The two datasets have a large number of user intents, thus dialog rails. One of them is very generic and has higher-grained intents (chit-chat), while the banking dataset is domain-specific and more fine-grained. More details about running the dialog rails evaluation experiments and the evaluation datasets are available here.</p> <p>Preliminary evaluation results follow next. In all experiments, we have chosen to have a balanced test set with at most 3 samples per intent. For both datasets, we have assessed the performance for various LLMs and also for the number of samples (<code>k = all, 3, 1</code>) per intent that are indexed in the vector database.</p> <p>Take into account that the performance of an LLM is heavily dependent on the prompt, especially due to the more complex prompt used by Guardrails. Therefore, currently, we only release the results for OpenAI models, but more results will follow in the next releases. All results are preliminary, as better prompting can improve them.</p> <p>Important lessons to be learned from the evaluation results:</p> <ul> <li>Each step in the three-step approach (user intent, next step/bot intent, bot message) used by Guardrails offers an improvement in performance.</li> <li>It is important to have at least k=3 samples in the vector database for each user intent (canonical form) to achieve good performance.</li> <li>Some models (e.g., gpt-3.5-turbo) produce a wider variety of canonical forms, even with the few-shot prompting used by Guardrails. In these cases, it is useful to add a similarity match instead of exact match for user intents. In this case, the similarity threshold becomes an important inference parameter.</li> <li>Initial results show that even small models, e.g. dolly-v2-3b, vicuna-7b-v1.3, mpt-7b-instruct, falcon-7b-instruct have good performance for topical rails.</li> <li>Using a single call for topical rails shows similar results to the default method (which uses up to 3 LLM calls for generating the final bot message) in most cases for <code>text-davinci-003</code> model.</li> <li>Initial experiments show that using compact prompts has similar or even better performance on these two datasets compared to using the longer prompts.</li> </ul> <p>Evaluation Date - June 21, 2023.

We hope to bring many developers and enthusiasts together to build better solutions for Trustworthy AI. Our initial release is a starting point. We have built a collection of guardrails and educational examples that provide helpful controls and resist a variety of common attacks, however, they are not perfect. We have conducted adversarial testing on these example bots and will soon release a whitepaper on a larger-scale study. Here are some items to watch out for when creating your own bots:</p> <ol> <li>Over-aggressive moderation: Some of the AI Safety rails, can occasionally block otherwise safe requests. This is more likely to happen when multiple guardrails are used together. One possible strategy to resolve this is to use logic in the flow to reduce unnecessary calls; for example to call fact-checking only for factual questions.</li> <li>Overgeneralization of canonical forms: NeMo Guardrails uses canonical forms like <code>ask about jobs report</code> to guide its behavior and to generalize to situations not explicitly defined in the Colang configuration. It may occasionally get the generalization wrong, so that guardrails miss certain examples or trigger unexpectedly. If this happens, it can often be improved by adding or adjusting the <code>define user</code> forms in the Colang files, or modifying the sample conversations in the configuration.</li> <li>Nondeterminism: LLMs use a concept known as temperature, as well as other techniques, to introduce variation in their responses. This creates a much more natural experience, however, it can on occasion create unexpected behavior in LLM applications that can be difficult to reproduce.

The folder must contain one or more <code>.yml</code> files which contain prompt definitions (inside the <code>prompts</code> key).</p> <p>To override the prompt for a specific model, you need to specify the <code>models</code> key:</p> <pre><code>prompts:\n  - task: general\n    models:\n      - databricks/dolly-v2-3b\n    content: |-\n      ...\n\n  - task: generate_user_intent\n    models:\n      - databricks/dolly-v2-3b\n    content: |-\n      ...\n\n  - ...\n</code></pre> <p>You can associate a prompt for a specific task with multiple LLM models:</p> <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n      - openai/gpt-4\n\n...\n</code></pre> <p>To override the prompt for any other custom purpose, you can specify the <code>mode</code> key. If the corresponding task configuration is run with the same <code>prompting_mode</code>, the custom prompt will be used.</p> <p>As an example of this, let's consider the case of compacting. Some applications might need concise prompts, for instance to avoid handling long contexts, and lower latency at the risk of slightly degraded performance due to the smaller context. For this, you might want to have multiple versions of a prompt for the same task and same model. This can be achieved as follows:</p> <p>Task configuration: <pre><code>models:\n  - type: main\n    engine: openai\n    model: gpt-3.5-turbo\n\nprompting_mode: \"compact\"  # Default value is \"standard\"\n</code></pre></p> <p>Prompts configuration: <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n      - openai/gpt-4\n    content: |-\n      Default prompt tailored for high accuracy with the given models for example by adding the fill {{ history }}\n\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n      - openai/gpt-4\n    content: |-\n      Smaller prompt tailored for high accuracy by reducing number of few shot examples or other means\n    mode: compact\n...\n</code></pre></p> <p>You can have as many different modes as you like for a given task and model, as long as the <code>mode</code> key inside the prompt configuration matches the <code>prompting_mode</code> key in the top-level task configuration, thus enabling an easy setup for prompt engineering experiments.</p> <p>Note that if you specify a custom <code>prompting_mode</code> but no prompt definition with the same custom <code>mode</code> is defined, then, the <code>standard</code> prompt template for that task is used.</p>"},{"location":"trulens_eval/NeMo-Guardrails/docs/user_guides/advanced/prompt-customization/#prompt-templates","title":"Prompt Templates","text":"<p>Depending on the type of LLM, there are two types of templates you can define: completion and chat. For completion models (e.g., <code>gpt-3.5-turbo-instruct</code>), you need to include the <code>content</code> key in the configuration of a prompt:</p> <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo-instruct\n    content: |-\n      ...\n</code></pre> <p>For chat models (e.g., <code>gpt-3.5-turbo</code>), you need to include the <code>messages</code> key in the configuration of a prompt:</p> <p><pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n    messages:\n      - type: system\n        content: ...\n      - type: user\n        content: ...\n      - type: bot\n        content: ...\n      # ...\n</code></pre> For each task, you can also specify the maximum length of the prompt to be used for the LLM call in terms of the number of characters. This is useful if you want to limit the number of tokens used by the LLM or when you want to make sure that the prompt length does not exceed the maximum context length. When the maximum length is exceeded, the prompt is truncated by removing older turns from the conversation history until length of the prompt is less than or equal to the maximum length. The default maximum length is 16000 characters.</p> <p>For example, for the <code>generate_user_intent</code> task, you can specify the following:</p> <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n    max_length: 3000\n</code></pre>"},{"location":"trulens_eval/NeMo-Guardrails/docs/user_guides/advanced/prompt-customization/#content-template","title":"Content Template","text":"<p>The content for a completion prompt or the body for a message in a chat prompt is a string that can also include variables and potentially other types of constructs.

However, it begs the question how trustworthy these scores actually are, given they are at their core next-token-prediction-style generation from meticulously designed prompts. Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI.</p> <p>Another frequent inquiry from the community concerns the intrinsic semantic significance, or lack thereof, of feedback scores\u2014for example, how one would interpret and instrument with a score of 0.9 when assessing context relevance in a RAG application or whether a harmfulness score of 0.7 from GPT-3.5 equates to the same from <code>Llama-2-7b</code>.</p> <p>For simpler meta-evaluation tasks, when human numerical scores are available in the benchmark datasets, such as <code>SummEval</code>, it\u2019s a lot more straightforward to evaluate feedback functions as long as we can define reasonable correlation between the task of the feedback function and the ones available in the benchmarks. Check out our preliminary work on evaluating our own groundedness feedback functions: https://www.trulens.org/trulens_eval/groundedness_smoke_tests/#groundedness-evaluations and our previous blog, where the groundedness metric in the context of RAG can be viewed as equivalent to the consistency metric defined in the SummEval benchmark. In those cases, calculating MAE between our feedback scores and the golden set\u2019s human scores can readily provide insights on how well the groundedness LLM-based feedback functions are aligned with human preferences.</p> <p>Yet, acquiring high-quality, numerically scored datasets is challenging and costly, a sentiment echoed across institutions and companies working on RLFH dataset annotation.</p> <p>Observing that many information retrieval (IR) benchmarks use binary labels,  we propose to frame the problem of evaluating LLM-based feedback functions (meta-evaluation) as evaluating a recommender system. In essence, we argue the relative importance or ranking based on the score assignments is all you need to achieve meta-evaluation against human golden sets. The intuition is that it is a sufficient proxy to trustworthiness if feedback functions demonstrate discriminative capabilities that reliably and consistently assign items, be it context chunks or generated responses, with weights and ordering closely mirroring human preferences.</p> <p>In this following section, we illustrate how we conduct meta-evaluation experiments on one of Trulens most widely used feedback functions: <code>context  relevance</code> and share how well they are aligned with human preferences in practice.</p>"},{"location":"trulens_eval/evaluation/feedback_evaluations/context_relevance_benchmark/#define-feedback-functions-for-contexnt-relevance-to-be-evaluated","title":"Define feedback functions for contexnt relevance to be evaluated\u00b6","text":""},{"location":"trulens_eval/evaluation/feedback_evaluations/context_relevance_benchmark/#visualization","title":"Visualization\u00b6","text":""},{"location":"trulens_eval/evaluation/feedback_evaluations/context_relevance_benchmark_small/","title":"\ud83d\udcd3 Context Relevance Evaluations","text":"In\u00a0[1]: Copied! <pre># Import relevance feedback function\nfrom trulens_eval.feedback import GroundTruthAgreement, OpenAI, LiteLLM\nfrom trulens_eval import TruBasicApp, Feedback, Tru, Select\nfrom test_cases import context_relevance_golden_set\n\nimport openai\n\nTru().reset_database()\n</pre> # Import relevance feedback function from trulens_eval.feedback import GroundTruthAgreement, OpenAI, LiteLLM from trulens_eval import TruBasicApp, Feedback, Tru, Select from test_cases import context_relevance_golden_set  import openai  Tru().reset_database() <pre>\ud83e\udd91 Tru initialized with db url sqlite:///default.sqlite .\n\ud83d\uded1 Secret keys may be written to the database.

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 \ud83e\udd91TruLens-Eval, our scores are real   numbers between 0 and 1.</p> </li> <li> <p><code>Feedback</code>. See <code>Evaluation</code>.</p> </li> <li> <p><code>Feedback Function</code>. A method that implements an <code>Evaluation</code>. This   corresponds to Feedback.</p> </li> <li> <p><code>Generation</code>. See <code>Completion</code>.</p> </li> <li> <p><code>Human Feedback</code>. A feedback that is provided by a human, e.g. a thumbs   up/down in response to a <code>Completion</code>.</p> </li> <li> <p><code>Instruction Prompt</code>, <code>System Prompt</code>. A part of a <code>Prompt</code> given to an <code>LLM</code>   to complete that contains instructions describing the task that the   <code>Completion</code> should solve. Sometimes such prompts include examples of correct   or desirable completions (see <code>Shots</code>). A prompt that does not include examples   is said to be <code>Zero Shot</code>.</p> </li> <li> <p><code>LLM</code>, <code>Large Language Model</code>. The <code>Component</code> of an <code>Application</code> that   performs <code>Completion</code>.</p> </li> <li> <p><code>Memory</code>. The state maintained by an <code>Application</code> or an <code>Agent</code> indicating   anything relevant to continuing, refining, or guiding it towards its   goals. <code>Memory</code> is provided as <code>Context</code> in <code>Prompts</code> and is updated when new   relevant context is processed, be it a user prompt or the results of the   invocation of some <code>Tool</code>. As <code>Memory</code> is included in <code>Prompts</code>, it can be a   natural language description of the state of the app/agent. To limit to size   if memory, <code>Summarization</code> is often used.</p> </li> <li> <p><code>Multi-Agent System</code>. The use of multiple <code>Agents</code> incentivized to interact   with each other to implement some capability. While the term predates <code>LLMs</code>,   the convenience of the common natural language interface makes the approach   much easier to implement.</p> </li> <li> <p><code>Prompt</code>. The text that an <code>LLM</code> completes during <code>Completion</code>. In chat   applications. See also <code>Instruction Prompt</code>, <code>Prompt Template</code>.</p> </li> <li> <p><code>Prompt Template</code>. A piece of text with placeholders to be filled in in order   to build a <code>Prompt</code> for a given task. A <code>Prompt Template</code> will typically   include the <code>Instruction Prompt</code> with placeholders for things like <code>Context</code>,   <code>Memory</code>, or <code>Application</code> configuration parameters.</p> </li> <li> <p><code>Provider</code>. A system that provides the ability to execute models, either   <code>LLM</code>s or classification models. In \ud83e\udd91TruLens-Eval, <code>Feedback Functions</code>   make use of <code>Providers</code> to invoke models for <code>Evaluation</code>.</p> </li> <li> <p><code>RAG</code>, <code>Retrieval Augmented Generation</code>. A common organization of   <code>Applications</code> that combine a <code>Retrieval</code> with an <code>LLM</code> to produce   <code>Completions</code> that incorporate information that an <code>LLM</code> alone may not be   aware of.</p> </li> <li> <p><code>RAG Triad</code> (\ud83e\udd91TruLens-Eval-specific concept). A combination of three   <code>Feedback Functions</code> meant to <code>Evaluate</code> <code>Retrieval</code> steps in <code>Applications</code>.</p> </li> <li> <p><code>Record</code>. A \"record\" of the execution of a single execution of an app. Single   execution means invocation of some top-level app method. Corresponds to   Record</p> <p>Note</p> <p>This will be renamed to <code>Trace</code> in the future.</p> </li> <li> <p><code>Retrieval</code>, <code>Retriever</code>. The process or result (or the <code>Component</code> that   performs this) of looking up pieces of text relevant to a <code>Prompt</code> to provide   as <code>Context</code> to an <code>LLM</code>. Typically this is done using an <code>Embedding</code>   representations.</p> </li> <li> <p><code>Selector</code> (\ud83e\udd91TruLens-Eval-specific concept). A specification of the source   of data from a <code>Trace</code> to use as inputs to a <code>Feedback Function</code>. This   corresponds to Lens and utilities   Select.</p> </li> <li> <p><code>Shot</code>, <code>Zero Shot</code>, <code>Few Shot</code>, <code>&lt;Quantity&gt;-Shot</code>. The use of zero or more   examples in an <code>Instruction Prompt</code> to help an <code>LLM</code> generate desirable   <code>Completions</code>. <code>Zero Shot</code> describes prompts that do not have any examples and   only offer a natural language description of the task, while <code>&lt;Quantity&gt;-Shot</code>   indicate some <code>&lt;Quantity&gt;</code> of examples are provided.</p> </li> <li> <p><code>Span</code>. Some unit of work logged as part of a record. Corresponds to current   \ud83e\udd91RecordAppCallMethod.</p> </li> <li> <p><code>Summarization</code>. The task of condensing some natural language text into a   smaller bit of natural language text that preserves the most important parts   of the text. This can be targetted towards humans or otherwise. It can also be   used to maintain consize <code>Memory</code> in an <code>LLM</code> <code>Application</code> or <code>Agent</code>.   Summarization can be performed by an <code>LLM</code> using a specific <code>Instruction Prompt</code>.</p> </li> <li> <p><code>Tool</code>. A piece of functionality that can be invoked by an <code>Application</code> or   <code>Agent</code>. This commonly includes interfaces to services such as search (generic   search via google or more specific like IMDB for movies). Tools may also   perform actions such as submitting comments to github issues. A <code>Tool</code> may   also encapsulate an interface to an <code>Agent</code> for use as a component in a larger   <code>Application</code>.</p> </li> <li> <p><code>Trace</code>. See <code>Record</code>.</p> </li> </ul>"},{"location":"trulens_eval/getting_started/core_concepts/1_rag_prototype/","title":"Iterating on LLM Apps with TruLens","text":"In\u00a0[\u00a0]: Copied! <pre>!pip install trulens_eval llama_index llama-index-llms-openai llama_hub llmsherpa\n</pre> !pip install trulens_eval llama_index llama-index-llms-openai llama_hub llmsherpa In\u00a0[\u00a0]: Copied! <pre># Set your API keys.

A tensor is a multidimensional object that can be model inputs, or layer activations.</p> <p>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.</p> <p>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. </p> <p>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.</p> <p>What is a Quantity of Interest (QoI)? A QoI is a scalar number that is being explained. </p> <p>E.g. With saliency maps, you get <code>dx/dy</code> (i.e. the effect of input on output). <code>y</code> in this case is the QoI scalar. It is usually the output of a neuron, but could be a sum of multiple neurons.</p> <p>What is an attribution? An attribution is a numerical value associated with every element in a tensor that explains a QoI. </p> <p>E.g. With saliency maps, you get <code>dx/dy</code>. <code>x</code> is the associated tensor. The entirety of <code>dx/dy</code> is the explanation.</p> <p>What are cuts?

The two datasets have a large number of user intents, thus dialog rails. One of them is very generic and has higher-grained intents (chit-chat), while the banking dataset is domain-specific and more fine-grained. More details about running the dialog rails evaluation experiments and the evaluation datasets are available here.</p> <p>Preliminary evaluation results follow next. In all experiments, we have chosen to have a balanced test set with at most 3 samples per intent. For both datasets, we have assessed the performance for various LLMs and also for the number of samples (<code>k = all, 3, 1</code>) per intent that are indexed in the vector database.</p> <p>Take into account that the performance of an LLM is heavily dependent on the prompt, especially due to the more complex prompt used by Guardrails. Therefore, currently, we only release the results for OpenAI models, but more results will follow in the next releases. All results are preliminary, as better prompting can improve them.</p> <p>Important lessons to be learned from the evaluation results:</p> <ul> <li>Each step in the three-step approach (user intent, next step/bot intent, bot message) used by Guardrails offers an improvement in performance.</li> <li>It is important to have at least k=3 samples in the vector database for each user intent (canonical form) to achieve good performance.</li> <li>Some models (e.g., gpt-3.5-turbo) produce a wider variety of canonical forms, even with the few-shot prompting used by Guardrails. In these cases, it is useful to add a similarity match instead of exact match for user intents. In this case, the similarity threshold becomes an important inference parameter.</li> <li>Initial results show that even small models, e.g. dolly-v2-3b, vicuna-7b-v1.3, mpt-7b-instruct, falcon-7b-instruct have good performance for topical rails.</li> <li>Using a single call for topical rails shows similar results to the default method (which uses up to 3 LLM calls for generating the final bot message) in most cases for <code>text-davinci-003</code> model.</li> <li>Initial experiments show that using compact prompts has similar or even better performance on these two datasets compared to using the longer prompts.</li> </ul> <p>Evaluation Date - June 21, 2023.

We hope to bring many developers and enthusiasts together to build better solutions for Trustworthy AI. Our initial release is a starting point. We have built a collection of guardrails and educational examples that provide helpful controls and resist a variety of common attacks, however, they are not perfect. We have conducted adversarial testing on these example bots and will soon release a whitepaper on a larger-scale study. Here are some items to watch out for when creating your own bots:</p> <ol> <li>Over-aggressive moderation: Some of the AI Safety rails, can occasionally block otherwise safe requests. This is more likely to happen when multiple guardrails are used together. One possible strategy to resolve this is to use logic in the flow to reduce unnecessary calls; for example to call fact-checking only for factual questions.</li> <li>Overgeneralization of canonical forms: NeMo Guardrails uses canonical forms like <code>ask about jobs report</code> to guide its behavior and to generalize to situations not explicitly defined in the Colang configuration. It may occasionally get the generalization wrong, so that guardrails miss certain examples or trigger unexpectedly. If this happens, it can often be improved by adding or adjusting the <code>define user</code> forms in the Colang files, or modifying the sample conversations in the configuration.</li> <li>Nondeterminism: LLMs use a concept known as temperature, as well as other techniques, to introduce variation in their responses. This creates a much more natural experience, however, it can on occasion create unexpected behavior in LLM applications that can be difficult to reproduce.

They are located in the nemoguardrails/llm/prompts folder. You can customize the prompts further by including a <code>prompts.yml</code> file in a guardrails configuration (technically, the file name is not essential, and you can also include the <code>prompts</code> key in the general <code>config.yml</code> file).</p> <p>Additionally, if the environment variable <code>PROMPTS_DIR</code> is set, the toolkit will also load any prompts defined in the specified directory. The loading is performed once, when the python module is loaded. The folder must contain one or more <code>.yml</code> files which contain prompt definitions (inside the <code>prompts</code> key).</p> <p>To override the prompt for a specific model, you need to specify the <code>models</code> key:</p> <pre><code>prompts:\n  - task: general\n    models:\n      - databricks/dolly-v2-3b\n    content: |-\n      ...\n\n  - task: generate_user_intent\n    models:\n      - databricks/dolly-v2-3b\n    content: |-\n      ...\n\n  - ...\n</code></pre> <p>You can associate a prompt for a specific task with multiple LLM models:</p> <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n      - openai/gpt-4\n\n...\n</code></pre> <p>To override the prompt for any other custom purpose, you can specify the <code>mode</code> key. If the corresponding task configuration is run with the same <code>prompting_mode</code>, the custom prompt will be used.</p> <p>As an example of this, let's consider the case of compacting. Some applications might need concise prompts, for instance to avoid handling long contexts, and lower latency at the risk of slightly degraded performance due to the smaller context. For this, you might want to have multiple versions of a prompt for the same task and same model. This can be achieved as follows:</p> <p>Task configuration: <pre><code>models:\n  - type: main\n    engine: openai\n    model: gpt-3.5-turbo\n\nprompting_mode: \"compact\"  # Default value is \"standard\"\n</code></pre></p> <p>Prompts configuration: <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n      - openai/gpt-4\n    content: |-\n      Default prompt tailored for high accuracy with the given models for example by adding the fill {{ history }}\n\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n      - openai/gpt-4\n    content: |-\n      Smaller prompt tailored for high accuracy by reducing number of few shot examples or other means\n    mode: compact\n...\n</code></pre></p> <p>You can have as many different modes as you like for a given task and model, as long as the <code>mode</code> key inside the prompt configuration matches the <code>prompting_mode</code> key in the top-level task configuration, thus enabling an easy setup for prompt engineering experiments.</p> <p>Note that if you specify a custom <code>prompting_mode</code> but no prompt definition with the same custom <code>mode</code> is defined, then, the <code>standard</code> prompt template for that task is used.</p>"},{"location":"trulens_eval/NeMo-Guardrails/docs/user_guides/advanced/prompt-customization/#prompt-templates","title":"Prompt Templates","text":"<p>Depending on the type of LLM, there are two types of templates you can define: completion and chat. For completion models (e.g., <code>gpt-3.5-turbo-instruct</code>), you need to include the <code>content</code> key in the configuration of a prompt:</p> <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo-instruct\n    content: |-\n      ...\n</code></pre> <p>For chat models (e.g., <code>gpt-3.5-turbo</code>), you need to include the <code>messages</code> key in the configuration of a prompt:</p> <p><pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n    messages:\n      - type: system\n        content: ...\n      - type: user\n        content: ...\n      - type: bot\n        content: ...\n      # ...\n</code></pre> For each task, you can also specify the maximum length of the prompt to be used for the LLM call in terms of the number of characters. This is useful if you want to limit the number of tokens used by the LLM or when you want to make sure that the prompt length does not exceed the maximum context length. When the maximum length is exceeded, the prompt is truncated by removing older turns from the conversation history until length of the prompt is less than or equal to the maximum length. The default maximum length is 16000 characters.</p> <p>For example, for the <code>generate_user_intent</code> task, you can specify the following:</p> <pre><code>prompts:\n  - task: generate_user_intent\n    models:\n      - openai/gpt-3.5-turbo\n    max_length: 3000\n</code></pre>"},{"location":"trulens_eval/NeMo-Guardrails/docs/user_guides/advanced/prompt-customization/#content-template","title":"Content Template","text":"<p>The content for a completion prompt or the body for a message in a chat prompt is a string that can also include variables and potentially other types of constructs.

Consequently, these feedback functions face typical large language model (LLM) challenges in rigorous production environments, including prompt sensitivity and non-determinism, especially when incorporating Mixture-of-Experts and model-as-a-service solutions like those from OpenAI.</p> <p>Another frequent inquiry from the community concerns the intrinsic semantic significance, or lack thereof, of feedback scores\u2014for example, how one would interpret and instrument with a score of 0.9 when assessing context relevance in a RAG application or whether a harmfulness score of 0.7 from GPT-3.5 equates to the same from <code>Llama-2-7b</code>.</p> <p>For simpler meta-evaluation tasks, when human numerical scores are available in the benchmark datasets, such as <code>SummEval</code>, it\u2019s a lot more straightforward to evaluate feedback functions as long as we can define reasonable correlation between the task of the feedback function and the ones available in the benchmarks. Check out our preliminary work on evaluating our own groundedness feedback functions: https://www.trulens.org/trulens_eval/groundedness_smoke_tests/#groundedness-evaluations and our previous blog, where the groundedness metric in the context of RAG can be viewed as equivalent to the consistency metric defined in the SummEval benchmark. In those cases, calculating MAE between our feedback scores and the golden set\u2019s human scores can readily provide insights on how well the groundedness LLM-based feedback functions are aligned with human preferences.</p> <p>Yet, acquiring high-quality, numerically scored datasets is challenging and costly, a sentiment echoed across institutions and companies working on RLFH dataset annotation.</p> <p>Observing that many information retrieval (IR) benchmarks use binary labels,  we propose to frame the problem of evaluating LLM-based feedback functions (meta-evaluation) as evaluating a recommender system. In essence, we argue the relative importance or ranking based on the score assignments is all you need to achieve meta-evaluation against human golden sets. The intuition is that it is a sufficient proxy to trustworthiness if feedback functions demonstrate discriminative capabilities that reliably and consistently assign items, be it context chunks or generated responses, with weights and ordering closely mirroring human preferences.</p> <p>In this following section, we illustrate how we conduct meta-evaluation experiments on one of Trulens most widely used feedback functions: <code>context  relevance</code> and share how well they are aligned with human preferences in practice.</p>"},{"location":"trulens_eval/evaluation/feedback_evaluations/context_relevance_benchmark/#define-feedback-functions-for-contexnt-relevance-to-be-evaluated","title":"Define feedback functions for contexnt relevance to be evaluated\u00b6","text":""},{"location":"trulens_eval/evaluation/feedback_evaluations/context_relevance_benchmark/#visualization","title":"Visualization\u00b6","text":""},{"location":"trulens_eval/evaluation/feedback_evaluations/context_relevance_benchmark_small/","title":"\ud83d\udcd3 Context Relevance Evaluations","text":"In\u00a0[1]: Copied! <pre># Import relevance feedback function\nfrom trulens_eval.feedback import GroundTruthAgreement, OpenAI, LiteLLM\nfrom trulens_eval import TruBasicApp, Feedback, Tru, Select\nfrom test_cases import context_relevance_golden_set\n\nimport openai\n\nTru().reset_database()\n</pre> # Import relevance feedback function from trulens_eval.feedback import GroundTruthAgreement, OpenAI, LiteLLM from trulens_eval import TruBasicApp, Feedback, Tru, Select from test_cases import context_relevance_golden_set  import openai  Tru().reset_database() <pre>\ud83e\udd91 Tru initialized with db url sqlite:///default.sqlite .\n\ud83d\uded1 Secret keys may be written to the database.

See also <code>Instruction Prompt</code>, <code>Prompt Template</code>.</p> </li> <li> <p><code>Prompt Template</code>. A piece of text with placeholders to be filled in in order   to build a <code>Prompt</code> for a given task. A <code>Prompt Template</code> will typically   include the <code>Instruction Prompt</code> with placeholders for things like <code>Context</code>,   <code>Memory</code>, or <code>Application</code> configuration parameters.</p> </li> <li> <p><code>Provider</code>. A system that provides the ability to execute models, either   <code>LLM</code>s or classification models. In \ud83e\udd91TruLens-Eval, <code>Feedback Functions</code>   make use of <code>Providers</code> to invoke models for <code>Evaluation</code>.</p> </li> <li> <p><code>RAG</code>, <code>Retrieval Augmented Generation</code>. A common organization of   <code>Applications</code> that combine a <code>Retrieval</code> with an <code>LLM</code> to produce   <code>Completions</code> that incorporate information that an <code>LLM</code> alone may not be   aware of.</p> </li> <li> <p><code>RAG Triad</code> (\ud83e\udd91TruLens-Eval-specific concept). A combination of three   <code>Feedback Functions</code> meant to <code>Evaluate</code> <code>Retrieval</code> steps in <code>Applications</code>.</p> </li> <li> <p><code>Record</code>. A \"record\" of the execution of a single execution of an app. Single   execution means invocation of some top-level app method. Corresponds to   Record</p> <p>Note</p> <p>This will be renamed to <code>Trace</code> in the future.</p> </li> <li> <p><code>Retrieval</code>, <code>Retriever</code>. The process or result (or the <code>Component</code> that   performs this) of looking up pieces of text relevant to a <code>Prompt</code> to provide   as <code>Context</code> to an <code>LLM</code>. Typically this is done using an <code>Embedding</code>   representations.</p> </li> <li> <p><code>Selector</code> (\ud83e\udd91TruLens-Eval-specific concept). A specification of the source   of data from a <code>Trace</code> to use as inputs to a <code>Feedback Function</code>. This   corresponds to Lens and utilities   Select.</p> </li> <li> <p><code>Shot</code>, <code>Zero Shot</code>, <code>Few Shot</code>, <code>&lt;Quantity&gt;-Shot</code>. The use of zero or more   examples in an <code>Instruction Prompt</code> to help an <code>LLM</code> generate desirable   <code>Completions</code>. <code>Zero Shot</code> describes prompts that do not have any examples and   only offer a natural language description of the task, while <code>&lt;Quantity&gt;-Shot</code>   indicate some <code>&lt;Quantity&gt;</code> of examples are provided.</p> </li> <li> <p><code>Span</code>. Some unit of work logged as part of a record. Corresponds to current   \ud83e\udd91RecordAppCallMethod.</p> </li> <li> <p><code>Summarization</code>. The task of condensing some natural language text into a   smaller bit of natural language text that preserves the most important parts   of the text. This can be targetted towards humans or otherwise. It can also be   used to maintain consize <code>Memory</code> in an <code>LLM</code> <code>Application</code> or <code>Agent</code>.   Summarization can be performed by an <code>LLM</code> using a specific <code>Instruction Prompt</code>.</p> </li> <li> <p><code>Tool</code>. A piece of functionality that can be invoked by an <code>Application</code> or   <code>Agent</code>. This commonly includes interfaces to services such as search (generic   search via google or more specific like IMDB for movies). Tools may also   perform actions such as submitting comments to github issues. A <code>Tool</code> may   also encapsulate an interface to an <code>Agent</code> for use as a component in a larger   <code>Application</code>.</p> </li> <li> <p><code>Trace</code>. See <code>Record</code>.</p> </li> </ul>"},{"location":"trulens_eval/getting_started/core_concepts/1_rag_prototype/","title":"Iterating on LLM Apps with TruLens","text":"In\u00a0[\u00a0]: Copied! <pre>!pip install trulens_eval llama_index llama-index-llms-openai llama_hub llmsherpa\n</pre> !pip install trulens_eval llama_index llama-index-llms-openai llama_hub llmsherpa In\u00a0[\u00a0]: Copied! <pre># Set your API keys.

A tensor is a multidimensional object that can be model inputs, or layer activations.</p> <p>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.</p> <p>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. </p> <p>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.</p> <p>What is a Quantity of Interest (QoI)? A QoI is a scalar number that is being explained. </p> <p>E.g. With saliency maps, you get <code>dx/dy</code> (i.e. the effect of input on output). <code>y</code> in this case is the QoI scalar. It is usually the output of a neuron, but could be a sum of multiple neurons.</p> <p>What is an attribution? An attribution is a numerical value associated with every element in a tensor that explains a QoI. </p> <p>E.g. With saliency maps, you get <code>dx/dy</code>. <code>x</code> is the associated tensor. The entirety of <code>dx/dy</code> is the explanation.</p> <p>What are cuts?
