the base instruments.py:Instrument class while for tracking costs are in the base Endpoint class.
\"HACK009\" -- Cannot reliably determine whether a function referred to by an object that implements __call__ has been instrumented. Hacks to avoid warnings about lack of instrumentation.
See instruments.py docstring for discussion why these are done.
\"HACK002\" -- We override ThreadPoolExecutor in concurrent.futures.
\"HACK007\" -- We override Thread in threading.
trace_method decorator in llama_index does not preserve function signatures; we hack it so that it does.~~ Fixed as of llama_index 0.9.26 or near there.langchain_core.runnables.config.ContextThreadPoolExecutor so it uses our thread starter.\"HACK006\" -- endpoint needs to be added as a keyword arg with default value in some __init__ because pydantic overrides signature without default value otherwise.
\"HACK005\" -- model_validate inside WithClassInfo is implemented in decorated method because pydantic doesn't call it otherwise. It is uncertain whether this is a pydantic bug.
We dump attributes marked to be excluded by pydantic except our own classes. This is because some objects are of interest despite being marked to exclude. Example: RetrievalQA.retriever in langchain.
\"HACK004\" -- Outdated, need investigation whether it can be removed.
~~async/sync code duplication -- Many of our methods are almost identical duplicates due to supporting both async and synced versions. Having trouble with a working approach to de-duplicated the identical code.~~ Fixed. See utils/asynchro.py.
~~\"HACK008\" -- async generator -- Some special handling is used for tracking costs when async generators are involved. See feedback/provider/endpoint/base.py.~~ Fixed in endpoint code.
\"HACK010\" -- cannot tell whether something is a coroutine and need additional checks in sync/desync.
\"HACK011\" -- older pythons don't allow use of Future as a type constructor in annotations. We define a dummy type Future in older versions of python to circumvent this but have to selectively import it to make sure type checking and mkdocs is done right.
\"HACK012\" -- same but with Queue.
Similarly, we define NoneType for older python versions.
\"HACK013\" -- when using from __future__ import annotations for more convenient type annotation specification, one may have to call pydantic's BaseModel.model_rebuild after all types references in annotations in that file have been defined for each model class that uses type annotations that reference types defined after its own definition (i.e. \"forward refs\").

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\nReturns:
{'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}\nOptionally, 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\nReturns:
{'Code implementation': [\n 'What are the subcategories of sensory memory?',\n 'What is the capacity of short-term memory according to Miller (1956)?'\n ],\n 'Short term memory limitations': [\n 'What is the duration of sensory memory?',\n 'What are the limitations of short-term memory in terms of context capacity?'\n ],\n 'Planning and task decomposition challenges': [\n 'How long does sensory memory typically last?',\n 'What are the challenges in long-term planning and task decomposition?'\n ]\n}\nIn combination with record metadata logging, this gives you the ability to understand the performance of your application across different prompt categories.
with tru_recorder as recording:\n for category in test_set:\n recording.record_metadata=dict(prompt_category=category)\n test_prompts = test_set[category]\n for test_prompt in test_prompts:\n llm_response = rag_chain.invoke(test_prompt)\nThis is a section heading page.

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.

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.

You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a test set.
However unlike traditional machine learning, user feedback or any \"ground truth\" is largely unavailable. Without ground truth on which to compute metrics on our LLM apps, we can turn to feedback functions as a way to compute metrics for LLM apps.
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 measures the performance of your app, on your data, for your users.
Last, feedback functions are flexible. They can be implemented with any model on the back-end. This includes rule-based systems, smaller models tailored to a particular task, or carefully prompted large language models.
"},{"location":"trulens_eval/evaluation/feedback_functions/anatomy/","title":"Anatomy of Feedback Functions","text":"The Feedback class contains the starting point for feedback function specification and evaluation. A typical use-case looks like this:
from trulens_eval import OpenAI\n\nopenai = OpenAI(model_engine=\"gpt-3.5-turbo\")\n\nf_relevance = Feedback(openai.relevance).on_input_output()\nThe components of this specifications are:
Feedback Providers -- The provider is the back-end on which a given feedback function is run.' Multiple underlying models are available through each provider, such as GPT-4 or Llama-2. In many, but not all cases, the feedback implementation is shared across providers (such as with LLM-based evaluations).
Feedback implementations -- openai.relevance is 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 relevance(self, prompt: str, response: str) -> float:\nThat is, relevance is a plain python method that accepts the prompt and response, both strings, and produces a float (assumed to be between 0.0 and 1.0).
Feedback constructor -- The line Feedback(openai.relevance) constructs a Feedback object with a feedback implementation.
Argument specification -- The next line, 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 relevance (prompt and response) 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.

"},{"location":"trulens_eval/evaluation/feedback_functions/guide/#llama_index-specific-selectors","title":"llama_index-specific selectors","text":"TruLlama.select_source_nodes() -- outputs the selector of the source documents part of the engine output.For more advanced control on the feedback function operation, we allow data selection and aggregation. Consider this feedback example:
f_qs_relevance = Feedback(openai.qs_relevance)\n .on_input()\n .on(Select.Record.app.combine_docs_chain._call.args.inputs.input_documents[:].page_content)\n .aggregate(numpy.min)\n\n# Implementation signature:\n# def qs_relevance(self, question: str, statement: str) -> float:\nArgument Selection specification -- Where we previously set, on_input_output , the on(Select...) line enables specification of where the statement argument to the implementation comes from. The form of the specification will be discussed in further details in the Specifying Arguments section.
Aggregation specification -- The last line aggregate(numpy.min) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type. The input to aggregate must be a method which can be imported globally. This requirement is further elaborated in the next section. This function is called on the float results of feedback function evaluations to produce a single float. The default is numpy.mean.
The result of these lines is that f_qs_relevance can be now be run on app/records and will automatically select the specified components of those apps/records:
record: Record = ...\napp: App = ...\n\nfeedback_result: FeedbackResult = f_qs_relevance.run(app=app, record=record)\nThe object can also be provided to an app wrapper for automatic evaluation:
app: App = tru.Chain(...., feedbacks=[f_qs_relevance])\nThe function or method provided to the Feedback constructor is the implementation of the feedback function which does the actual work of producing a float indicating some quantity of interest.
Note regarding FeedbackMode.DEFERRED -- Any function or method (not static or class methods presently supported) can be provided here but there are additional requirements if your app uses the \"deferred\" feedback evaluation mode (when feedback_mode=FeedbackMode.DEFERRED are specified to app constructor). In those cases the callables must be functions or methods that are importable (see the next section for details). The function/method performing the aggregation has the same requirements.
If using deferred evaluation, the feedback function implementations and aggregation implementations must be functions or methods from a Provider subclass that is importable. That is, the callables must be accessible were you to evaluate this code:
from somepackage.[...] import someproviderclass\nfrom somepackage.[...] import somefunction\n\n# [...] means optionally further package specifications\n\nprovider = someproviderclass(...) # constructor arguments can be included\nfeedback_implementation1 = provider.somemethod\nfeedback_implementation2 = somefunction\nFor provided feedback functions, somepackage is trulens_eval.feedback and someproviderclass is OpenAI or one of the other Provider subclasses. Custom feedback functions likewise need to be importable functions or methods of a provider subclass that can be imported. Critically, functions or classes defined locally in a notebook will not be importable this way.
The mapping between app/records to feedback implementation arguments is specified by the on... methods of the Feedback objects. The general form is:
feedback: Feedback = feedback.on(argname1=selector1, argname2=selector2, ...)\nThat is, Feedback.on(...) returns a new Feedback object with additional argument mappings, the source of argname1 is selector1 and so on for further argument names. The types of selector1 is JSONPath which we elaborate on in the \"Selector Details\".
If argument names are ommitted, they are taken from the feedback function implementation signature in order. That is,
Feedback(...).on(argname1=selector1, argname2=selector2)\nand
Feedback(...).on(selector1, selector2)\nare equivalent assuming the feedback implementation has two arguments, argname1 and argname2, in that order.
Feedback implementations are simple callables that can be run on any arguments matching their signatures. However, once wrapped with Feedback, they are meant to be run on outputs of app evaluation (the \"Records\"). Specifically, Feedback.run has this definition:
def run(self, \n app: Union[AppDefinition, JSON], \n record: Record\n) -> FeedbackResult:\nThat is, the context of a Feedback evaluation is an app (either as AppDefinition or a JSON-like object) and a Record of the execution of the aforementioned app. Both objects are indexable using \"Selectors\". By indexable here we mean that their internal components can be specified by a Selector and subsequently that internal component can be extracted using that selector. Selectors for Feedback start by specifying whether they are indexing into an App or a Record via the __app__ and __record__ special attributes (see Selectors section below).
Apps and Records will be converted to JSON-like structures representing their callstack.
Selectors are of type JSONPath defined in utils/serial.py help specify paths into JSON-like structures (enumerating Record or App contents).
In most cases, the Select object produces only a single item but can also address multiple items.
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()\nIf a selector looks like the below
Select.Record.app.combine_documents_chain._call\nIt can be accessed via the JSON-like via
json_like['app']['combine_documents_chain']['_call']\nThe 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.
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.

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.
Feedback functions are implemented in collections in instances of the Provider class. There are three categories of such providers as well as combination providers that make use of one or more of these providers to offer additional feedback functions based capabilities of the constituent providers.

Feedback functions are organized by model provider into Provider classes.
The process for adding new feedback functions is:
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.

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()\non_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":"For more advanced control on the feedback function operation, we allow data selection and aggregation. Consider this feedback example:
f_qs_relevance = Feedback(openai.qs_relevance)\n .on_input()\n .on(Select.Record.app.combine_docs_chain._call.args.inputs.input_documents[:].page_content)\n .aggregate(numpy.min)\n\n# Implementation signature:\n# def qs_relevance(self, question: str, statement: str) -> float:\nArgument Selection specification -- Where we previously set, on_input_output , the on(Select...) line enables specification of where the statement argument to the implementation comes from. The form of the specification will be discussed in further details in the Specifying Arguments section.
Aggregation specification -- The last line aggregate(numpy.min) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type. The input to aggregate must be a method which can be imported globally. This requirement is further elaborated in the next section. This function is called on the float results of feedback function evaluations to produce a single float. The default is numpy.mean.
The result of these lines is that f_qs_relevance can be now be run on app/records and will automatically select the specified components of those apps/records:
record: Record = ...\napp: App = ...\n\nfeedback_result: FeedbackResult = f_qs_relevance.run(app=app, record=record)\nThe object can also be provided to an app wrapper for automatic evaluation:
app: App = tru.Chain(..., feedbacks=[f_qs_relevance])\nThe function or method provided to the Feedback constructor is the implementation of the feedback function which does the actual work of producing a float indicating some quantity of interest.
Note regarding FeedbackMode.DEFERRED -- Any function or method (not static or class methods presently supported) can be provided here but there are additional requirements if your app uses the \"deferred\" feedback evaluation mode (when feedback_mode=FeedbackMode.DEFERRED are specified to app constructor). In those cases the callables must be functions or methods that are importable (see the next section for details). The function/method performing the aggregation has the same requirements.
If using deferred evaluation, the feedback function implementations and aggregation implementations must be functions or methods from a Provider subclass that is importable. That is, the callables must be accessible were you to evaluate this code:
from somepackage.[...] import someproviderclass\nfrom somepackage.[...] import somefunction\n\n# [...] means optionally further package specifications\n\nprovider = someproviderclass(...) # constructor arguments can be included\nfeedback_implementation1 = provider.somemethod\nfeedback_implementation2 = somefunction\nFor provided feedback functions, somepackage is trulens_eval.feedback and someproviderclass is OpenAI or one of the other Provider subclasses. Custom feedback functions likewise need to be importable functions or methods of a provider subclass that can be imported. Critically, functions or classes defined locally in a notebook will not be importable this way.
The mapping between app/records to feedback implementation arguments is specified by the on... methods of the Feedback objects. The general form is:
feedback: Feedback = feedback.on(argname1=selector1, argname2=selector2, ...)\nThat is, Feedback.on(...) returns a new Feedback object with additional argument mappings, the source of argname1 is selector1 and so on for further argument names. The types of selector1 is JSONPath which we elaborate on in the \"Selector Details\".
If argument names are ommitted, they are taken from the feedback function implementation signature in order. That is,
Feedback(...).on(argname1=selector1, argname2=selector2)\nand
Feedback(...).on(selector1, selector2)\nare equivalent assuming the feedback implementation has two arguments, argname1 and argname2, in that order.
Apps and Records will be converted to JSON-like structures representing their callstack.
Selectors are of type JSONPath defined in utils/serial.py help specify paths into JSON-like structures (enumerating Record or App contents).
In most cases, the Select object produces only a single item but can also address multiple items.
You can access the JSON structure with with_record methods and then calling layout_calls_as_app.
for example
rag_chain.invoke(\"What is Task Decomposition?\")\n\nfrom trulens_eval import TruChain\ntru_recorder = TruChain(\n rag_chain,\n app_id='Chain1_ChatApplication')\n\nresponse, tru_record = tru_recorder.with_record(rag_chain.invoke, \"What is Task Decomposition?\")\njson_like = tru_record.layout_calls_as_app()\nIf a selector looks like the below
Select.Record.app.combine_documents_chain._call\nIt can be accessed via the JSON-like via
json_like['app']['combine_documents_chain']['_call']\nThis structure can also be seen in the TruLens Evaluations UI by clicking on a component of interest in 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.
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.

tru = ... # your app, extending App\nprint(tru.dict())\nWhen 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.

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:

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>\")\nNote
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)\nIf 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\nWhen 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\"\nNow 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]\nAlternatively, 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()\nTo 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)\nNow 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)\nThen, 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)\nTo finally ingest the record and run feedbacks, we can use add_record.
for record in data:\n virtual_recorder.add_record(rec)\nTo 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)\nThe VirtualApp metadata can also be appended.
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024\nThis 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\"\nThe primary method for evlauating 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:\nOnce 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])\nNow 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?\")\nIn 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 )\nHere 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.These installation instructions assume that you have conda installed and added to your path.

Building and Evaluating a prototype RAG
Reducing Hallucination for RAGs
The AI should not be offensive or discriminatory, either directly or through subtext or bias.
When asked to aid in a dangerous act (e.g. building a bomb), the AI should politely refuse. Ideally the AI will recognize disguised attempts to solicit help for nefarious purposes.
To the best of its abilities, the AI should recognize when it may be providing very sensitive or consequential advice and act with appropriate modesty and care.
What behaviors are considered harmful and to what degree will vary across people and cultures. It will also be context-dependent, i.e. it will depend on the nature of the use.

Harmless Evaluation for LLM apps
Improving Harmlessness for LLM apps
The AI should make a clear attempt to perform the task or answer the question posed (as long as this isn\u2019t harmful). It should do this as concisely and efficiently as possible.
Last, AI should answer questions in the same language they are posed, and respond in a helpful tone.

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 form 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.

After creating the application, TruBasicApp allows you to instrument it in one line of code:
In\u00a0[3]: Copied!from trulens_eval import TruBasicApp\nbasic_app_recorder = TruBasicApp(custom_application, app_id=\"Custom Application v1\")\nfrom trulens_eval import TruBasicApp basic_app_recorder = TruBasicApp(custom_application, app_id=\"Custom Application v1\")
Then, you can operate the application like normal:
In\u00a0[4]: Copied!with basic_app_recorder as recording:\n basic_app_recorder.app(\"What is the phone number for HR?\")\nwith basic_app_recorder as recording: basic_app_recorder.app(\"What is the phone number for HR?\")
Read more about TruBasicApp in the API reference or check out the text2text quickstart.
If instead, you're looking to use TruLens with a more complex custom application, you can use TruCustom.
For more information, plese read more about TruCustom in the API Reference
For frameworks with deep integrations, TruLens can expose additional internals of the application for tracking. See TruChain and TruLlama for more details.

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:
@instrument decorator\u00b6","text":"from trulens_eval.tru_custom_app import instrument\n\nclass RAG_from_scratch:\n @instrument\n def retrieve(self, query: str) -> list:\n \"\"\"\n Retrieve relevant text from vector store.\n \"\"\"\n\n @instrument\n def generate_completion(self, query: str, context_str: list) -> str:\n \"\"\"\n Generate answer from context.\n \"\"\"\n\n @instrument\n def query(self, query: str) -> str:\n \"\"\"\n Retrieve relevant text given a query, and then generate an answer from the context.\n \"\"\"\n
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:
instrument.method\u00b6","text":"from trulens_eval.tru_custom_app import instrument\nfrom somepackage.from custom_retriever import CustomRetriever\n\ninstrument.method(CustomRetriever, \"retrieve_chunks\")\n\n# ... rest of the custom class follows ...\n

Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LangChain applications where the BaseRetriever is used, select_context can be used to access the retrieved text for evaluation.
Example usage:
context = TruChain.select_context(rag_chain)\n\nf_context_relevance = (\n Feedback(provider.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(np.mean)\n )\n
For added flexibility, the select_context method is also made available through trulens_eval.app.App. This allows you to switch between frameworks without changing your context selector:
from trulens_eval.app import App\ncontext = App.select_context(rag_chain)\n

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 Llama-Index applications where the source nodes are used, select_context can be used to access the retrieved text for evaluation.
Example usage:
context = TruLlama.select_context(query_engine)\n\nf_context_relevance = (\n Feedback(provider.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(np.mean)\n )\n
For added flexibility, the select_context method is also made available through trulens_eval.app.App. This allows you to switch between frameworks without changing your context selector:
from trulens_eval.app import App\ncontext = App.select_context(query_engine)\n

To instrument an LLM chain, all that's required is to wrap it using TruChain.

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.
Example usage:
context = TruRails.select_context(rails)\n\nf_context_relevance = (\n Feedback(provider.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(np.mean)\n )\n
For added flexibility, the select_context method is also made available through trulens_eval.app.App. This allows you to switch between frameworks without changing your context selector:
from trulens_eval.app import App\ncontext = App.select_context(rag_chain)\nIn\u00a0[7]: Copied!

TruLens provides TruRails, an integration with NeMo Guardrails apps to allow you to inspect and evaluate the internals of your application built using nemo. This is done through the instrumentation of key nemo 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.

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_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)).

"},{"location":"trulens_explain/attribution_parameterization/#advanced-definitions","title":"Advanced Definitions","text":"What is a Distribution of Interest (DoI)?
The distribution of interest is a concept of aggregating attributions over a sample or distribution.
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.
TruLens-Explain is a cross-framework library for deep learning explainability. It provides a uniform abstraction over a number of different frameworks. It provides a uniform abstraction layer over TensorFlow, Pytorch, and Keras and allows input and internal explanations.

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.

rebatch_size int (optional) Will rebatch instances to this size if given. This may be required for GPU usage if using a DoI which produces multiple instances per user-provided instance. Many valued DoIs will expand the tensors sent to each layer to original_batch_size * doi_size. The rebatch size will break up original_batch_size * doi_size into rebatch_size chunks to send to model.

attributions(*model_args: ArgsLike, **model_kwargs: KwargsLike) -> Union[TensorLike, ArgsLike[TensorLike], ArgsLike[ArgsLike[TensorLike]]]\nReturns 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.
PARAMETER DESCRIPTIONmodel_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.

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.

The TruLens library is designed to support models implemented via a variety of different popular python neural network frameworks: Keras (with TensorFlow or Theano backend), TensorFlow, and Pytorch. Models developed with different frameworks implement things (e.g., gradient computations) a number of different ways. We define framework specific ModelWrapper instances to create a unified model API, providing the same functionality to models that are implemented in disparate frameworks. In order to compute attributions for a model, we provide a trulens.nn.models.get_model_wrapper function that will return an appropriate ModelWrapper instance.
Some parameters are exclusively utilized for specific frameworks and are outlined in the parameter descriptions.

One clear use case for measuring attributions is for human consumption. In order to be fully leveraged by humans, explanations need to be interpretable \u2014 a large vector of numbers doesn\u2019t in general make us more confident we understand what a network is doing. We therefore view an explanation as comprised of both an attribution measurement and an interpretation of what the attribution values represent.
One obvious way to interpret attributions, particularly in the image domain, is via visualization. This module provides several visualization methods for interpreting attributions as images.

numpy.ndarrayThe original image(s) over which the attributions are calculated. Must be the same shape as expected by the model used with this visualizer.
numpy.ndarray, optionalIf the model requires a preprocessed input (e.g., with the mean subtracted) that is different from how the image should be visualized, x_preprocessed should be specified. In this case x will be used for visualization, and x_preprocessed will be passed to the model when calculating attributions. Must be the same shape as x.
If specified, the resulting visualization will be saved to a file with the name given by output_file.
If specified, 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.
floatValue in the range [0, 1]. Attribution values at or below the percentile given by threshold will be masked. If None, defaults to the value supplied to the constructor. Default None.
Value in the range [0, 1] specifying the opacity for the parts of the image that are masked. Default 0.2. If None, defaults to the value supplied to the constructor. Default None.

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.

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:
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:

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.
The instrumented versions of functions/methods record the inputs/outputs and some additional data (see 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.
The arguments to a call and its return are converted to json using the same tools as App Data (see above).
"},{"location":"trulens_eval/api/instruments/#trulens_eval.instruments--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).
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:
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. 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.
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.
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:
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.
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.

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?

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.
Try to have all internals be async but for users we may expose sync versions via the sync method. If internals are async and don't need exposure, don't need to provide a synced version.

In notes below, \"HACK###\" can be used to find places in the code where the hack lives.

We inspect the call stack in process of tracking method invocation. It may be possible to replace this with contextvars.
\"HACK012\" -- In the optional imports scheme, we have to make sure that imports that happen from outside of trulens raise exceptions instead of producing dummies without raising exceptions.
See instruments.py docstring for discussion why these are done.
We override and wrap methods from other libraries to track their invocation or API use. Overriding for tracking invocation is done in the base instruments.py:Instrument class while for tracking costs are in the base Endpoint class.
\"HACK009\" -- Cannot reliably determine whether a function referred to by an object that implements __call__ has been instrumented. Hacks to avoid warnings about lack of instrumentation.
See instruments.py docstring for discussion why these are done.
\"HACK002\" -- We override ThreadPoolExecutor in concurrent.futures.
\"HACK007\" -- We override Thread in threading.
trace_method decorator in llama_index does not preserve function signatures; we hack it so that it does.~~ Fixed as of llama_index 0.9.26 or near there.langchain_core.runnables.config.ContextThreadPoolExecutor so it uses our thread starter.\"HACK006\" -- endpoint needs to be added as a keyword arg with default value in some __init__ because pydantic overrides signature without default value otherwise.
\"HACK005\" -- model_validate inside WithClassInfo is implemented in decorated method because pydantic doesn't call it otherwise. It is uncertain whether this is a pydantic bug.
We dump attributes marked to be excluded by pydantic except our own classes. This is because some objects are of interest despite being marked to exclude. Example: RetrievalQA.retriever in langchain.
\"HACK004\" -- Outdated, need investigation whether it can be removed.
~~async/sync code duplication -- Many of our methods are almost identical duplicates due to supporting both async and synced versions. Having trouble with a working approach to de-duplicated the identical code.~~ Fixed. See utils/asynchro.py.
~~\"HACK008\" -- async generator -- Some special handling is used for tracking costs when async generators are involved. See feedback/provider/endpoint/base.py.~~ Fixed in endpoint code.
\"HACK010\" -- cannot tell whether something is a coroutine and need additional checks in sync/desync.
\"HACK011\" -- older pythons don't allow use of Future as a type constructor in annotations. We define a dummy type Future in older versions of python to circumvent this but have to selectively import it to make sure type checking and mkdocs is done right.
\"HACK012\" -- same but with Queue.
Similarly, we define NoneType for older python versions.
\"HACK013\" -- when using from __future__ import annotations for more convenient type annotation specification, one may have to call pydantic's BaseModel.model_rebuild after all types references in annotations in that file have been defined for each model class that uses type annotations that reference types defined after its own definition (i.e. \"forward refs\").

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\nReturns:
{'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}\nOptionally, 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\nReturns:
{'Code implementation': [\n 'What are the subcategories of sensory memory?',\n 'What is the capacity of short-term memory according to Miller (1956)?'\n ],\n 'Short term memory limitations': [\n 'What is the duration of sensory memory?',\n 'What are the limitations of short-term memory in terms of context capacity?'\n ],\n 'Planning and task decomposition challenges': [\n 'How long does sensory memory typically last?',\n 'What are the challenges in long-term planning and task decomposition?'\n ]\n}\nIn combination with record metadata logging, this gives you the ability to understand the performance of your application across different prompt categories.

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.

You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a test set.
However unlike traditional machine learning, user feedback or any \"ground truth\" is largely unavailable. Without ground truth on which to compute metrics on our LLM apps, we can turn to feedback functions as a way to compute metrics for LLM apps.
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 measures the performance of your app, on your data, for your users.
Last, feedback functions are flexible. They can be implemented with any model on the back-end. This includes rule-based systems, smaller models tailored to a particular task, or carefully prompted large language models.
"},{"location":"trulens_eval/evaluation/feedback_functions/anatomy/","title":"Anatomy of Feedback Functions","text":"The Feedback class contains the starting point for feedback function specification and evaluation. A typical use-case looks like this:
from trulens_eval import OpenAI\n\nopenai = OpenAI(model_engine=\"gpt-3.5-turbo\")\n\nf_relevance = Feedback(openai.relevance).on_input_output()\nThe components of this specifications are:
Feedback Providers -- The provider is the back-end on which a given feedback function is run.' Multiple underlying models are available through each provider, such as GPT-4 or Llama-2. In many, but not all cases, the feedback implementation is shared across providers (such as with LLM-based evaluations).
Feedback implementations -- openai.relevance is 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 relevance(self, prompt: str, response: str) -> float:\nThat is, relevance is a plain python method that accepts the prompt and response, both strings, and produces a float (assumed to be between 0.0 and 1.0).
Feedback constructor -- The line Feedback(openai.relevance) constructs a Feedback object with a feedback implementation.
Argument specification -- The next line, 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 relevance (prompt and response) 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:
"},{"location":"trulens_eval/evaluation/feedback_functions/guide/#llama_index-specific-selectors","title":"llama_index-specific selectors","text":"TruLlama.select_source_nodes() -- outputs the selector of the source documents part of the engine output.For more advanced control on the feedback function operation, we allow data selection and aggregation. Consider this feedback example:
f_qs_relevance = Feedback(openai.qs_relevance)\n .on_input()\n .on(Select.Record.app.combine_docs_chain._call.args.inputs.input_documents[:].page_content)\n .aggregate(numpy.min)\n\n# Implementation signature:\n# def qs_relevance(self, question: str, statement: str) -> float:\nArgument Selection specification -- Where we previously set, on_input_output , the on(Select...) line enables specification of where the statement argument to the implementation comes from. The form of the specification will be discussed in further details in the Specifying Arguments section.
Aggregation specification -- The last line aggregate(numpy.min) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type. The input to aggregate must be a method which can be imported globally. This requirement is further elaborated in the next section. This function is called on the float results of feedback function evaluations to produce a single float. The default is numpy.mean.
The result of these lines is that f_qs_relevance can be now be run on app/records and will automatically select the specified components of those apps/records:
record: Record = ...\napp: App = ...\n\nfeedback_result: FeedbackResult = f_qs_relevance.run(app=app, record=record)\nThe object can also be provided to an app wrapper for automatic evaluation:
app: App = tru.Chain(...., feedbacks=[f_qs_relevance])\nThe function or method provided to the Feedback constructor is the implementation of the feedback function which does the actual work of producing a float indicating some quantity of interest.
Note regarding FeedbackMode.DEFERRED -- Any function or method (not static or class methods presently supported) can be provided here but there are additional requirements if your app uses the \"deferred\" feedback evaluation mode (when feedback_mode=FeedbackMode.DEFERRED are specified to app constructor). In those cases the callables must be functions or methods that are importable (see the next section for details). The function/method performing the aggregation has the same requirements.
If using deferred evaluation, the feedback function implementations and aggregation implementations must be functions or methods from a Provider subclass that is importable. That is, the callables must be accessible were you to evaluate this code:
from somepackage.[...] import someproviderclass\nfrom somepackage.[...] import somefunction\n\n# [...] means optionally further package specifications\n\nprovider = someproviderclass(...) # constructor arguments can be included\nfeedback_implementation1 = provider.somemethod\nfeedback_implementation2 = somefunction\nFor provided feedback functions, somepackage is trulens_eval.feedback and someproviderclass is OpenAI or one of the other Provider subclasses. Custom feedback functions likewise need to be importable functions or methods of a provider subclass that can be imported. Critically, functions or classes defined locally in a notebook will not be importable this way.
The mapping between app/records to feedback implementation arguments is specified by the on... methods of the Feedback objects. The general form is:
feedback: Feedback = feedback.on(argname1=selector1, argname2=selector2, ...)\nThat is, Feedback.on(...) returns a new Feedback object with additional argument mappings, the source of argname1 is selector1 and so on for further argument names. The types of selector1 is JSONPath which we elaborate on in the \"Selector Details\".
If argument names are ommitted, they are taken from the feedback function implementation signature in order. That is,
Feedback(...).on(argname1=selector1, argname2=selector2)\nand
Feedback(...).on(selector1, selector2)\nare equivalent assuming the feedback implementation has two arguments, argname1 and argname2, in that order.
Feedback implementations are simple callables that can be run on any arguments matching their signatures. However, once wrapped with Feedback, they are meant to be run on outputs of app evaluation (the \"Records\"). Specifically, Feedback.run has this definition:
def run(self, \n app: Union[AppDefinition, JSON], \n record: Record\n) -> FeedbackResult:\nThat is, the context of a Feedback evaluation is an app (either as AppDefinition or a JSON-like object) and a Record of the execution of the aforementioned app. Both objects are indexable using \"Selectors\". By indexable here we mean that their internal components can be specified by a Selector and subsequently that internal component can be extracted using that selector. Selectors for Feedback start by specifying whether they are indexing into an App or a Record via the __app__ and __record__ special attributes (see Selectors section below).
Apps and Records will be converted to JSON-like structures representing their callstack.
Selectors are of type JSONPath defined in utils/serial.py help specify paths into JSON-like structures (enumerating Record or App contents).
In most cases, the Select object produces only a single item but can also address multiple items.
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()\nIf a selector looks like the below
Select.Record.app.combine_documents_chain._call\nIt can be accessed via the JSON-like via
json_like['app']['combine_documents_chain']['_call']\nThe 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.
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.

tru = ... # your app, extending App\nprint(tru.dict())\nWhen 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.
Feedback functions are implemented in collections in instances of the Provider class. There are three categories of such providers as well as combination providers that make use of one or more of these providers to offer additional feedback functions based capabilities of the constituent providers.

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:
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/evaluation/feedback_selectors/","title":"Feedback Selectors","text":"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()\non_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":"For more advanced control on the feedback function operation, we allow data selection and aggregation. Consider this feedback example:
f_qs_relevance = Feedback(openai.qs_relevance)\n .on_input()\n .on(Select.Record.app.combine_docs_chain._call.args.inputs.input_documents[:].page_content)\n .aggregate(numpy.min)\n\n# Implementation signature:\n# def qs_relevance(self, question: str, statement: str) -> float:\nArgument Selection specification -- Where we previously set, on_input_output , the on(Select...) line enables specification of where the statement argument to the implementation comes from. The form of the specification will be discussed in further details in the Specifying Arguments section.
Aggregation specification -- The last line aggregate(numpy.min) specifies how feedback outputs are to be aggregated. This only applies to cases where the argument specification names more than one value for an input. The second specification, for statement was of this type. The input to aggregate must be a method which can be imported globally. This requirement is further elaborated in the next section. This function is called on the float results of feedback function evaluations to produce a single float. The default is numpy.mean.
The result of these lines is that f_qs_relevance can be now be run on app/records and will automatically select the specified components of those apps/records:
record: Record = ...\napp: App = ...\n\nfeedback_result: FeedbackResult = f_qs_relevance.run(app=app, record=record)\nThe object can also be provided to an app wrapper for automatic evaluation:
app: App = tru.Chain(..., feedbacks=[f_qs_relevance])\nThe function or method provided to the Feedback constructor is the implementation of the feedback function which does the actual work of producing a float indicating some quantity of interest.
Note regarding FeedbackMode.DEFERRED -- Any function or method (not static or class methods presently supported) can be provided here but there are additional requirements if your app uses the \"deferred\" feedback evaluation mode (when feedback_mode=FeedbackMode.DEFERRED are specified to app constructor). In those cases the callables must be functions or methods that are importable (see the next section for details). The function/method performing the aggregation has the same requirements.
If using deferred evaluation, the feedback function implementations and aggregation implementations must be functions or methods from a Provider subclass that is importable. That is, the callables must be accessible were you to evaluate this code:
from somepackage.[...] import someproviderclass\nfrom somepackage.[...] import somefunction\n\n# [...] means optionally further package specifications\n\nprovider = someproviderclass(...) # constructor arguments can be included\nfeedback_implementation1 = provider.somemethod\nfeedback_implementation2 = somefunction\nFor provided feedback functions, somepackage is trulens_eval.feedback and someproviderclass is OpenAI or one of the other Provider subclasses. Custom feedback functions likewise need to be importable functions or methods of a provider subclass that can be imported. Critically, functions or classes defined locally in a notebook will not be importable this way.
The mapping between app/records to feedback implementation arguments is specified by the on... methods of the Feedback objects. The general form is:
feedback: Feedback = feedback.on(argname1=selector1, argname2=selector2, ...)\nThat is, Feedback.on(...) returns a new Feedback object with additional argument mappings, the source of argname1 is selector1 and so on for further argument names. The types of selector1 is JSONPath which we elaborate on in the \"Selector Details\".
If argument names are ommitted, they are taken from the feedback function implementation signature in order. That is,
Feedback(...).on(argname1=selector1, argname2=selector2)\nand
Feedback(...).on(selector1, selector2)\nare equivalent assuming the feedback implementation has two arguments, argname1 and argname2, in that order.
Apps and Records will be converted to JSON-like structures representing their callstack.
Selectors are of type JSONPath defined in utils/serial.py help specify paths into JSON-like structures (enumerating Record or App contents).
In most cases, the Select object produces only a single item but can also address multiple items.
You can access the JSON structure with with_record methods and then calling layout_calls_as_app.
for example
rag_chain.invoke(\"What is Task Decomposition?\")\n\nfrom trulens_eval import TruChain\ntru_recorder = TruChain(\n rag_chain,\n app_id='Chain1_ChatApplication')\n\nresponse, tru_record = tru_recorder.with_record(rag_chain.invoke, \"What is Task Decomposition?\")\njson_like = tru_record.layout_calls_as_app()\nIf a selector looks like the below
Select.Record.app.combine_documents_chain._call\nIt can be accessed via the JSON-like via
json_like['app']['combine_documents_chain']['_call']\nThis structure can also be seen in the TruLens Evaluations UI by clicking on a component of interest in 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.
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.

tru = ... # your app, extending App\nprint(tru.dict())\nWhen 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.

f_lang_match = Feedback(hugs.language_match)\n .on_input_output()\non_input_output is one of many available shortcuts to simplify the selection of components for evaluation.

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:

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>\")\nNote
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)\nIf 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\nWhen 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\"\nNow 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]\nAlternatively, 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()\nTo 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)\nNow 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)\nThen, 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)\nTo finally ingest the record and run feedbacks, we can use add_record.
for record in data:\n virtual_recorder.add_record(rec)\nTo 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)\nThe VirtualApp metadata can also be appended.
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024\nThis 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\"\nThe primary method for evlauating 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:\nOnce 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])\nNow 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?\")\nIn 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 )\nHere 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.These installation instructions assume that you have conda installed and added to your path.

Building and Evaluating a prototype RAG
Reducing Hallucination for RAGs
The AI should not be offensive or discriminatory, either directly or through subtext or bias.
When asked to aid in a dangerous act (e.g. building a bomb), the AI should politely refuse. Ideally the AI will recognize disguised attempts to solicit help for nefarious purposes.
To the best of its abilities, the AI should recognize when it may be providing very sensitive or consequential advice and act with appropriate modesty and care.
What behaviors are considered harmful and to what degree will vary across people and cultures. It will also be context-dependent, i.e. it will depend on the nature of the use.

Harmless Evaluation for LLM apps
Improving Harmlessness for LLM apps
The AI should make a clear attempt to perform the task or answer the question posed (as long as this isn\u2019t harmful). It should do this as concisely and efficiently as possible.
Last, AI should answer questions in the same language they are posed, and respond in a helpful tone.

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 form 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.

After creating the application, TruBasicApp allows you to instrument it in one line of code:
In\u00a0[3]: Copied!from trulens_eval import TruBasicApp\nbasic_app_recorder = TruBasicApp(custom_application, app_id=\"Custom Application v1\")\nfrom trulens_eval import TruBasicApp basic_app_recorder = TruBasicApp(custom_application, app_id=\"Custom Application v1\")
Then, you can operate the application like normal:
In\u00a0[4]: Copied!with basic_app_recorder as recording:\n basic_app_recorder.app(\"What is the phone number for HR?\")\nwith basic_app_recorder as recording: basic_app_recorder.app(\"What is the phone number for HR?\")
Read more about TruBasicApp in the API reference or check out the text2text quickstart.
If instead, you're looking to use TruLens with a more complex custom application, you can use TruCustom.

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:
@instrument decorator\u00b6","text":"from trulens_eval.tru_custom_app import instrument\n\nclass RAG_from_scratch:\n @instrument\n def retrieve(self, query: str) -> list:\n \"\"\"\n Retrieve relevant text from vector store.\n \"\"\"\n\n @instrument\n def generate_completion(self, query: str, context_str: list) -> str:\n \"\"\"\n Generate answer from context.\n \"\"\"\n\n @instrument\n def query(self, query: str) -> str:\n \"\"\"\n Retrieve relevant text given a query, and then generate an answer from the context.\n \"\"\"\n
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:

Doing so allows us to evaluate for metrics including context relevance and groundedness.
For LangChain applications where the BaseRetriever is used, select_context can be used to access the retrieved text for evaluation.
Example usage:
context = TruChain.select_context(rag_chain)\n\nf_context_relevance = (\n Feedback(provider.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(np.mean)\n )\n
For added flexibility, the select_context method is also made available through trulens_eval.app.App. This allows you to switch between frameworks without changing your context selector:
from trulens_eval.app import App\ncontext = App.select_context(rag_chain)\n

TruLens provides TruChain, a deep integration with LangChain to allow you to inspect and evaluate the internals of your application built using LangChain. This is done through the instrumentation of key LangChain classes. To see a list of classes instrumented, see Appendix: Instrumented LangChain Classes and Methods.
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.

To instrument an LLM chain, all that's required is to wrap it using TruChain.
In\u00a0[6]: Copied!from trulens_eval import TruRails\n\n# instrument with TruRails\ntru_recorder = TruRails(\n rails,\n app_id = \"my first trurails app\", # optional\n)\nfrom trulens_eval import TruRails # instrument with TruRails tru_recorder = TruRails( rails, app_id = \"my first trurails app\", # optional )
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.
Example usage:
context = TruRails.select_context(rails)\n\nf_context_relevance = (\n Feedback(provider.qs_relevance)\n .on_input()\n .on(context)\n .aggregate(np.mean)\n )\n
For added flexibility, the select_context method is also made available through trulens_eval.app.App. This allows you to switch between frameworks without changing your context selector:
from trulens_eval.app import App\ncontext = App.select_context(rag_chain)\nIn\u00a0[7]: Copied!

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)).

"},{"location":"trulens_explain/attribution_parameterization/#advanced-definitions","title":"Advanced Definitions","text":"What is a Distribution of Interest (DoI)?
The distribution of interest is a concept of aggregating attributions over a sample or distribution.
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.
TruLens-Explain is a cross-framework library for deep learning explainability. It provides a uniform abstraction over a number of different frameworks. It provides a uniform abstraction layer over TensorFlow, Pytorch, and Keras and allows input and internal explanations.

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.

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.

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.

The TruLens library is designed to support models implemented via a variety of different popular python neural network frameworks: Keras (with TensorFlow or Theano backend), TensorFlow, and Pytorch. Models developed with different frameworks implement things (e.g., gradient computations) a number of different ways. We define framework specific ModelWrapper instances to create a unified model API, providing the same functionality to models that are implemented in disparate frameworks. In order to compute attributions for a model, we provide a trulens.nn.models.get_model_wrapper function that will return an appropriate ModelWrapper instance.
Some parameters are exclusively utilized for specific frameworks and are outlined in the parameter descriptions.
