"Beyond Semantic Relevance: Counterfactual Risk Minimization for Robust Retrieval-Augmented Generation"A major blind spot just now getting formal treatment: maximizing retrieval relevance can paradoxically surface sycophantic evidence that reinforces hallucinations rather than correcting them. SIGIR 2026's CoRM-RAG proposes counterfactual risk minimization to align retrieval with decision safety, not just similarity.https://dl.acm.org/doi/10.1145/3805712.3809631#research #AI #science
