Graph Neural Networks and Reinforcement Learning for Behavior Generation in Semantic Environments

2 code implementations22 Jun 2020 Patrick Hart, Alois Knoll

We show that graph neural networks are capable of handling scenarios with a varying number and order of vehicles during training and application.

Counterfactual Policy Evaluation for Decision-Making in Autonomous Driving

2 code implementations20 Mar 2020 Patrick Hart, Alois Knoll

If a policy can handle all counterfactual worlds well, it either has seen similar situations during training or it generalizes well and is deemed to be fit enough to be executed in the actual world.

Lane-Merging Using Policy-based Reinforcement Learning and Post-Optimization

no code implementations6 Mar 2020 Patrick Hart, Leonard Rychly, Alois Knol

By storing the state-history during reinforcement learning, it can be used for constraint checking and the optimizer can account for interactions.

BARK: Open Behavior Benchmarking in Multi-Agent Environments

3 code implementations5 Mar 2020 Julian Bernhard, Klemens Esterle, Patrick Hart, Tobias Kessler

As driving tests are costly and challenging scenarios are hard to find and reproduce, simulation is widely used to develop, test, and benchmark behavior models.
