Adaptive momentum variance for attention-guided sparse adversarial attacks

作者:

Highlights:

• Our method considers two kinds of momentum variances, namely the forward momentum variance and the historical momentum variance, to adaptively stabilize the attack direction and escape from local optima.

• We refine the generated perturbation matrix to prevent the overfitting of the adversarial examples.

• We use the attention mechanism to perform the transfer-based sparse attack and assist in studying the relationship between the number of pixels attacked and attack performance.
