Retrieval & RAG

Retrieval-augmented generation past the basics — advanced architectures, graph RAG, retrieval as an agent tool, RAG security.

  1. Advanced RAG Architectures
    The naive→modular→agentic RAG spectrum and the levers that matter — CRAG, Self-RAG, query transformation, fusion, reranking — all attacking the same garbage-in/confident-wrong-out failure.
  2. GraphRAG & Multi-Hop Retrieval
    Why flat top-k RAG cannot answer thematic or relational multi-hop queries, how Microsoft GraphRAG and iterative retrieve-reason loops solve it, and the cost/staleness heuristic for when not to.
