Strengthening Deterministic Policies for POMDPs

no code implementations16 Jul 2020 Leonore Winterer, Ralf Wimmer, Nils Jansen, Bernd Becker

Second, based on the results of the original MILP, we employ a preprocessing of the POMDP to encompass memory-based decisions.

Counterexample-Guided Strategy Improvement for POMDPs Using Recurrent Neural Networks

no code implementations20 Mar 2019 Steven Carr, Nils Jansen, Ralf Wimmer, Alexandru C. Serban, Bernd Becker, Ufuk Topcu

The particular problem is to determine strategies that provably adhere to (probabilistic) temporal logic constraints.

Human-in-the-Loop Synthesis for Partially Observable Markov Decision Processes

no code implementations27 Feb 2018 Steven Carr, Nils Jansen, Ralf Wimmer, Jie Fu, Ufuk Topcu

The efficient verification of this MC gives quantitative insights into the quality of the inferred human strategy by proving or disproving given system specifications.

Strategy Synthesis in POMDPs via Game-Based Abstractions

no code implementations14 Aug 2017 Leonore Winterer, Sebastian Junges, Ralf Wimmer, Nils Jansen, Ufuk Topcu, Joost-Pieter Katoen, Bernd Becker

We study synthesis problems with constraints in partially observable Markov decision processes (POMDPs), where the objective is to compute a strategy for an agent that is guaranteed to satisfy certain safety and performance specifications.
