Query: Feature Space Targeted Attacks by Statistic Alignment   By adding human-imperceptible perturbations to images, DNNs can be easily
fooled. As one of the mainstream methods, feature space targeted attacks
perturb images by modulating their intermediate feature maps, for the
discrepancy between the intermediate source and target features is minimized.
However, the current choice of pixel-wise Euclidean Distance to measure the
discrepancy is questionable because it unreasonably imposes a
spatial-consistency constraint on the source and target features. Intuitively,
an image can be categorized as "cat" no matter the cat is on the left or right
of the image. To address this issue, we propose to measure this discrepancy
using statistic alignment. Specifically, we design two novel approaches called
Pair-wise Alignment Attack and Global-wise Alignment Attack, which attempt to
measure similarities between feature maps by high-order statistics with
translation invariance. Furthermore, we systematically analyze the layer-wise
transferability with varied difficulties to obtain highly reliable attacks.
Extensive experiments verify the effectiveness of our proposed method, and it
outperforms the state-of-the-art algorithms by a large margin. Our code is
publicly available at https://github.com/yaya-cheng/PAA-GAA.
