The video introduces the concept of RAG fusion, which is a technique used to improve the effectiveness of RAG (Retrieval-Augmented Generation) models. RAG fusion combines multiple search queries generated from a single user input and ranks the results using reciprocal rank fusion. The script also explores the process of implementing RAG fusion using
LangChain and gives examples of how it can be applied in various scenarios.
