Adversarial noise
WebMar 1, 2024 · Inspired by PixelDP, the authors in Ref. [72] further propose to directly add random noise to pixels of adversarial examples before classification, in order to eliminate the effects of adversarial perturbations. Following the theory of Rényi divergence, it proves that this simple method can upper-bound the size of the adversarial perturbation ... Weban adversary flips the labels of some OPTfraction of the data and we try to match the predictions of h. This flipping of the labels can be interpreted as noise. In this lecture, we consider a dif-ferent model of noise that is more benign, where the label of every instance is flipped with equal probability. 1 Random Classification Noise (RCN ...
