Safety Aware Autonomous Path Planning Using Model Predictive Reinforcement Learning for Inland Waterways

no code implementations16 Nov 2023 Astrid Vanneste, Simon Vanneste, Olivier Vasseur, Robin Janssens, Mattias Billast, Ali Anwar, Kevin Mets, Tom De Schepper, Siegfried Mercelis, Peter Hellinckx

We demonstrate our approach on two scenarios and compare the resulting path with path planning using a Frenet frame and path planning based on a proximal policy optimization (PPO) agent.

Improved inter-scanner MS lesion segmentation by adversarial training on longitudinal data

no code implementations3 Feb 2020 Mattias Billast, Maria Ines Meyer, Diana M. Sima, David Robben

A discriminator model is then trained to predict if two lesion segmentations are based on scans acquired using the same scanner type or not, achieving a 78% accuracy in this task.
