The RAG system tutorial has been released! This system is based on arXiv papers as a context source and provides links to the source papers used in generating answers. Tutorial link: https://colab.research.google.com/drive/1Lc8eq8P87JjzUhbYb33_c7h7njsWb-hn#scrollTo=eCSBhP4FxOg3  . The tutorial thoroughly demonstrates the process of implementing the RAG system, including obtaining paper text, preprocessing and chunking PDF documents using Unstructured, creating a ChromaDB retriever, setting up RAG with LangChain, and defining the response link function.
