在这种情况下,FGSM攻击是以 错误分类 为目标的 白盒攻击 。 有了这些背景信息,我们现在可以详细讨论攻击(attack)了。 快速梯度符号攻击(Fast Gradient Sign Attack) 迄今为止,第一次也是最流行的对抗性攻击(adversarial attacks)之一被称为 快速梯度符号攻击(FGSM) , 古德费尔特对此进行了描述: Explaining and Harnes...
Pytorch实现FGSM(Fast Gradient Sign Attack) 1. 相关说明 最近在整理相关实验代码的时候,无意中需要重新梳理下对抗攻击里的FGSM,于是自己参考网上的一些资料以及自己的心得写下这篇文章,用来以后回忆。 2. 相关简述 快速梯度标志攻击(FGSM),是迄今为止最早和最受欢迎的对抗性攻击之一,它由 Goodfellow 等人在[Explaini...

However, due to the majority voting, the proposed HEM_Net model could improve its robustness against FGSM attacks, indicating that the ensemble can lessen deception by FGSM adversarial instances. This generally holds even as the perturbation level of the FGSM attack increases....
然后,作者在总结之前的工作时提到了两种基于梯度的攻击方法(但不是针对于图神经网络的),分别为:FastGradientSignMethod(FGSM)attack和Jacobian−basedSaliencyMapApproach(JSMA)attack。 FGSM: η=ϵsign(∇Jθ(x,l)),其中ϵ表示扰动的大小,sign获取梯度的符号。

快速梯度标志攻击(FGSM),是迄今为止最早和最受欢迎的对抗性攻击之一,它由 Goodfellow 等人在[Explaining and Harnessing Adversarial Examples] (https://arxiv.org/abs/1412.6572)中提出,是一种简单但是有效的对抗样本生成算法。它旨在通过利用模型学习的方式和渐变来攻击神经 网络。这个想法很简单,攻击调整输入数据以基...
The FGSM attack is applied to three pre-trained image classifier CNN architectures: DenseNet 201, Inception V3, and RegNetY 400MF, using randomly selected images from the ImageNet dataset. The accuracy of these models is measured both in the absence and presence of the attack to illustrate the...
