Overview of this book

Generative AI is helping organizations tap into their data in new ways, with retrieval-augmented generation (RAG) combining the strengths of large language models (LLMs) with internal data for more intelligent and relevant AI applications. The author harnesses his decade of ML experience in this book to equip you with the strategic insights and technical expertise needed when using RAG to drive transformative outcomes. The book explores RAG’s role in enhancing organizational operations by blending theoretical foundations with practical techniques. You’ll work with detailed coding examples using tools such as LangChain and Chroma’s vector database to gain hands-on experience in integrating RAG into AI systems. The chapters contain real-world case studies and sample applications that highlight RAG’s diverse use cases, from search engines to chatbots. You’ll learn proven methods for managing vector databases, optimizing data retrieval, effective prompt engineering, and quantitatively evaluating performance. The book also takes you through advanced integrations of RAG with cutting-edge AI agents and emerging non-LLM technologies. By the end of this book, you’ll be able to successfully deploy RAG in business settings, address common challenges, and push the boundaries of what’s possible with this revolutionary AI technique.

Indexing

The first stage in the RAG system we will examine more closely is indexing. Note that we are skipping the setup, where we install and import packages, as well as set up OpenAI and related accounts. That is a typical step in every generative artificial intelligence (AI) project, not just RAG systems. We provided a thorough setup guide in Chapter 2, so jump back there if you want to review the libraries we’ve added to support these next steps.

Indexing occurs as the first main stage of RAG. As Figure 4.2 indicates, it is the step after the user query:

In our code from Chapter 2, Indexing is the first section of code you see. This is the step where the data you are introducing to the RAG system is processed. As you can see in the code, the data in this scenario is the web document that is being loaded by WebBaseLoader. This is the beginning of that document (Figure 4.3):
