Demystifying Foreground-Background Memorization in Diffusion Models

AAAI 2026technical

Diffusion models (DMs) memorize training images and can reproduce near-duplicates during generation. Current detection methods identify verbatim memorization but fail to capture two critical aspects: quantifying partial memorization occurring in small image regions, and memorization patterns beyond

Machine Unlearning Fails to Remove Data Poisoning Attacks

ICLR 2025poster

We revisit the efficacy of several practical methods for approximate machine unlearning developed for large-scale deep learning. In addition to complying with data deletion requests, one often-cited potential application for unlearning methods is to remove the effects of poisoned data. We experiment…

Hidden Poison: Machine Unlearning Enables Camouflaged Poisoning Attacks

NeurIPS 2023poster

We introduce camouflaged data poisoning attacks, a new attack vector that arises in the context of machine unlearning and other settings when model retraining may be induced. An adversary first adds a few carefully crafted points to the training dataset such that the impact on the model's prediction…
