Breaking the Curse of Dimensionality: Diffusion Models Efficiently Learn Low-Dimensional Distributions
arXiv:2409.02426v5 Announce Type: replace Abstract: Despite their empirical success across a wide range of generative tasks, the fundamental principles underlying the ability of diffusion models to learn data distributions are poorly understood. In this work, we develop a new mathematical framework that explains how diffusion models can effectively learn low-dimensional distributions from a finite number of training samples without suffering from the curse of dimensionality. Specifically, motivated by the intrinsic low-dimensional structure of image data, we theoretically analyze a setting in

A deeper theoretical understanding of diffusion models can lead to more efficient, reliable, and powerful AI systems, potentially accelerating progress in various generative tasks.
The ability of diffusion models to efficiently learn low-dimensional distributions without the curse of dimensionality is now theoretically supported, enabling more targeted development and application.
