More for Less: Safe Policy Improvement With Stronger Performance Guarantees

1 code implementation13 May 2023 Patrick Wienhöft, Marnix Suilen, Thiago D. Simão, Clemens Dubslaff, Christel Baier, Nils Jansen

In an offline reinforcement learning setting, the safe policy improvement (SPI) problem aims to improve the performance of a behavior policy according to which sample data has been generated.

Decision-Making Under Uncertainty: Beyond Probabilities

no code implementations10 Mar 2023 Thom Badings, Thiago D. Simão, Marnix Suilen, Nils Jansen

In this paper, the focus is on the uncertainty that goes beyond this classical interpretation, particularly by employing a clear distinction between aleatoric and epistemic uncertainty.

Safe Policy Improvement for POMDPs via Finite-State Controllers

no code implementations12 Jan 2023 Thiago D. Simão, Marnix Suilen, Nils Jansen

In our novel approach to the SPI problem for POMDPs, we assume that a finite-state controller (FSC) represents the behavior policy and that finite memory is sufficient to derive optimal policies.

Robust Anytime Learning of Markov Decision Processes

1 code implementation31 May 2022 Marnix Suilen, Thiago D. Simão, David Parker, Nils Jansen

Markov decision processes (MDPs) are formal models commonly used in sequential decision-making.

Robust Finite-State Controllers for Uncertain POMDPs

no code implementations24 Sep 2020 Murat Cubuktepe, Nils Jansen, Sebastian Junges, Ahmadreza Marandi, Marnix Suilen, Ufuk Topcu

(3) We linearize this dual problem and (4) solve the resulting finite linear program to obtain locally optimal solutions to the original problem.
