Scalable Deep Reinforcement Learning for Ride-Hailing

Jiekun Feng, Mark Gluzman, J. G. Dai

Ride-hailing services, such as Didi Chuxing, Lyft, and Uber, arrange thousands of cars to meet ride requests throughout the day. We consider a Markov decision process (MDP) model o…

Newton-Step-Based Hard Thresholding Algorithms for Sparse Signal Recovery

Nan Meng, Yun-Bin Zhao

Sparse signal recovery or compressed sensing can be formulated as certain sparse optimization problems. The classic optimization theory indicates that the Newton-like method often…
