Policy Gradient for Robust Markov Decision Processes

Qiuhao Wang, Shaohang Xu, Chin Pang Ho +1

We develop a generic policy gradient method with the global optimality guarantee for robust Markov Decision Processes (MDPs). While policy gradient methods are widely used for solv…

On Data-Driven Prescriptive Analytics with Side Information: A Regularized Nadaraya-Watson Approach

Prateek R. Srivastava, Yijie Wang, Grani A. Hanasusanto +1

We consider generic stochastic optimization problems in the presence of side information which enables a more insightful decision. The side information constitutes observable exoge…

Newton-type Multilevel Optimization Method

Chin Pang Ho, Michal Kocvara, Panos Parpas

Inspired by multigrid methods for linear systems of equations, multilevel optimization methods have been proposed to solve structured optimization problems. Multilevel methods make…
