Learning to Adapt and Calibrate: Score Distribution Alignment for Few-Shot Uncertainty Prediction in Medical VLMs

AlignCP is proposed, a framework that reconciles supervised few-shot adaptation with conformal uncertainty estimation under non-exchangeability and learns a reweighted calibration distribution that reduces the score-level discrepancy between the labeled support set and the unlabeled query set.

GEOSTEER: Geodesic Optimization for Activation Steering in Large Language Models

GeoSteer is proposed, an optimization-based method for norm-preserving activation steering that consistently improves over state-of-the-art activation steering baselines and replaces predefined one-step edits with adaptive, geometry-aware optimization.
