Does 1/2-Tsallis-INF Also Work Well for Best-Arm Identification?

Jingxin Zhan, Yuze Han, Zhihua Zhang

Regret minimization (RM) and best-arm identification (BAI) are two fundamental objectives in multi-armed bandits. Among regret-minimizing algorithms, -Tsallis-INF is a canonic…

Decoupled Functional Central Limit Theorems for Two-Time-Scale Stochastic Approximation

Yuze Han, Xiang Li, Jiadong Liang +1

In two-time-scale stochastic approximation (SA), two iterates are updated at different rates, governed by distinct step sizes, with each update influencing the other. Previous stud…
