Achieving Optimality Gap in Restless Bandits through Gaussian Approximation
Chen Yan, Weina Wang, Lei Ying
We study the finite-horizon Restless Multi-Armed Bandit (RMAB) problem with homogeneous arms. Prior work has shown that when an RMAB satisfies a non-degeneracy condition, Linea…
On the Global Convergence of Risk-Averse Natural Policy Gradient Methods with Expected Conditional Risk Measures
Xian Yu, Lei Ying
Risk-sensitive reinforcement learning (RL) has become a popular tool for controlling the risk of uncertain outcomes and ensuring reliable performance in highly stochastic sequentia…
On Universal Scaling of Distributed Queues under Load Balancing
Xin Liu, Lei Ying
This paper considers the steady-state performance of load balancing algorithms in a many-server system with distributed queues. The system has servers, and each server maintain…
A Simple Steady-State Analysis of Load Balancing Algorithms in the Sub-Halfin-Whitt Regime
Xin Liu, Lei Ying
This paper studies a class of load balancing algorithms for many-server ( servers) systems assuming finite buffer with size (i.e. a server can have at most one job in serv…
