Attend the IE Decision Systems Engineering Fall ’21 Seminar Series event that explores dynamic learning problems.

Revisiting Exploration versus Exploitation: Multi-Armed Bandits and Adaptive Control
Presented by P.R. Kumar, Texas A&M University

Friday, September 3, 2021
Noon
Attend via Zoom

Abstract

We consider the central problem of exploration versus exploitation that lies at the heart of several dynamic learning problems. We revisit the problem of regret in adaptive control and examine it in the light of recent interest in solving large-scale bandit problems. For bandit problems, we present a family of schemes that admits simple index policies whose regret performance appears to be near the best apparently currently available, and at low computational complexity per decision. This is joint work with Ping-Chun Hsieh, Yu-Heng Hung, Xi Liu, Akshay Mete, Rahul Singh, Anirban Bhattacharya and Le Xie.
