Diffusion Models Theory Advanced Under Manifold Hypothesis

Researchers have theoretically analyzed Denoising Diffusion Probabilistic Models (DDPMs) under the manifold hypothesis, which posits that high-dimensional data resides on lower-dimensional manifolds. The study proves that DDPMs achieve score learning rates independent of ambient dimension and sampling complexity rates independent of ambient dimension concerning Wasserstein distance. This framework connects diffusion models to the theory of extrema of Gaussian Processes. AI
