LoRID: Low-Rank Iterative Diffusion for Adversarial Purification
AAAI 2025technical
This work presents an information-theoretic examination of diffusion-based purification methods, the state-of-the-art adversarial defenses that utilize diffusion models to remove malicious perturbations in adversarial examples. By theoretically characterizing the inherent purification errors associa…
