The document provides an introduction to Retrieval-Augmented Generation (RAG), explaining its definition, importance, and various use cases, including customer support and healthcare. It describes the components of RAG, specifically the roles of the retriever and generator in producing coherent, contextually rich responses. Additionally, it highlights the integration of these components and introduces the LangChain framework for implementation.

Generator: Purpose and Function

8. o
Retriever
- Searches and fetches relevant documents from large
corpus - Uses vector embeddings and semantic search
- Ranks most relevant documents - **Suggested

o
Generator
- Processes retrieved data to generate coherent
response - Uses advanced language models (e.g.,
OpenAI) - Produces human-like text - **Suggested
