HyPE Framework: Boosting RAG Precision by 42% via Question-Question Matching
_reachsumit · x · 2026-08-03
To address the style mismatch between user queries and document text in RAG systems, the HyPE (Hypothetical Prompt Embeddings) framework is introduced.
- Core Approach: Shifts the generation of hypothetical content from query time to the indexing phase. It precomputes multiple hypothetical prompts for each data chunk during indexing and embeds the chunk in place of the prompt.
- Performance: Transforms retrieval into a question-question matching task, improving context precision by up to 42 percentage points and recall by up to 45 percentage points without introducing query-time latency.
- Compatibility: Fully compatible with existing RAG advancements like re-ranking, multi-vector retrieval, and query decomposition.
