Exploring Hierarchical RAG: An Advanced Technique for Robust Information Retrieval
In the ever-evolving landscape of information retrieval and Large Language Models (LLMs), Retrieval-Augmented Generation (RAG) is becoming a de facto mechanism to quickly answer questions across a broad range of topics. However, the responses can often suffer from inaccuracies when they predominantly rely on extracting chunks of information with keyword matching only.Hierarchical RAG (HRAG) is a technique to improve the accuracy and relevance of responses.HRAG builds on traditional RAG by using a to organize and find information at different levels,...
