- This note aggregates different RAG improvements and replacements, organized by the stage of the RAG pipeline each method innovates on.
# Categories
- Query Transformation
- Reshape or expand the query before retrieval (HyDE and its variants).
- RAG Indexing Strategies
- Enrich chunks, impose structure, or precompute reasoning at index time (Contextual Retrieval, RAPTOR, BookRAG, IndexRAG, QB-RAG).
- Advanced Retrieval Strategies
- Innovate on the retrieval mechanism itself (Page Index, LATTICE, GrepRAG, RuleRAG).
- Adaptive & Agentic RAG
- Add dynamic control over when, what, and how to retrieve (Skill-RAG, RouteRAG).
- Context Pruning
- LLM Context Pruning Improving RAG and Agentic AI Systems ( Link)
- [[Provence: efficient and robust context pruning ]]
