A Stochastic Composite Augmented Lagrangian Method For Reinforcement Learning

Yongfeng Li, Mingming Zhao, Weijie Chen +1

In this paper, we consider the linear programming (LP) formulation for deep reinforcement learning. The number of the constraints depends on the size of state and action spaces, wh…

Enhance Curvature Information by Structured Stochastic Quasi-Newton Methods

Minghan Yang, Dong Xu, Hongyu Chen +2

In this paper, we consider stochastic second-order methods for minimizing a finite summation of nonconvex functions. One important key is to find an ingenious but cheap scheme to i…

Low-rank Matrix Optimization Using Polynomial-filtered Subspace Extraction

Yongfeng Li, Haoyang Liu, Zaiwen Wen +1

In this paper, we study first-order methods on a large variety of low-rank matrix optimization problems, whose solutions only live in a low dimensional eigenspace. Traditional firs…

A Semi-smooth Newton Method for Solving Semidefinite Programs in Electronic Structure Calculations

Yongfeng Li, Zaiwen Wen, Chao Yang +1

The ground state energy of a many-electron system can be approximated by an variational approach in which the total energy of the system is minimized with respect to one and two-bo…
