Tony Frank Sandrine Bonnaire 1812 This repository contains code for the paper "why diffusion models don't memorize: the role of implicit dynamical regularization in training" by t. bonnaire, r. urfin, g. biroli and m. mézard. Through an interdisciplinary approach combining statistical physics, computer science, and numerical experiments, tony bonnaire and his collaborators have made a key discovery about how diffusion models learn: the quantitative identification of two distinct and predictable timescales — an initial phase of generalization that is independent of.

Thanks to its newly tilted orbit around the sun, the esa led solar orbiter spacecraft is the first to image the sun’s poles from outside the ecliptic plane. this unique viewing angle will change our understanding of the sun’s magnetic field, the solar cycle and the workings of space weather. In this work, we investigate the role of the training dynamics in the transition from generalization to memorization. through extensive experiments and theoretical analysis, we identify two distinct timescales: an early time τ gen at which models begin to generate high quality samples, and a later time τ mem beyond which memorization emerges. Bonnaire et al. provide a compelling, mechanically transparent explanation for the generalization capabilities of diffusion models. by shifting the focus from architectural constraints to training dynamics, they highlight that “time” is a regularizer as potent as weight decay or dropout. In these lecture notes we present different methods and concepts developed in statistical physics to analyze gradient descent dynamics in high dimensional non convex landscapes.
