Transferred Q-learning

no code implementations9 Feb 2022 Elynn Y. Chen, Michael I. Jordan, Sai Li

We consider $Q$-learning with knowledge transfer, using samples from a target reinforcement learning (RL) task as well as source samples from different but related RL tasks.

Improving Out-of-Distribution Robustness via Selective Augmentation

2 code implementations2 Jan 2022 Huaxiu Yao, Yu Wang, Sai Li, Linjun Zhang, Weixin Liang, James Zou, Chelsea Finn

Machine learning algorithms typically assume that training and test examples are drawn from the same distribution.

Targeting Underrepresented Populations in Precision Medicine: A Federated Transfer Learning Approach

no code implementations27 Aug 2021 Sai Li, Tianxi Cai, Rui Duan

With only a small number of communications across participating sites, the proposed method can achieve performance comparable to the pooled analysis where individual-level data are directly pooled together.
