Researchers propose Asymptotic Unbiased Sampling with respect to iterations to accelerate Sharpness-Aware Minimization (SAM).AUSAM probabilistically samples a subset of data points based on the Gradient Norm of each Sample (GNS).The method consistently accelerates SAM across various tasks and networks, achieving a speedup of over 70%.AUSAM is better suited for SAM and excels in maintaining performance compared to recent dynamic data pruning methods.
