MoECLIP: Patch-Specialized Experts for Zero-shot Anomaly Detection

MoECLIP addresses the limitations of patch-agnostic designs in Zero-Shot Anomaly Detection by introducing a Mixture-of-Experts architecture that dynamically routes image patches to specialized LoRA experts, enhanced by Frozen Orthogonal Feature Separation and an ETF loss to ensure distinct and maximally equiangular representations, thereby achieving state-of-the-art performance across diverse industrial and medical benchmarks.

Beyond Accuracy: Evaluating Visual Grounding In Multimodal Medical Reasoning

This paper introduces a counterfactual evaluation framework revealing that while reinforcement learning with verifiable rewards improves accuracy on medical VQA benchmarks, it often degrades genuine visual grounding by enabling models to rely on text shortcuts and hallucinate visual reasoning, necessitating new evaluation metrics and training objectives that explicitly enforce visual dependence.

Geographically-Weighted Weakly Supervised Bayesian High-Resolution Transformer for 200m Resolution Pan-Arctic Sea Ice Concentration Mapping and Uncertainty Estimation using Sentinel-1, RCM, and AMSR2 Data

This study proposes a novel Geographically-Weighted Weakly Supervised Bayesian High-Resolution Transformer that fuses Sentinel-1, RCM, and AMSR2 data to generate 200m resolution pan-Arctic sea ice concentration maps with reliable uncertainty estimates, effectively overcoming challenges related to subtle feature extraction, inexact labels, and data heterogeneity.
