Provable Separations between Memorization and Generalization in Diffusion Models

ICLR 2026poster

Diffusion models have achieved remarkable success across diverse domains, but they remain vulnerable to memorization---reproducing training data rather than generating novel outputs. This not only limits their creative potential but also raises concerns about privacy and safety. While empirical stud…

Training-Free Adaptation of Diffusion Models via Doob's $h$-Transform

ICML 2026poster

Adaptation methods have been a workhorse for unlocking the transformative power of pre-trained diffusion models in diverse applications. Existing approaches often abstract adaptation objectives as a reward function and steer diffusion models to generate high-reward samples. However, these approaches…
