arXiv:2605.12597v2 Announce Type: replace-cross Abstract: Computational sampling has been central to the sciences since the mid-20th century. While machine-learning-based approaches have recently enabled major advances, their behavior remains poorly understood, with limited theoretical control over when and why they succeed. Here we provide such insight for diffusion models-a class of generative schemes highly effective in practice-by analyzing their application to the $O(n)$ model of statistical field theory in the Gaussian limit $n \to \infty$. In this analytically tractable setting, we show
This research is surfacing now as the practical successes of diffusion models drive deeper theoretical inquiry into their underlying mechanics and limitations.
Understanding the 'critical slowing down' in diffusion models provides crucial insights for optimizing their performance and reliability, influencing future AI development.
The theoretical control over diffusion model behavior is enhanced, allowing for more targeted improvements and potentially identifying fundamental limits.
