Hi-Q: Hierarchical Evidence-guided Query Refinement for Multi-Hop Question Answering
This solves a real problem in RAG pipelines: knowing when to stop refining a query versus digging deeper. The evidence-conditioned approach is cleaner than blind iteration. If you're building multi-step retrieval systems, this is the kind of signal-based decision-making that prevents infinite loops. The technique is sound but incremental on existing work.
