Pareto-Improving Adversarial Attacks with Primal-Dual Regularization
The stealthy transfer attack ST is introduced, a plug-in primal-dual wrapper that adds an $L_\infty$ saturation regularizer to the standard constrained objective and resolves it through a two-step primal-dual update, confirming that the latent imperceptibility advantage of strong transfer attacks can be unlocked by a p...
