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 $μ$ with density $\propto e^{- V}$ for some potential function $V : R^{d} \to R$ with query access to $V$ and $\nabla…

On the Problem of Best Arm Retention

Houshuang Chen, Yuchen He, Chihao Zhang

This paper presents a comprehensive study on the problem of Best Arm Retention (BAR), which has recently found applications in streaming algorithms for multi-armed bandits. In the…

On the query complexity of sampling from non-log-concave distributions

Yuchen He, Chihao Zhang

We study the problem of sampling from a $d$ -dimensional distribution with density $p (x) \propto e^{- f (x)}$ , which does not necessarily satisfy good isoperimetric conditions. Specifi…
