Deep into The Domain Shift: Transfer Learning through Dependence Regularization

1 code implementation31 May 2023 Shumin Ma, Zhiri Yuan, Qi Wu, Yiyan Huang, Xixu Hu, Cheuk Hang Leung, Dongdong Wang, Zhixiang Huang

This paper proposes a new domain adaptation approach in which one can measure the differences in the internal dependence structure separately from those in the marginals.

Moderately-Balanced Representation Learning for Treatment Effects with Orthogonality Information

no code implementations5 Sep 2022 Yiyan Huang, Cheuk Hang Leung, Shumin Ma, Qi Wu, Dongdong Wang, Zhixiang Huang

In this paper, we propose a moderately-balanced representation learning (MBRL) framework based on recent covariates balanced representation learning methods and orthogonal machine learning theory.

Robust Causal Learning for the Estimation of Average Treatment Effects

no code implementations5 Sep 2022 Yiyan Huang, Cheuk Hang Leung, Xing Yan, Qi Wu, Shumin Ma, Zhiri Yuan, Dongdong Wang, Zhixiang Huang

Theoretically, the RCL estimators i) are as consistent and doubly robust as the DML estimators, and ii) can get rid of the error-compounding issue.

Understanding Distributional Ambiguity via Non-robust Chance Constraint

no code implementations3 Jun 2019 Qi Wu, Shumin Ma, Cheuk Hang Leung, Wei Liu, Nanbo Peng

Without the boundedness constraint, the CCO problem is shown to perform uniformly better than the DRO problem, irrespective of the radius of the ambiguity set, the choice of the divergence measure, or the tail heaviness of the center distribution.
