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.

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.

-<p>A feedback function scores the output of an LLM application by analyzing generated text as part of an LLM application (or a downstream model or application built on it). This guide provides details about the feedback functions that are implemented out of the box by TruLens. At the end of the guide, you can find additional information about how to create custom feedback functions.</p>

-<p>This evaluates the <em>relevance</em> of the LLM response to the given text by LLM prompting.</p>
-<p>Relevance is currently only available with LLM-based feedback functions.</p>
-<p>TruLens offers two particular flavors of relevance:</p>

-<li>
-<p><em>Prompt response relevance</em> is best for measuring the relationship of the final answer to the user inputed question. This flavor of relevance is particularly optimized for the following features:</p>
+<h1 id="feedback-functions">Feedback Functions<a class="headerlink" href="#feedback-functions" title="Permanent link">&para;</a></h1>
+<p>The <code>Feedback</code> class contains the starting point for feedback function
+specification and evaluation. A typical use-case looks like this:</p>
+<div class="highlight"><pre><span></span><code><span class="kn">from</span> <span class="nn">trulens_eval</span> <span class="kn">import</span> <span class="n">OpenAI</span>

+</code></pre></div>
+<p>The components of this specifications are:</p>
 <ul>
-<li>Relevance requires adherence to the entire prompt.</li>
-<li>Responses that don't provide a definitive answer can still be relevant</li>
-<li>Admitting lack of knowledge and refusals are still relevant.</li>
-<li>Feedback mechanism should differentiate between seeming and actual relevance.</li>
-<li>Relevant but inconclusive statements should get increasingly high scores as they are more helpful for answering the query.</li>
-</ul>
-<p>You can read more information about the performance of prompt response relevance by viewing its <a href="../answer_relevance_smoke_tests/">smoke test results</a>.</p>
+<li>
+<p><strong>Feedback Providers</strong> -- 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).</p>

-<p><em>Question statement relevance</em>, sometimes known as context relevance, is best for measuring the relationship of a provided context to the user inputed question. This flavor of relevance is optimized for a slightly different set of features:</p>
-<ul>
-<li>Relevance requires adherence to the entire query.</li>
-<li>Long context with small relevant chunks are relevant.</li>
-<li>Context that provides no answer can still be relevant.</li>

+<p><strong>Feedback implementations</strong> -- <code>openai.relevance</code> 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:</p>

-<h2 id="groundedness">Groundedness<a class="headerlink" href="#groundedness" title="Permanent link">&para;</a></h2>
-<p>Groundedness uses an LLM or Huggingface NLI to attempt to check if an answer is grounded in its supplied contexts on a scale from 1 to 10. The information overlap or entailment between source and response is then measured, choosing the highest score between sources and then averaged and scaled from 0 to 1.</p>

-<h2 id="language-match">Language Match<a class="headerlink" href="#language-match" title="Permanent link">&para;</a></h2>
-<p>This evaluates if the language of the prompt and response match.</p>
-<p>Language match is currently only available to use with HuggingFace as the model provider. This feedback function returns a score in the range from 0 to 1, where 1 indicates match and 0 indicates mismatch.</p>

-<p>This evaluates the toxicity of the prompt or response.</p>
-<p>Toxicity is currently only available to be used with HuggingFace, and uses a classification endpoint to return a score from 0 to 1. The feedback function is negated as not_toxicity, and returns a 1 if not toxic and a 0 if toxic.</p>
-<h2 id="moderation">Moderation<a class="headerlink" href="#moderation" title="Permanent link">&para;</a></h2>
-<p>The OpenAI Moderation API is made available for use as feedback functions. This includes hate, hate/threatening, self-harm, sexual, sexual/minors, violence, and violence/graphic. Each is negated (ex: not_hate) so that a 0 would indicate that the moderation rule is violated. These feedback functions return a score in the range 0 to 1.</p>
-<h2 id="stereotypes">Stereotypes<a class="headerlink" href="#stereotypes" title="Permanent link">&para;</a></h2>
-<p>This evaluates stereotypes using an LLM to check if gender or race were assumed with no prior indication. This is rated on a scale from 1 to 10 where 10 being no new gender or race assumptions. A two indicates gender or race assumption with no indication, and a one indicates gender or race changes with prior indication that is different.</p>
-<h2 id="summarization">Summarization<a class="headerlink" href="#summarization" title="Permanent link">&para;</a></h2>
-<p>This evaluates summarization tasks using an LLM to check how well a summarization hits upon main points. This is rated on a scale from 1 to 10 where 10 being all points are addressed. </p>
-<h2 id="embeddings-distance">Embeddings Distance<a class="headerlink" href="#embeddings-distance" title="Permanent link">&para;</a></h2>
-<p>Given an embedder, as is typical in vector DBs, this evaluates the distance of the query and document embeddings. Currently supporting cosine distance, L1/Manhattan distance, and L2/Euclidean distance.</p>

+  <h1>What is a Feedback Function?</h1>
+
+<p>Measuring the performance of LLM apps is a critical step in the path from development to production. You would not move a traditional ML system to production without first gaining confidence by measuring its accuracy on a test set.</p>
+<p>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.</p>
+<p>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 <strong>your app, on your data, for your users</strong>.</p>
+<p>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.</p>

+
+<p>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 <code>recorder</code>.</p>
+<p>At the most basic level, feedback implementations are simple callables that can be run on any arguments
+matching their signatures like so:</p>
+<div class="highlight"><pre><span></span><code><span class="n">feedback_result</span> <span class="o">=</span> <span class="n">provider</span><span class="o">.</span><span class="n">relevance</span><span class="p">(</span><span class="s2">&quot;&lt;some prompt&gt;&quot;</span><span class="p">,</span> <span class="s2">&quot;&lt;some response&gt;&quot;</span><span class="p">)</span>

+<p>If your application was run (and logged) outside of TruLens, <code>TruVirtual</code> can be used to ingest and evluate the logs.</p>
+<p>To incorporate your data into TruLens, you have two options. You can either create a <code>Record</code> directly, or you can use the <code>VirtualRecord</code> class, which is designed to help you build records so they can be ingested to TruLens.</p>
+<p>The parameters you'll use with <code>VirtualRecord</code> are the same as those for <code>Record</code>, with one key difference: calls are specified using selectors.</p>
+<p>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.</p>

+  <h1>Running with your app</h1>
+
+<p>The primary method for evlauating LLM apps is by running feedback functions with your app.</p>
+<p>To do so, you first need to define the wrap the specified feedback implementation with <code>Feedback</code> and select what components of your app to evaluate. Optionally, you can also select an aggregation method.</p>
+<div class="highlight"><pre><span></span><code><span class="n">f_context_relevance</span> <span class="o">=</span> <span class="n">Feedback</span><span class="p">(</span><span class="n">openai</span><span class="o">.</span><span class="n">qs_relevance</span><span class="p">)</span>
+    <span class="o">.</span><span class="n">on_input</span><span class="p">()</span>
+    <span class="o">.</span><span class="n">on</span><span class="p">(</span><span class="n">context</span><span class="p">)</span>
+    <span class="o">.</span><span class="n">aggregate</span><span class="p">(</span><span class="n">numpy</span><span class="o">.</span><span class="n">min</span><span class="p">)</span>
+
+<span class="c1"># Implementation signature:</span>
+<span class="c1"># def qs_relevance(self, question: str, statement: str) -&gt; float:</span>
+</code></pre></div>
+<p>Once you've defined the feedback functions to run with your application, you can then pass them as a list to the instrumentation class of your choice, along with the app itself. These make up the <code>recorder</code>.</p>
+<div class="highlight"><pre><span></span><code><span class="kn">from</span> <span class="nn">trulens_eval</span> <span class="kn">import</span> <span class="n">TruChain</span>
+<span class="c1"># f_lang_match, f_qa_relevance, f_context_relevance are feedback functions</span>
+<span class="n">tru_recorder</span> <span class="o">=</span> <span class="n">TruChain</span><span class="p">(</span>
+    <span class="n">chain</span><span class="p">,</span>
+    <span class="n">app_id</span><span class="o">=</span><span class="s1">&#39;Chain1_ChatApplication&#39;</span><span class="p">,</span>
+    <span class="n">feedbacks</span><span class="o">=</span><span class="p">[</span><span class="n">f_lang_match</span><span class="p">,</span> <span class="n">f_qa_relevance</span><span class="p">,</span> <span class="n">f_context_relevance</span><span class="p">])</span>
+</code></pre></div>
+<p>Now that you've included the evaluations as a component of your <code>recorder</code>, 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: <code>with_app_thread</code>.</p>
+<div class="highlight"><pre><span></span><code><span class="k">with</span> <span class="n">tru_recorder</span> <span class="k">as</span> <span class="n">recording</span><span class="p">:</span>
+    <span class="n">chain</span><span class="p">(</span><span class="s2">&quot;&quot;</span><span class="n">What</span> <span class="ow">is</span> <span class="n">langchain</span><span class="err">?</span><span class="s2">&quot;)</span>
+</code></pre></div>
+<p>In addition to <code>with_app_thread</code>, 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:</p>
+<div class="highlight"><pre><span></span><code><span class="kn">from</span> <span class="nn">trulens_eval</span> <span class="kn">import</span> <span class="n">FeedbackMode</span>
+
+<span class="n">tru_recorder</span> <span class="o">=</span> <span class="n">TruChain</span><span class="p">(</span>
+    <span class="n">chain</span><span class="p">,</span>
+    <span class="n">app_id</span><span class="o">=</span><span class="s1">&#39;Chain1_ChatApplication&#39;</span><span class="p">,</span>
+    <span class="n">feedbacks</span><span class="o">=</span><span class="p">[</span><span class="n">f_lang_match</span><span class="p">,</span> <span class="n">f_qa_relevance</span><span class="p">,</span> <span class="n">f_context_relevance</span><span class="p">],</span>
+    <span class="n">feedback_mode</span><span class="o">=</span><span class="n">FeedbackMode</span><span class="o">.</span><span class="n">DEFERRED</span>
+    <span class="p">)</span>
+</code></pre></div>
+<p>Here are the different feedback modes you can use:</p>

+  <h1>Overview</h1>
+
+<p>Feedback selection is the process of determining which components of your application to evaluate.</p>
+<p>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.</p>
+<p>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.</p>
+<p>As a reminder, a typical feedback definition looks like this:</p>
+<div class="highlight"><pre><span></span><code><span class="n">f_lang_match</span> <span class="o">=</span> <span class="n">Feedback</span><span class="p">(</span><span class="n">hugs</span><span class="o">.</span><span class="n">language_match</span><span class="p">)</span>
+    <span class="o">.</span><span class="n">on_input_output</span><span class="p">()</span>
+</code></pre></div>
+<p><code>on_input_output</code> is one of many available shortcuts to simplify the selection of components for evaluation. We'll cover that in a later section.</p>
+<p>The selector, <code>on_input_output</code>, specifies how the <code>language_match</code> arguments are to be determined from an app record or app
+definition. The general form of this specification is done using <code>on</code> but
+several shorthands are provided. <code>on_input_output</code> states that the first two
+argument to <code>language_match</code> (<code>text1</code> and <code>text2</code>) are to be the main app
+input and the main output, respectively.</p>
+<p>This flexibility to select and evaluate any component of your application allows the developer to be unconstrained in their creativity. <strong>The evaluation framework should not designate how you can build your app.</strong></p>

+  <h1>Generating Test Cases</h1>
+
+<p>Generating a sufficient test set for evaluating an app is an early change in the development phase.</p>
+<p>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 <code>depth</code>, for <code>breadth</code> categories of prompts. Resulting test set will be made up of <code>breadth</code> X <code>depth</code> prompts organized by prompt category.</p>
+<p>Example:</p>
+<div class="highlight"><pre><span></span><code><span class="kn">from</span> <span class="nn">trulens_eval.generate_test_set</span> <span class="kn">import</span> <span class="n">GenerateTestSet</span>

+<span class="n">test_set</span>
+</code></pre></div>

+</code></pre></div>
+<p>Optionally, you can also provide a list of examples (few-shot) to guide the LLM app to a particular type of question.</p>
+<p>Example:</p>

+  <h1>Selecting Components</h1>
+
+<p>For more advanced control on the feedback function operation, we allow data
+selection and aggregation. Consider this feedback example:</p>
+<div class="highlight"><pre><span></span><code><span class="n">f_qs_relevance</span> <span class="o">=</span> <span class="n">Feedback</span><span class="p">(</span><span class="n">openai</span><span class="o">.</span><span class="n">qs_relevance</span><span class="p">)</span>
+    <span class="o">.</span><span class="n">on_input</span><span class="p">()</span>
+    <span class="o">.</span><span class="n">on</span><span class="p">(</span><span class="n">Select</span><span class="o">.</span><span class="n">Record</span><span class="o">.</span><span class="n">app</span><span class="o">.</span><span class="n">combine_docs_chain</span><span class="o">.</span><span class="n">_call</span><span class="o">.</span><span class="n">args</span><span class="o">.</span><span class="n">inputs</span><span class="o">.</span><span class="n">input_documents</span><span class="p">[:]</span><span class="o">.</span><span class="n">page_content</span><span class="p">)</span>
+    <span class="o">.</span><span class="n">aggregate</span><span class="p">(</span><span class="n">numpy</span><span class="o">.</span><span class="n">min</span><span class="p">)</span>
+
+<span class="c1"># Implementation signature:</span>
+<span class="c1"># def qs_relevance(self, question: str, statement: str) -&gt; float:</span>
+</code></pre></div>
+<ul>
+<li>
+<p><strong>Argument Selection specification</strong> -- Where we previously set,
+  <code>on_input_output</code> , the <code>on(Select...)</code> 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.</p>
+</li>
+<li>
+<p><strong>Aggregation specification</strong> -- The last line <code>aggregate(numpy.min)</code> 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 <code>statement</code> was of this type. The input to <code>aggregate</code> must
+  be a method which can be imported globally. This requirement is further
+  elaborated in the next section. This function is called on the <code>float</code> results
+  of feedback function evaluations to produce a single float. The default is
+  <code>numpy.mean</code>.</p>
+</li>
+</ul>
+<p>The result of these lines is that <code>f_qs_relevance</code> can be now be run on
+app/records and will automatically select the specified components of those
+apps/records:</p>
+<div class="highlight"><pre><span></span><code><span class="n">record</span><span class="p">:</span> <span class="n">Record</span> <span class="o">=</span> <span class="o">...</span>
+<span class="n">app</span><span class="p">:</span> <span class="n">App</span> <span class="o">=</span> <span class="o">...</span>
+
+<span class="n">feedback_result</span><span class="p">:</span> <span class="n">FeedbackResult</span> <span class="o">=</span> <span class="n">f_qs_relevance</span><span class="o">.</span><span class="n">run</span><span class="p">(</span><span class="n">app</span><span class="o">=</span><span class="n">app</span><span class="p">,</span> <span class="n">record</span><span class="o">=</span><span class="n">record</span><span class="p">)</span>
+</code></pre></div>
+<p>The object can also be provided to an app wrapper for automatic evaluation:</p>
+<div class="highlight"><pre><span></span><code><span class="n">app</span><span class="p">:</span> <span class="n">App</span> <span class="o">=</span> <span class="n">tru</span><span class="o">.</span><span class="n">Chain</span><span class="p">(</span><span class="o">...</span><span class="p">,</span> <span class="n">feedbacks</span><span class="o">=</span><span class="p">[</span><span class="n">f_qs_relevance</span><span class="p">])</span>
+</code></pre></div>
+<h2 id="specifying-implementation-function-and-aggregate">Specifying Implementation Function and Aggregate<a class="headerlink" href="#specifying-implementation-function-and-aggregate" title="Permanent link">&para;</a></h2>
+<p>The function or method provided to the <code>Feedback</code> constructor is the
+implementation of the feedback function which does the actual work of producing
+a float indicating some quantity of interest.</p>
+<p><strong>Note regarding FeedbackMode.DEFERRED</strong> -- 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 <code>feedback_mode=FeedbackMode.DEFERRED</code> 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.</p>
+<h3 id="import-requirement-deferred-feedback-mode-only">Import requirement (DEFERRED feedback mode only)<a class="headerlink" href="#import-requirement-deferred-feedback-mode-only" title="Permanent link">&para;</a></h3>
+<p>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:</p>
+<div class="highlight"><pre><span></span><code><span class="kn">from</span> <span class="nn">somepackage.</span><span class="p">[</span><span class="o">...</span><span class="p">]</span> <span class="kn">import</span> <span class="nn">someproviderclass</span>

+<span class="n">feedback_implementation2</span> <span class="o">=</span> <span class="n">somefunction</span>
+</code></pre></div>
+<p>For provided feedback functions, <code>somepackage</code> is <code>trulens_eval.feedback</code> and
+<code>someproviderclass</code> is <code>OpenAI</code> or one of the other <code>Provider</code> 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.</p>
+<h2 id="specifying-arguments">Specifying Arguments<a class="headerlink" href="#specifying-arguments" title="Permanent link">&para;</a></h2>
+<p>The mapping between app/records to feedback implementation arguments is
+specified by the <code>on...</code> methods of the <code>Feedback</code> objects. The general form is:</p>
+<div class="highlight"><pre><span></span><code><span class="n">feedback</span><span class="p">:</span> <span class="n">Feedback</span> <span class="o">=</span> <span class="n">feedback</span><span class="o">.</span><span class="n">on</span><span class="p">(</span><span class="n">argname1</span><span class="o">=</span><span class="n">selector1</span><span class="p">,</span> <span class="n">argname2</span><span class="o">=</span><span class="n">selector2</span><span class="p">,</span> <span class="o">...</span><span class="p">)</span>
+</code></pre></div>
+<p>That is, <code>Feedback.on(...)</code> returns a new <code>Feedback</code> object with additional
+argument mappings, the source of <code>argname1</code> is <code>selector1</code> and so on for further
+argument names. The types of <code>selector1</code> is <code>JSONPath</code> which we elaborate on in
+the "Selector Details".</p>
+<p>If argument names are ommitted, they are taken from the feedback function
+implementation signature in order. That is,</p>
+<div class="highlight"><pre><span></span><code><span class="n">Feedback</span><span class="p">(</span><span class="o">...</span><span class="p">)</span><span class="o">.</span><span class="n">on</span><span class="p">(</span><span class="n">argname1</span><span class="o">=</span><span class="n">selector1</span><span class="p">,</span> <span class="n">argname2</span><span class="o">=</span><span class="n">selector2</span><span class="p">)</span>

+</code></pre></div>
+<p>are equivalent assuming the feedback implementation has two arguments,
+<code>argname1</code> and <code>argname2</code>, in that order.</p>
+<h3 id="selector-details">Selector Details<a class="headerlink" href="#selector-details" title="Permanent link">&para;</a></h3>
+<p>Apps and Records will be converted to JSON-like structures representing their callstack.</p>
+<p>Selectors are of type <code>JSONPath</code> defined in <code>utils/serial.py</code> help specify paths into JSON-like
+structures (enumerating <code>Record</code> or <code>App</code> contents).</p>
+<p>In most cases, the Select object produces only a single item but can also
+address multiple items.</p>
+<p>You can access the JSON structure with <code>with_record</code> methods and then calling <code>layout_calls_as_app</code>.</p>
+<p>for example</p>
+<div class="highlight"><pre><span></span><code>response = my_llm_app(query)
+
+from trulens_eval import TruChain
+tru_recorder = TruChain(
+    my_llm_app,
+    app_id=&#39;Chain1_ChatApplication&#39;)
+
+response, tru_record = tru_recorder.with_record(my_llm_app, query)
+json_like = tru_record.layout_calls_as_app()
+</code></pre></div>
+<p>If a selector looks like the below</p>
+<div class="highlight"><pre><span></span><code>Select.Record.app.combine_documents_chain._call
+</code></pre></div>
+<p>It can be accessed via the JSON-like via</p>
+<div class="highlight"><pre><span></span><code>json_like[&#39;app&#39;][&#39;combine_documents_chain&#39;][&#39;_call&#39;]
+</code></pre></div>
+<p>This structure can also be seen in the TruLens Evaluations UI by clicking on a component of interest in the timeline.</p>
+<p>The top level record also contains these helper accessors</p>
+<ul>
+<li>
+<p><code>RecordInput = Record.main_input</code> -- 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 <code>__call__</code> method).</p>
+</li>
+<li>
+<p><code>RecordOutput = Record.main_output</code> -- points to the main output part of a
+  Record. This is the output of the root method of an app (i.e. <code>__call__</code>
+  for langchain Chains).</p>
+</li>
+<li>
+<p><code>RecordCalls = Record.app</code> -- points to the root of the app-structured
+  mirror of calls in a record. See <strong>App-organized Calls</strong> Section above.</p>
+</li>
+</ul>
+<h2 id="multiple-inputs-per-argument">Multiple Inputs Per Argument<a class="headerlink" href="#multiple-inputs-per-argument" title="Permanent link">&para;</a></h2>
+<p>As in the <code>f_qs_relevance</code> example, a selector for a <em>single</em> 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.</p>
+<p>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.</p>

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

+
+<p>As a reminder, a typical feedback definition looks like this:</p>
+<div class="highlight"><pre><span></span><code><span class="n">f_lang_match</span> <span class="o">=</span> <span class="n">Feedback</span><span class="p">(</span><span class="n">hugs</span><span class="o">.</span><span class="n">language_match</span><span class="p">)</span>
+    <span class="o">.</span><span class="n">on_input_output</span><span class="p">()</span>
+</code></pre></div>
+<p><code>on_input_output</code> is one of many available shortcuts to simplify the selection of components for evaluation.</p>
+<p>The selector, <code>on_input_output</code>, specifies how
+the <code>language_match</code> arguments are to be determined from an app record or app
+definition. The general form of this specification is done using <code>on</code> but
+several shorthands are provided. <code>on_input_output</code> states that the first two
+argument to <code>language_match</code> (<code>text1</code> and <code>text2</code>) are to be the main app
+input and the main output, respectively.</p>
+<p>Several utility methods starting with <code>.on</code> provide shorthands:</p>
+<ul>
+<li>
+<p><code>on_input(arg) == on_prompt(arg: Optional[str])</code> -- both specify that the next
+  unspecified argument or <code>arg</code> should be the main app input.</p>
+</li>
+<li>
+<p><code>on_output(arg) == on_response(arg: Optional[str])</code> -- specify that the next
+  argument or <code>arg</code> should be the main app output.</p>
+</li>
+<li>
+<p><code>on_input_output() == on_input().on_output()</code> -- specifies that the first
+  two arguments of implementation should be the main app input and main app
+  output, respectively.</p>
+</li>
+<li>
+<p><code>on_default()</code> -- depending on signature of implementation uses either
+  <code>on_output()</code> if it has a single argument, or <code>on_input_output</code> if it has
+  two arguments.</p>
+</li>
+</ul>
+<p>Some wrappers include additional shorthands:</p>
+<h3 id="llama-index-specific-selectors">Llama-Index specific selectors<a class="headerlink" href="#llama-index-specific-selectors" title="Permanent link">&para;</a></h3>
+<ul>
+<li><code>TruLlama.select_source_nodes()</code> -- outputs the selector of the source
+  documents part of the engine output.</li>
