Fgm fast gradient method
WebAug 1, 2024 · To address the mentioned issues, we introduce an adaptive gradient-based adversarial attack method named Adaptive Iteration Fast Gradient Method (AI-FGM), which focuses on seeking the input’s preceding gradient and adjusts the accumulation of perturbed entity adaptively for performing adversarial attacks. WebFGM (Fast Gradient Method): ICLR2024. FSGM是每个方向上都走相同的一步,Goodfellow后续提出的FGM则是根据具体的梯度进行scale,得到更好的对抗样本: ... PGD (Projected Gradient Descent): ICLR2024. FGM直接通过epsilon参数一下子算出了对抗扰动,这样得到的可能不是最优的。
