RecBayes: Recurrent Bayesian Ad Hoc Teamwork in Large Partially Observable Domains

João G. Ribeiro, Yaniv Oren, Alberto Sardinha +2

This paper proposes RecBayes, a novel approach for ad hoc teamwork under partial observability, a setting where agents are deployed on-the-fly to environments where pre-existing te…

Solving General-Utility Markov Decision Processes in the Single-Trial Regime with Online Planning

Pedro P. Santos, Alberto Sardinha, Francisco S. Melo

In this work, we contribute the first approach to solve infinite-horizon discounted general-utility Markov decision processes (GUMDPs) in the single-trial regime, i.e., when the ag…

Implicit Repair with Reinforcement Learning in Emergent Communication

Fábio Vital, Alberto Sardinha, Francisco S. Melo

Conversational repair is a mechanism used to detect and resolve miscommunication and misinformation problems when two or more agents interact. One particular and underexplored form…

Distributed Value Decomposition Networks with Networked Agents

Guilherme S. Varela, Alberto Sardinha, Francisco S. Melo

We investigate the problem of distributed training under partial observability, whereby cooperative multi-agent reinforcement learning agents (MARL) maximize the expected cumulativ…

Networked Agents in the Dark: Team Value Learning under Partial Observability

Guilherme S. Varela, Alberto Sardinha, Francisco S. Melo

We propose a novel cooperative multi-agent reinforcement learning (MARL) approach for networked agents. In contrast to previous methods that rely on complete state information or j…
