But standard RAG has a fundamental limitation: it treats each query independently, with no memory of past retrievals or ability to connect information across documents. <strong>HippoRAG</strong> takes inspiration from the human brain&rsquo;s hippocampus to overcome this, creating a long-term memory system that dramatically improves multi-hop question answering.</p> <p>Published at NeurIPS 2024 and available at <a href="https://github.com/OSU-NLP-Group/HippoRAG">github.com/OSU-NLP-Group/HippoRAG</a>, HippoRAG combines LLMs with knowledge graphs in a framework modeled on the hippocampal indexing theory of human memory. The result is a RAG system that builds a persistent knowledge structure from documents, enabling it to answer complex questions that require connecting information across multiple sources &ndash; achieving approximately 20% improvement over standard RAG on multi-hop QA benchmarks.</p>
