Key Points
- 1.Traditional RAG involves chunking and embedding documents into vectors stored in a database.
- 2.Vectorless RAG uses a structured JSON index, suitable for well-organized documents.
- 3.The choice between RAG types depends on document size and structure.
Summary
Understanding Traditional RAG
Traditional Retrieval-Augmented Generation (RAG) involves breaking down documents into chunks, embedding them into vectors, and storing them in a vector database like Pinecone or FAISS. User queries are then converted into vectors to perform similarity searches, retrieving relevant content based on vector proximity.
Implementation of Vectorless RAG
Vectorless RAG uses a hierarchical JSON structure generated by an LLM tree builder, which is optimal for structured documents. This method allows for direct indexing of content without the need for chunking, simplifying query responses by directly referencing the structured format.
When to Choose Each RAG Type
Choosing between traditional and vectorless RAG hinges on the characteristics of the document. Large, unstructured documents may not benefit from a vectorless approach, while structured documents with clear index pages can leverage the efficiency of JSON tree indexing.
Storage Solutions for JSON Structures
The JSON tree index created in vectorless RAG can be stored in various systems such as file systems, S3 buckets, or MongoDB. The flexibility in storage options allows for efficient access and retrieval for end-user queries.
