An Adaptive Method for Contextual Stochastic Multi-armed Bandits with Rewards Generated by a Linear Dynamical System

Jonathan Gornet, Mehdi Hosseinzadeh, Bruno Sinopoli

Online decision-making can be formulated as the popular stochastic multi-armed bandit problem where a learner makes decisions (or takes actions) to maximize cumulative rewards coll…

A Control Theory inspired Exploration Method for a Linear Bandit driven by a Linear Gaussian Dynamical System

Jonathan Gornet, Yilin Mo, Bruno Sinopoli

The paper introduces a linear bandit environment where the reward is the output of a known Linear Gaussian Dynamical System (LGDS). In this environment, we address the fundamental…

An Exploration-free Method for a Linear Stochastic Bandit Driven by a Linear Gaussian Dynamical System

Jonathan Gornet, Yilin Mo, Bruno Sinopoli

In stochastic multi-armed bandits, a major problem the learner faces is the trade-off between exploration and exploitation. Recently, exploration-free methods -- methods that commi…

Restless Bandit Problem with Rewards Generated by a Linear Gaussian Dynamical System

Jonathan Gornet, Bruno Sinopoli

Decision-making under uncertainty is a fundamental problem encountered frequently and can be formulated as a stochastic multi-armed bandit problem. In the problem, the learner inte…
