Researchers propose EGPO, a new framework that improves large reasoning models by incorporating uncertainty awareness into reinforcement learning training. The approach addresses the "uncertainty-reward mismatch" where current training methods treat high and low-confidence solutions equally, preventing models from developing better reasoning capabilities.
Researchers propose a novel Gaussian Process-based framework for medical image segmentation that explicitly models annotation bias and variability across multiple raters rather than encoding them implicitly. The approach improves uncertainty calibration in probabilistic predictions while maintaining segmentation accuracy, with quantifiable parameters reflecting individual annotator behavior.
Researchers propose an adversarial fine-tuning method for CLIP that addresses a critical gap in zero-shot classification: while perturbations degrade accuracy, they also suppress uncertainty estimates, causing overconfidence. The approach reparameterizes CLIP outputs as Dirichlet distribution parameters to jointly optimize for robustness and calibrated uncertainty, achieving competitive results across benchmarks.
