Truly No-Regret Learning in Constrained MDPs

no code implementations24 Feb 2024 Adrian Müller, Pragnya Alatur, Volkan Cevher, Giorgia Ramponi, Niao He

As Efroni et al. (2020) pointed out, it is an open question whether primal-dual algorithms can provably achieve sublinear regret if we do not allow error cancellations.

Provably Learning Nash Policies in Constrained Markov Potential Games

no code implementations13 Jun 2023 Pragnya Alatur, Giorgia Ramponi, Niao He, Andreas Krause

Multi-agent reinforcement learning (MARL) addresses sequential decision-making problems with multiple agents, where each agent optimizes its own objective.

Cancellation-Free Regret Bounds for Lagrangian Approaches in Constrained Markov Decision Processes

no code implementations12 Jun 2023 Adrian Müller, Pragnya Alatur, Giorgia Ramponi, Niao He

Unlike existing Lagrangian approaches, our algorithm achieves this regret without the need for the cancellation of errors.

Multi-Player Bandits: The Adversarial Case

no code implementations21 Feb 2019 Pragnya Alatur, Kfir. Y. Levy, Andreas Krause

We consider a setting where multiple players sequentially choose among a common set of actions (arms).
