Sequential Decision-Making Under Uncertainty Using Hybrid Probability-Possibility Functions

Collective Multiagent Sequential Decision Making Under Uncertainty

Multiagent sequential decision making has seen rapid progress with formal models such as decentralized MDPs and POMDPs. However, scalability to large multiagent systems and applicability to real world problems remain limited. To address these challenges, we study multiagent planning problems where the collective behavior of a population of agents affects the joint-reward and environment dynamic...

Rank-Dependent Probability Weighting in Sequential Decision Problems under Uncertainty

This paper is devoted to the computation of optimal strategies in automated sequential decision problems. We consider here problems where one seeks a strategy which is optimal for rank dependent utility (RDU). RDU generalizes von Neumann and Morgenstern’s expected utility (by probability weighting) to encompass rational decision behaviors that EU cannot accomodate. The induced algorithmic probl...

Sequential decision making in repeated coalition formation under uncertainty

The problem of coalition formation when agents are uncertain about the types or capabilities of their potential partners is a critical one. In [3] a Bayesian reinforcement learning framework is developed for this problem when coalitions are formed (and tasks undertaken) repeatedly: not only does the model allow agents to refine their beliefs about the types of others, but uses value of informat...

POMDPs.jl: A Framework for Sequential Decision Making under Uncertainty

POMDPs.jl is an open-source framework for solving Markov decision processes (MDPs) and partially observable MDPs (POMDPs). POMDPs.jl allows users to specify sequential decision making problems with minimal effort without sacrificing the expressive nature of POMDPs, making this framework viable for both educational and research purposes. It is written in the Julia language to allow flexible prot...
