Overview of this book

RAG-Driven Generative AI provides a roadmap for building effective LLM, computer vision, and generative AI systems that balance performance and costs. This book offers a detailed exploration of RAG and how to design, manage, and control multimodal AI pipelines. By connecting outputs to traceable source documents, RAG improves output accuracy and contextual relevance, offering a dynamic approach to managing large volumes of information. This AI book shows you how to build a RAG framework, providing practical knowledge on vector stores, chunking, indexing, and ranking. You’ll discover techniques to optimize your project’s performance and better understand your data, including using adaptive RAG and human feedback to refine retrieval accuracy, balancing RAG with fine-tuning, implementing dynamic RAG to enhance real-time decision-making, and visualizing complex data with knowledge graphs. You’ll be exposed to a hands-on blend of frameworks like LlamaIndex and Deep Lake, vector databases such as Pinecone and Chroma, and models from Hugging Face and OpenAI. By the end of this book, you will have acquired the skills to implement intelligent solutions, keeping you competitive in fields from production to customer service across any project.

Vector store index query engine

VectorStoreIndex is a type of index within LlamaIndex that implements vector embeddings to represent and retrieve information from documents. These documents with similar meanings will have embeddings that are closer together in the vector space, as we explored in the previous chapter. However, this time, the VectorStoreIndex does not automatically use the existing Deep Lake vector store. It can create a new in-memory vector index, re-embed the documents, and create a new index structure. We will take this approach further in Chapter 4, Multimodal Modular RAG for Drone Technology, when we implement a dataset that contains no indexes or embeddings.

There is no silver bullet to deciding which indexing method is suitable for your project! The best way to make a choice is to test the vector, tree, list, and keyword indexes introduced in this chapter.

We will first create the vector store index:
