Improving Adversarial Transferability via Intermediate-level Perturbation Decay. (arXiv:2304.13410v3 [cs.LG] UPDATED)

Intermediate-level attacks that attempt to perturb feature representations
following an adversarial direction drastically have shown favorable performance
in crafting transferable adversarial examples. Existing methods in this
category are normally formulated with two separate stages, where a directional
guide is required to be determined at first and the scalar projection of the
intermediate-level perturbation onto the directional guide is enlarged
thereafter. The obtained perturbation deviates from the guide inevitably in the
feature space, and it is revealed in this paper that …
