Systematic evaluation is needed to support reliable, non-hallucinatory LLM-based applications. TruLens contains instrumentation and evaluation tools for large language model (LLM)-based applications. For evaluation, TruLens provides a set of feedback functions, analogous to labeling functions, to programmatically score the input, output and intermediate text of an LLM app. Each LLM application request can be scored on its question-answer relevance, context relevance and groundedness. These feedback functions provide evidence that your LLM-application is non-hallucinatory. In addition to the above, feedback functions also support the evaluation of ground truth agreement, sentiment, model agreement, language match, toxicity, and a full suite of moderation evaluations, including hate, violence and more. TruLens implements feedback functions as an extensible framework that can evaluate your custom needs as well. During the development cycle, TruLens supports the iterative development of a wide range of LLM applications by wrapping your application to log cost, latency, key metadata and evaluations of each application run. This allows you to track and identify failure modes, pinpoint their root cause, and measure improvement across experiments. ### [​](#why-pinecone) Why Pinecone? #################### File: docs-pinecone-io-integrations-trulens-trulens-for-evaluation-and-tracking-of-llm-experiments-44429.txt Page: 1 Context: To build an effective RAG-style LLM application, it is important to experiment with various configuration choices while setting up your Pinecone vector database, and study their impact on performance metrics.

These feedback functions provide evidence that your LLM-application is non-hallucinatory. In addition to the above, feedback functions also support the evaluation of ground truth agreement, sentiment, model agreement, language match, toxicity, and a full suite of moderation evaluations, including hate, violence and more. TruLens implements feedback functions as an extensible framework that can evaluate your custom needs as well. During the development cycle, TruLens supports the iterative development of a wide range of LLM applications by wrapping your application to log cost, latency, key metadata and evaluations of each application run. This allows you to track and identify failure modes, pinpoint their root cause, and measure improvement across experiments. ### [​](#why-pinecone) Why Pinecone? #################### File: docs-pinecone-io-integrations-trulens-build-the-vector-store-44437.txt Page: 1 Context: To build an effective RAG-style LLM application, it is important to experiment with various configuration choices while setting up your Pinecone vector database, and study their impact on performance metrics.

In each component of this application, different configuration choices can be made that can impact downstream performance. Some of these choices include the following: **Constructing the Vector DB** * Data preprocessing and selection * Chunk Size and Chunk Overlap * Index distance metric * Selection of embeddings **Retrieval** * Amount of context retrieved (top k) * Query planning **LLM** * Prompting * Model choice * Model parameters (size, temperature, frequency penalty, model retries, etc.) These configuration choices are useful to keep in mind when constructing your app. In general, there is no optimal choice for all use cases.

In this example, we explore the downstream impact of some of these configuration choices on response quality, cost and latency with a sample LLM application built with Pinecone as the vector DB. The evaluation and experiment tracking is done with the [TruLens](https://www.trulens.org/) open source library. TruLens offers an extensible set of [feedback functions](https://truera.com/ai-quality-education/generative-ai-and-llms/whats-missing-to-evaluate-foundation-models-at-scale/) to evaluate LLM apps and enables developers to easily track their LLM app experiments. In each component of this application, different configuration choices can be made that can impact downstream performance. Some of these choices include the following: **Constructing the Vector DB** * Data preprocessing and selection * Chunk Size and Chunk Overlap * Index distance metric * Selection of embeddings **Retrieval** * Amount of context retrieved (top k) * Query planning **LLM** * Prompting * Model choice * Model parameters (size, temperature, frequency penalty, model retries, etc.) These configuration choices are useful to keep in mind when constructing your app. In general, there is no optimal choice for all use cases. Rather, we recommend that you experiment with and evaluate a variety of configurations to find the optimal selection as you are building your application. #### [​](#creating-the-index-in-pinecone) Creating the index in Pinecone Here we’ll download a pre-embedded dataset from the `pinecone-datasets` library allowing us to skip the embedding and preprocessing steps.

Large language models alone have a hallucination problem. Several decades of machine learning research have optimized models, including modern LLMs, for generalization, while actively penalizing memorization. However, many of today’s applications require factual, grounded answers. LLMs are also expensive to train, and provided by third party APIs. This means the knowledge of an LLM is fixed. Retrieval-augmented generation (RAG) is a way to reliably ensure models are grounded, with Pinecone as the curated source of real world information, long term memory, application domain knowledge, or whitelisted data. In the RAG paradigm, rather than just passing a user question directly to a language model, the system retrieves any documents that could be relevant in answering the question from the knowledge base, and then passes those documents (along with the original question) to the language model to generate the final response. The most popular method for RAG involves chaining together LLMs with vector databases, such as the widely used Pinecone vector DB. In this process, a numerical vector (an embedding) is calculated for all documents, and those vectors are then stored in a database optimized for storing and querying vectors. Incoming queries are vectorized as well, typically using an encoder LLM to convert the query into an embedding. The query embedding is then matched via embedding similarity against the document embeddings in the vector database to retrieve the documents that are relevant to the query. Pinecone makes it easy to build high-performance vector search applications, including retrieval-augmented question answering. Pinecone can easily handle very large scales of hundreds of millions and even billions of vector embeddings. Pinecone’s large scale allows it to handle long term memory or a large corpus of rich external and domain-appropriate data so that the LLM component of RAG application can focus on tasks like summarization, inference and planning. This setup is optimal for developing a non-hallucinatory application. In addition, Pinecone is fully managed, so it is easy to change configurations and components. Combined with the tracking and evaluation with TruLens, this is a powerful combination that enables fast iteration of your application. ### [​](#using-pinecone-and-trulens-to-improve-llm-performance-and-reduce-hallucination) #################### File: docs-pinecone-io-integrations-trulens-why-trulens-44442.txt Page: 1 Context: ### [​](#why-pinecone) Why Pinecone?

Incoming queries are vectorized as well, typically using an encoder LLM to convert the query into an embedding. The query embedding is then matched via embedding similarity against the document embeddings in the vector database to retrieve the documents that are relevant to the query. Pinecone makes it easy to build high-performance vector search applications, including retrieval-augmented question answering. Pinecone can easily handle very large scales of hundreds of millions and even billions of vector embeddings. Pinecone’s large scale allows it to handle long term memory or a large corpus of rich external and domain-appropriate data so that the LLM component of RAG application can focus on tasks like summarization, inference and planning. This setup is optimal for developing a non-hallucinatory application. In addition, Pinecone is fully managed, so it is easy to change configurations and components. Combined with the tracking and evaluation with TruLens, this is a powerful combination that enables fast iteration of your application. ### [​](#using-pinecone-and-trulens-to-improve-llm-performance-and-reduce-hallucination) #################### File: docs-pinecone-io-integrations-trulens-trulens-for-evaluation-and-tracking-of-llm-experiments-44429.txt Page: 1 Context: ### [​](#why-pinecone) Why Pinecone? Large language models alone have a hallucination problem. Several decades of machine learning research have optimized models, including modern LLMs, for generalization, while actively penalizing memorization. However, many of today’s applications require factual, grounded answers. LLMs are also expensive to train, and provided by third party APIs. This means the knowledge of an LLM is fixed. Retrieval-augmented generation (RAG) is a way to reliably ensure models are grounded, with Pinecone as the curated source of real world information, long term memory, application domain knowledge, or whitelisted data. In the RAG paradigm, rather than just passing a user question directly to a language model, the system retrieves any documents that could be relevant in answering the question from the knowledge base, and then passes those documents (along with the original question) to the language model to generate the final response.
