Exploring the Effect of Multi-step Ascent in Sharpness-Aware Minimization

no code implementations27 Jan 2023 Hoki Kim, Jinseong Park, Yujin Choi, Woojin Lee, Jaewook Lee

Recently, Sharpness-Aware Minimization (SAM) has shown state-of-the-art performance by seeking flat minima.

Stability Analysis of Sharpness-Aware Minimization

no code implementations16 Jan 2023 Hoki Kim, Jinseong Park, Yujin Choi, Jaewook Lee

Utilizing the qualitative theory of dynamical systems, we explain how SAM becomes stuck in the saddle point and then theoretically prove that the saddle point can become an attractor under SAM dynamics.
