Rate-Optimal Contextual Online Matching Bandit

no code implementations7 May 2022 Yuantong Li, Chi-Hua Wang, Guang Cheng, Will Wei Sun

Existing works focus on multi-armed bandit with static preference, but this is insufficient: the two-sided preference changes as along as one-side's contextual information updates, resulting in non-static matching.

Residual Bootstrap Exploration for Stochastic Linear Bandit

no code implementations23 Feb 2022 Shuang Wu, Chi-Hua Wang, Yuantong Li, Guang Cheng

We propose a new bootstrap-based online algorithm for stochastic linear bandit problems.

Online Bootstrap Inference For Policy Evaluation in Reinforcement Learning

no code implementations8 Aug 2021 Pratik Ramprasad, Yuantong Li, Zhuoran Yang, Zhaoran Wang, Will Wei Sun, Guang Cheng

The recent emergence of reinforcement learning has created a demand for robust statistical inference methods for the parameter estimates computed using these algorithms.

Online Forgetting Process for Linear Regression Models

no code implementations3 Dec 2020 Yuantong Li, Chi-Hua Wang, Guang Cheng

Motivated by the EU's "Right To Be Forgotten" regulation, we initiate a study of statistical data deletion problems where users' data are accessible only for a limited period of time.
