Beyond Topical Similarity: Contrastive Evidence Retrieval with Interpretable Attention Alignment in RAG 事件

Beyond Topical Similarity: Contrastive Evidence Retrieval with Interpretable Attention Alignment in RAG arXiv:2606.01482v1 Announce Type: new Abstract: Ensuring factuality and interpretability in RAG remains an open and urgent problem. We introduce Contrastive Evidence Rationale Attention (CERA), the first retrieval framework to employ subjectivity-based hard negative selection and inject an evidential inductive bias into contrastive learning through an auxiliary attention alignment loss.
