Retrieval Augmented Generation (RAG) addresses the limitations of static knowledge in Large Language Models (LLMs) by transforming them into dynamic systems capable of providing accurate, current, and contextually relevant responses. This document outlines a strategic approach for implementing RAG, starting with building a RAG pipeline that integrates a document store, retriever mechanism, and generator to access external knowledge and reduce hallucinations. Selecting the right vector database is crucial for handling high-dimensional data and supporting rapid queries, with options like Pinecone and Milvus highlighted. The choice of embedding models affects retrieval quality, with considerations for domain-specific needs and trade-offs between model size and performance. Hybrid retrieval methods enhance precision and recall by combining dense and sparse techniques, while query transformation techniques improve retrieval relevance by modifying user queries. Post-retrieval processing through reranking and filtering enhances context quality for LLMs, addressing redundancy and ensuring relevance. Continuous evaluation and monitoring are essential for maintaining high-performing RAG systems, with tools like Galileo offering capabilities to optimize and reduce issues over time.
