AWS Implements HippoRAG — Neurobiologically Inspired RAG on Bedrock, Neptune, and Personalized PageRank

AWS Machine Learning Blog·medium signal

AWS walks through building HippoRAG, a retrieval-augmented generation approach inspired by the hippocampus that combines Amazon Bedrock LLMs, Amazon Neptune graph storage, and personalized PageRank for multi-hop retrieval. For builders, it's an implementation-depth template for graph-based RAG that goes beyond flat vector search.
