Demystifying Adversarial Robustness in Diffusion Models: Compression, Randomness, and Geometry
Quick summary
arXiv:2505.22839v2 Announce Type: replace-cross Abstract: Recent studies suggest that diffusion models significantly improve the empirical adversarial robustness of deep neural network models. While intuitive explanations have been proposed, the mechanisms underlying diffusion-based robustness remain largely unclear. This work aims to demystify how diffusion models improve adversarial robustness. We observe that diffusion models surprisingly increase the $\ell_p$ distance to clean samples, thus rejecting the hypothesis that purification denoises perturbed images closer to the clean ones.
