Minimax Optimality of Score-based Diffusion Models: Beyond the Density Lower Bound Assumptions

Kaihong Zhang, Caitlyn H. Yin, Feng Liang +1

We study the asymptotic error of score-based diffusion model sampling in large-sample scenarios from a non-parametric statistics perspective. We show that a kernel-based score esti…
