Query: Decision-based Black-box Attack Against Vision Transformers via
  Patch-wise Adversarial Removal   Vision transformers (ViTs) have demonstrated impressive performance and
stronger adversarial robustness compared to Deep Convolutional Neural Networks
(CNNs). On the one hand, ViTs' focus on global interaction between individual
patches reduces the local noise sensitivity of images. On the other hand, the
existing decision-based attacks for CNNs ignore the difference in noise
sensitivity between different regions of the image, which affects the
efficiency of noise compression. Therefore, validating the black-box
adversarial robustness of ViTs when the target model can only be queried still
remains a challenging problem. In this paper, we propose a new decision-based
black-box attack against ViTs termed Patch-wise Adversarial Removal (PAR). PAR
divides images into patches through a coarse-to-fine search process and
compresses the noise on each patch separately. PAR records the noise magnitude
and noise sensitivity of each patch and selects the patch with the highest
query value for noise compression. In addition, PAR can be used as a noise
initialization method for other decision-based attacks to improve the noise
compression efficiency on both ViTs and CNNs without introducing additional
calculations. Extensive experiments on ImageNet-21k, ILSVRC-2012, and
Tiny-Imagenet datasets demonstrate that PAR achieves a much lower magnitude of
perturbation on average with the same number of queries.
