LightCRS: lightweight query-conditioned multi-domain multimodal conversational recommender

LightCRS is a lightweight framework that precomputes frozen multimodal product representations offline and uses a compact 5.3M-parameter query-conditioned cross-attention module plus an inter-candidate Transformer to fuse evidence online for unified multi-domain conversational recommendation. Evaluated on MM-R2A-25, a new 25-domain benchmark pairing Reddit recommendation-seeking conversations with Amazon product listings, LightCRS achieves state-of-the-art average HR@1, NDCG@5, and MRR, boosting HR@1 by 35.4% over the strongest baseline and reducing per-query latency by 266×.

Counterfactual Neighborhood Risk Fields (CNRF) for selective safety in vision‑language models

The paper introduces Counterfactual Neighborhood Risk Fields (CNRF), a representation-based, evidence-grounded framework that builds context-matched benign–harmful counterfactual pairs to derive capability-related risk directions and separately estimate neighborhood support. CNRF enables selective intervention (routing requests for same-victim review or producing constrained alternatives) and reports 86.06–89.30% macro defense success across three VLMs and five multimodal jailbreak families while retaining substantial benign-task utility.
