人类认知辅助防御GAN 保护反向实例 (HAD-GAN: A Human-perception Auxiliary Defense GAN to Defend Adversarial Examples)

from arxiv, There is some error in our work. For example,"Notably, we linked a fully connected discriminant network in parallel at the penultimate level of the target classifier." (section 3.2) Incorrect description of the network structure can mislead readers. For example, "associate GAN with human imagination" is not true.(section 1)

Adversarial examples reveal the vulnerability and unexplained nature of neural networks. Studying the defense of adversarial examples is of considerable practical importance. Most adversarial examples that misclassify networks are often undetectable by humans. In this paper, we propose a defense model to train the classifier into a human-perception classification model with shape preference. The proposed model comprising a texture transfer network (TTN) and an auxiliary defense generative adversarial networks (GAN) is called Human-perception Auxiliary Defense GAN (HAD-GAN). The TTN is used to extend the texture samples of a clean image and helps classifiers focus on its shape. GAN is utilized to form a training framework for the model and generate the necessary images. A series of experiments conducted on MNIST, Fashion-MNIST and CIFAR10 show that the proposed model outperforms the state-of-the-art defense methods for network robustness. The model also demonstrates a significant improvement on defense capability of adversarial examples.
