A New RAG technique - Dynamic Section Retrieval! You can then do GraphRAG-like retrieval (two-pass retrieval): retrieve chunks, look up the attached section metadata, and then do a second call to return all chunks that match the section ID. Repo: https://t.co/VERgD2itrJ https://t.co/E13ileMwy6
Pretty excited about this new RAG technique I cooked up 🧑🍳 A top issue with RAG chunking is it splits the document into fragmented pieces, causing top-k retrieval to return partial context. Also most documents have multiple hierarchies of sections: top-level sections,… https://t.co/JFAp3wUe1C https://t.co/z6a9mxdbcU
Simple chunking strategies outperform sophisticated semantic chunking methods for RAG, as per this paper, Original Problem 🤔: RAG systems commonly use semantic chunking to split documents into coherent segments, aiming to improve retrieval performance. However, there's no… https://t.co/tZAIL7FKJo
The recent introduction of TurboRAG represents a significant advancement in retrieval-augmented generation (RAG) technology. This new system accelerates RAG processes by utilizing precomputed key-value caches for chunked text, promising a speed increase of nine times. Researchers have identified that simple chunking strategies can outperform more complex semantic chunking methods, addressing a common issue where traditional RAG systems fragment documents into incoherent segments. Additionally, a new technique called Dynamic Section Retrieval has been proposed, which enhances retrieval accuracy by allowing a two-pass retrieval process that leverages section metadata. These developments indicate a shift towards more efficient and coherent document processing in RAG applications.
