Optimal Strong Regret and Violation in Constrained MDPs via Policy Optimization

Francesco Emanuele Stradi, Matteo Castiglioni, Alberto Marchesi +1

We study online learning in \emph{constrained MDPs} (CMDPs), focusing on the goal of attaining sublinear strong regret and strong cumulative constraint violation. Differently from…

Bandits with Replenishable Knapsacks: the Best of both Worlds

Martino Bernasconi, Matteo Castiglioni, Andrea Celli +1

The bandits with knapsack (BwK) framework models online decision-making problems in which an agent makes a sequence of decisions subject to resource consumption constraints. The tr…

A Unifying Framework for Online Optimization with Long-Term Constraints

Matteo Castiglioni, Andrea Celli, Alberto Marchesi +2

We study online learning problems in which a decision maker has to take a sequence of decisions subject to long-term constraints. The goal of the decision maker is to maximize…

Sequential Information Design: Learning to Persuade in the Dark

Martino Bernasconi, Matteo Castiglioni, Alberto Marchesi +2

We study a repeated information design problem faced by an informed sender who tries to influence the behavior of a self-interested receiver. We consider settings where the receive…
