Approximation Families and the Statistical Efficiency of Denoising Score Matching
arXiv:2610.36205v1 Announce Type: new Abstract: We study score matching over finite-dimensional approximation spaces generated by gradients of eigenfunctions of the infinitesimal generator of a forward diffusion. We compare polynomial approximation under one-dimensional Ornstein-Uhlenbeck flow with…
