Efficient Discriminative Joint Encoders for Large Scale Vision-Language Reranking

arXiv:2510.06820v2 Announce Type: replace-cross Abstract: Multimodal retrieval still leans on embedding-based models like CLIP for fast vector search over pre-computed image embeddings. Yet, unlike text retrieval, where joint-encoder rerankers are standard, comparable vision-language rerankers are largely absent. We find that…

Interpretable Failure Analysis in Multi-Agent Reinforcement Learning Systems

arXiv:2602.08104v2 Announce Type: replace-cross Abstract: Multi-Agent Reinforcement Learning (MARL) is increasingly deployed in safety-critical domains, yet methods for interpretable failure detection and attribution remain underdeveloped. We introduce a two-stage gradient-based framework that provides interpretable diagnostics for three critical failure analysis…
