Policy Gradient in Robust MDPs with Global Convergence Guarantee

1 code implementation20 Dec 2022 Qiuhao Wang, Chin Pang Ho, Marek Petrik

In contrast with prior robust policy gradient algorithms, DRPG monotonically reduces approximation errors to guarantee convergence to a globally optimal policy in tabular RMDPs.

Global Convergence of Over-parameterized Deep Equilibrium Models

no code implementations27 May 2022 Zenan Ling, Xingyu Xie, Qiuhao Wang, Zongpeng Zhang, Zhouchen Lin

A deep equilibrium model (DEQ) is implicitly defined through an equilibrium point of an infinite-depth weight-tied model with an input-injection.

Optimization Induced Equilibrium Networks

no code implementations27 May 2021 Xingyu Xie, Qiuhao Wang, Zenan Ling, Xia Li, Yisen Wang, Guangcan Liu, Zhouchen Lin

In this paper, we investigate an emerging question: can an implicit equilibrium model's equilibrium point be regarded as the solution of an optimization problem?

Implicit Normalizing Flows

1 code implementation ICLR 2021 Cheng Lu, Jianfei Chen, Chongxuan Li, Qiuhao Wang, Jun Zhu

Through theoretical analysis, we show that the function space of ImpFlow is strictly richer than that of ResFlows.
