Advanced RAG Q&A Chatbot

• In this project I have built an advanced RAG Q&A chatbot with chain and retrievers using Langchain

Description

• Retrievers: A retriever is an interface that returns documents given an unstructured query. It is more general than a vector store.
• A retriever does not need to be able to store documents, only to return (or retrieve) them. Vector stores can be used as the backbone of a retriever, but there are other types of retrievers as well.
• Retrieval chain:This chain takes in a user inquiry, which is then passed to the retriever to fetch relevant documents. Those documents (and original inputs) are then passed to an LLM to generate a response
