Webb20 aug. 2024 · While CNNs perform better when trained from scratch, ViTs gain strong benifit when pre-trained on ImageNet and outperform their CNN counterparts using self-supervised learning and sharpness-aware minimizer optimization method on the large datasets. 1 View 1 excerpt, cites background Transformers in Medical Imaging: A Survey Webb27 maj 2024 · However, SAM-like methods incur a two-fold computational overhead of the given base optimizer (e.g. SGD) for approximating the sharpness measure. In this paper, we propose Sharpness-Aware Training for Free, or SAF, which mitigates the sharp landscape at almost zero additional computational cost over the base optimizer.
Webb28 jan. 2024 · The recently proposed Sharpness-Aware Minimization (SAM) improves generalization by minimizing a perturbed loss defined as the maximum loss within a neighborhood in the parameter space. However, we show that both sharp and flat minima can have a low perturbed loss, implying that SAM does not always prefer flat minima. …
