Value Gradient Sampler: Learning Invariant Value Functions for Equivariant Diffusion Sampling

Himchan Hwang, Hyeokju Jeong, Dong Kyu Shin +4

We propose the Value Gradient Sampler (VGS), a diffusion sampler parameterized by value functions. VGS generates samples from an unnormalized target density (i.e., energy) by evolv…
