Diffusion models' creative generation and mode recovery analyzed in new arXiv papers

Two new research papers published on arXiv delve into the intricacies of diffusion models. The first paper, "On the Interpolation Effect of Score Smoothing in Diffusion Models," hypothesizes that the creative data generation capabilities of these models stem from learning a smoothed version of the empirical score function. The second paper, "Diffusion models recover accurate mixture weights despite score function insensitivity," addresses a puzzling behavior where diffusion models may fail to learn correct relative mode amplitudes, proposing a framework to understand and improve mixture weight recovery.

    On the Interpolation Effect of Score Smoothing in Diffusion Models

    arXiv:2502.19499v4 Announce Type: replace-cross Abstract: Diffusion models have achieved remarkable progress in various domains with an intriguing ability to produce new data that do not exist in the training set. In this work, we study the hypothesis that such creativity arises …

    Diffusion models recover accurate mixture weights despite score function insensitivity

    arXiv:2607.15485v1 Announce Type: cross Abstract: Score-based generative models exhibit a puzzling behavior: they often appear to cover all modes of a target multimodal distribution and yet may fail to learn the correct relative mode amplitudes, which can be interpreted as mixtur…
