Improved sampling algorithms and functional inequalities for non-log-concave distributions

Yuchen He, Zhehan Lei, Jianan Shao +1

We study the problem of sampling from a distribution $\hat{I}¼$ with density $\propto e^{-V}$ for some potential function $V:{\mathbb{R}}^d\to \mathbb{R}$ with query access to $V$ and $\nabl…
