Discrete Optimal Transport: Rapid Convergence of Simulated Annealing Algorithms

Yuchen He, Tianhui Jiang, Sihan Wang +1

We develop a discrete optimal transport framework for analyzing simulated annealing algorithms on finite state spaces. Building on the discrete Wasserstein metric introduced by Maa…

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 -dimensional distribution with density , which does not necessarily satisfy good isoperimetric conditions. Specifi…

Understanding Memory-Regret Trade-Off for Streaming Stochastic Multi-Armed Bandits

Yuchen He, Zichun Ye, Chihao Zhang

We study the stochastic multi-armed bandit problem in the -pass streaming model. In this problem, the arms are present in a stream and at most arms and their statistic…

On Interpolating Experts and Multi-Armed Bandits

Houshuang Chen, Yuchen He, Chihao Zhang

Learning with expert advice and multi-armed bandit are two classic online decision problems which differ on how the information is observed in each round of the game. We study a fa…

Improved Algorithms for Bandit with Graph Feedback via Regret Decomposition

Yuchen He, Chihao Zhang

The problem of bandit with graph feedback generalizes both the multi-armed bandit (MAB) problem and the learning with expert advice problem by encoding in a directed graph how the…
