Friendly Sharpness-Aware Minimization

The code is the official implementation of our CVPR 2024 paper Friendly Sharpness-Aware Minimization.

Introduction

In this work, we reveal that the full gradient component in SAM’s adversarial weight perturbation does not contribute to generalization and, in fact, has undesirable effects. We then propose an efficient variant to mitigate these effects and solely utilize batch-wise stochastic gradient noise for weight perturbation. It further enhances the generalization performance of SAM and provides a fresh understanding on SAM's practical success.
