Learning-Based Pricing and Matching for Two-Sided Queues

no code implementations17 Mar 2024 Zixian Yang, Lei Ying

We prove that our proposed algorithm yields a sublinear regret $\tilde{O}(T^{5/6})$ and queue-length bound $\tilde{O}(T^{2/3})$, where $T$ is the time horizon.

Online Nonstochastic Control with Adversarial and Static Constraints

no code implementations5 Feb 2023 Xin Liu, Zixian Yang, Lei Ying

This subroutine also achieves the state-of-the-art regret and constraint violation bounds for constrained online convex optimization problems, which is of independent interest.

Learning While Scheduling in Multi-Server Systems with Unknown Statistics: MaxWeight with Discounted UCB

no code implementations2 Sep 2022 Zixian Yang, R. Srikant, Lei Ying

We prove that under our algorithm the asymptotic average queue length is bounded by one divided by the traffic slackness, which is order-wise optimal.

Exploration, Exploitation, and Engagement in Multi-Armed Bandits with Abandonment

no code implementations26 May 2022 Zixian Yang, Xin Liu, Lei Ying

To understand the exploration, exploitation, and engagement in these systems, we propose a new model, called MAB-A where "A" stands for abandonment and the abandonment probability depends on the current recommended item and the user's past experience (called state).
