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.

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.

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? Cuts are tensors that cut a network into two parts. They are composed of a layer and an anchor.</p> <p>What are slices? Slices are two cuts leaving a <code>slice</code> of the network. The attribution will be on the first cut, explaining the QoI on the second cut of the slice.</p> <p>E.g.

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.

As a result it\u2019s a challenge to consistently evaluate parts of an LLM application trace.</p> <p>Therefore, we\u2019ve adapted the use of lenses to refer to parts of an LLM stack trace and use those when defining evaluations. For example, the following lens refers to the input to the retrieve step of the app called query.</p> <pre><code>Select.RecordCalls.retrieve.args.query\n</code></pre> <p>Such lenses can then be used to define evaluations as so:</p> <pre><code># Context relevance between question and each context chunk.\nf_context_relevance = (\n    Feedback(provider.context_relevance_with_cot_reasons, name = \"Context Relevance\")\n    .on(Select.RecordCalls.retrieve.args.query)\n    .on(Select.RecordCalls.retrieve.rets)\n    .aggregate(np.mean)\n)\n</code></pre> <p>In most cases, the Select object produces only a single item but can also address multiple items.</p> <p>For example: <code>Select.RecordCalls.retrieve.args.query</code> refers to only one item.</p> <p>However, <code>Select.RecordCalls.retrieve.rets</code> refers to multiple items.

A <code>Component</code> of an <code>Application</code> or the entirety of an application   that providers a natural language interface to some set of capabilities   typically incorporating <code>Tools</code> to invoke or query local or remote services,   while maintaining its state via <code>Memory</code>. The user of an agent may be a human, a   tool, or another agent. See also <code>Multi Agent System</code>.</p> </li> <li> <p><code>Application</code> or <code>App</code>. An \"application\" that is tracked by \ud83e\udd91TruLens-Eval.   Abstract definition of this tracking corresponds to   App. We offer special support for LangChain via   TruChain, LlamaIndex via   TruLlama, and NeMo Guardrails via   TruRails <code>Applications</code> as well as custom   apps via TruBasicApp or   TruCustomApp, and apps that   already come with <code>Trace</code>s via   TruVirtual.</p> </li> <li> <p><code>Chain</code>.

The use of an <code>Agent</code> to deconstruct its tasks and to   structure, analyze, and refine its <code>Completions</code>.</p> </li> <li> <p><code>Completion</code>, <code>Generation</code>. The process or result of LLM responding to some   <code>Prompt</code>.</p> </li> <li> <p><code>Component</code>. Part of an <code>Application</code> giving it some capability. Typical   components include:</p> </li> <li> <p><code>Retriever</code></p> </li> <li> <p><code>Memory</code></p> </li> <li> <p><code>Tool</code></p> </li> <li> <p><code>Prompt Template</code></p> </li> <li> <p><code>LLM</code></p> </li> <li> <p><code>Embedding</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.

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? Cuts are tensors that cut a network into two parts. They are composed of a layer and an anchor.</p> <p>What are slices? Slices are two cuts leaving a <code>slice</code> of the network. The attribution will be on the first cut, explaining the QoI on the second cut of the slice.</p> <p>E.g.

+<p>Releases are organized in <code>&lt;major&gt;.&lt;minor&gt;.&lt;patch&gt;</code> style. A release is made
+about every week around tuesday-thursday. Releases increment the <code>minor</code> version
+number. Occasionally bug-fix releases occur after a weekly release. Those
+increment only the <code>patch</code> number. No releases have yet made a <code>major</code> version
+increment. Those are expected to be major releases that introduce large number
