Best Arm Identification in Restless Markov Multi-Armed Bandits

P. N. Karthik, Kota Srinivas Reddy, Vincent Y. F. Tan

We study the problem of identifying the best arm in a multi-armed bandit environment when each arm is a time-homogeneous and ergodic discrete-time Markov process on a common, finit…

Learning to Detect an Odd Restless Markov Arm with a Trembling Hand

P. N. Karthik, Rajesh Sundaresan

This paper studies the problem of finding an anomalous arm in a multi-armed bandit when (a) each arm is a finite-state Markov process, and (b) the arms are restless. Here, anomaly…

Detecting an Odd Restless Markov Arm with a Trembling Hand

P. N. Karthik, Rajesh Sundaresan

In this paper, we consider a multi-armed bandit in which each arm is a Markov process evolving on a finite state space. The state space is common across the arms, and the arms are…

Learning to Detect an Odd Markov Arm

P. N. Karthik, Rajesh Sundaresan

A multi-armed bandit with finitely many arms is studied when each arm is a homogeneous Markov process on an underlying finite state space. The transition law of one of the arms, re…
