Adversarial Bandits with Corruptions: Regret Lower Bound and No-regret Algorithm

no code implementations • NeurIPS 2020 • Lin Yang, Mohammad Hajiesmaili, Mohammad Sadegh Talebi, John C. S. Lui, Wing Shing Wong

We characterize the regret of ExpRb as a function of the corruption budget and show that for the case of a known corruption budget, the regret of ExpRb is tight.

Recursive Exponential Weighting for Online Non-convex Optimization

no code implementations • 13 Sep 2017 • Lin Yang, Cheng Tan, Wing Shing Wong

In this paper, we investigate the online non-convex optimization problem which generalizes the classic {online convex optimization problem by relaxing the convexity assumption on the cost function.
