Federated Estimation of Causal Effects from Observational Data

no code implementations31 May 2021 Thanh Vinh Vo, Trong Nghia Hoang, Young Lee, Tze-Yun Leong

Many modern applications collect data that comes in federated spirit, with data kept locally and undisclosed.

Causal Inference Gaussian Processes

Adaptive Multi-Source Causal Inference

no code implementations31 May 2021 Thanh Vinh Vo, Pengfei Wei, Trong Nghia Hoang, Tze-Yun Leong

The proposed method can infer causal effects in the target population without prior knowledge of data discrepancy between the additional data sources and the target.

Hierarchical Reinforcement Learning in StarCraft II with Human Expertise in Subgoals Selection

no code implementations8 Aug 2020 Xinyi Xu, Tiancheng Huang, Pengfei Wei, Akshay Narayan, Tze-Yun Leong

This work is inspired by recent advances in hierarchical reinforcement learning (HRL) (Barto and Mahadevan 2003; Hengst 2010), and improvements in learning efficiency from heuristic-based subgoal selection, experience replay (Lin 1993; Andrychowicz et al. 2017), and task-based curriculum learning (Bengio et al. 2009; Zaremba and Sutskever 2014).

Subdomain Adaptation with Manifolds Discrepancy Alignment

no code implementations6 May 2020 Pengfei Wei, Yiping Ke, Xinghua Qu, Tze-Yun Leong

Specifically, we propose to use low-dimensional manifold to represent subdomain, and align the local data distribution discrepancy in each manifold across domains.
