用一个令人惊讶的简单防御来利用对抗性的例子

Harnessing adversarial examples with a surprisingly simple defense

Ali Borji

摘要:

我介绍了一个非常简单的方法来防御对抗性的例子。其基本思想是在测试时提高ReLU函数的斜率。在MNIST和CIFAR-10数据集上的实验证明了所提出的防御方法在非目标和目标环境中对许多强攻击的有效性。虽然这种方法可能不如最先进的对抗性防御有效,但它可以为理解和减轻对抗攻击提供见解。它也可以与其他防御措施结合使用。

英文摘要:

I introduce a very simple method to defend against adversarial examples. The basic idea is to raise the slope of the ReLU function at the test time. Experiments over MNIST and CIFAR-10 datasets demonstrate the effectiveness of the proposed defense against a number of strong attacks in both untargeted and targeted settings. While perhaps not as effective as the state of the art adversarial defenses, this approach can provide insights to understand and mitigate adversarial attacks. It can also be used in conjunction with other defenses.
