Abstract: In order to attack state-of-the-art adversarial defense methods, an image adversarial attack algorithm based on high-dimensional features called FB-PGD(feature based projected gradient descent) is proposed. It increases the similarity between clean image features and target image features by adding perturbation to clean image iteratively, then adversarial examples will be generated. In the experimental section, by comparing with existing adversarial attack algorithms on different defense models, the result shows that this attack algorithm not only has strong attack performance in the previous defense methods but also increases attack success rate more than 20[WTB4]%[WTBZ] compared to common adversarial attack algorithms in two state-of-the-art defense methods on a variety of datasets. So, the adversarial attack algorithm can be used as a new benchmark to test defense.
