Robust optimization for adversarial learning with finite sample complexity guarantees

no code implementations22 Mar 2024 André Bertolace, Konstatinos Gatsis, Kostas Margellos

Decision making and learning in the presence of uncertainty has attracted significant attention in view of the increasing need to achieve robust and reliable operations.

Decision Making

Learning Robust Policies for Uncertain Parametric Markov Decision Processes

no code implementations11 Dec 2023 Luke Rickard, Alessandro Abate, Kostas Margellos

Synthesising verifiably correct controllers for dynamical systems is crucial for safety-critical problems.

Multi-objective low-thrust spacecraft trajectory design using reachability analysis

no code implementations14 Dec 2022 Nikolaus Vertovec, Sina Ober-Blöbaum, Kostas Margellos

One of the fundamental problems in spacecraft trajectory design is finding the optimal transfer trajectory that minimizes the propellant consumption and transfer time simultaneously.

Tracking-based distributed equilibrium seeking for aggregative games

no code implementations26 Oct 2022 Guido Carnevale, Filippo Fabiani, Filiberto Fele, Kostas Margellos, Giuseppe Notarstefano

We propose fully-distributed algorithms for Nash equilibrium seeking in aggregative games over networks.

Safety-Aware Optimal Control for Motion Planning with Low Computing Complexity

no code implementations28 Apr 2022 Xuda Ding, Han Wang, Jianping He, Cailian Chen, Kostas Margellos, Antonis Papachristodoulou

Simulations demonstrates that BRSCA has a higher probability of finding feasible solutions, reduces the computation time by about 17. 4% and the energy cost by about four times compared to other methods in the literature.

Motion Planning

Verification of safety critical control policies using kernel methods

no code implementations23 Mar 2022 Nikolaus Vertovec, Sina Ober-Blöbaum, Kostas Margellos

Hamilton-Jacobi reachability methods for safety-critical control have been well studied, but the safety guarantees derived rely on the accuracy of the numerical computation.

Probabilistic stabilizability certificates for a class of black-box linear systems

no code implementations4 Mar 2021 Filippo Fabiani, Kostas Margellos, Paul J. Goulart

We provide out-of-sample certificates on the controlled invariance property of a given set with respect to a class of black-box linear systems.
