Researchers have developed a new method to improve the reliability of CLIP, a model used for zero-shot image classification. The proposed technique addresses the issue where adversarial attacks not only reduce accuracy but also cause the model to become over-confident by suppressing uncertainty. By treating CLIP's outputs as parameters of a Dirichlet distribution, the method aligns the model's confidence with input difficulty, thereby restoring calibrated uncertainty and enhancing adversarial robustness while maintaining clean accuracy.
