Do No Harm: A Counterfactual Approach to Safe Reinforcement Learning

no code implementations19 May 2024 Sean Vaskov, Wilko Schwarting, Chris L. Baker

In such methods, if agents are initialized in, or must visit, states where constraint violation might be inevitable, it is unclear how much they should be penalized.

Friction

Friction-Adaptive Stochastic Nonlinear Model Predictive Control for Autonomous Vehicles

no code implementations5 May 2023 Sean Vaskov, Rien Quirynen, Marcel Menner, Karl Berntorp

The estimators output the estimate of the tire-friction model as well as the uncertainty of the estimate, which expresses the confidence in the model for different driving regimes.

Guaranteed Safe Reachability-based Trajectory Design for a High-Fidelity Model of an Autonomous Passenger Vehicle

1 code implementation5 Feb 2019 Sean Vaskov, Utkarsh Sharma, Shreyas Kousik, Matthew Johnson-Roberson, Ramanarayan Vasudevan

Trajectory planning is challenging for autonomous cars since they operate in unpredictable environments with limited sensor horizons.

Bridging the Gap Between Safety and Real-Time Performance in Receding-Horizon Trajectory Design for Mobile Robots

1 code implementation18 Sep 2018 Shreyas Kousik, Sean Vaskov, Fan Bu, Matthew Johnson-Roberson, Ram Vasudevan

At runtime, the FRS is used to map obstacles to the space of parameterized trajectories, which allows RTD to select a safe trajectory at every planning iteration.

Safe Trajectory Synthesis for Autonomous Driving in Unforeseen Environments

2 code implementations28 Apr 2017 Shreyas Kousik, Sean Vaskov, Matthew Johnson-Roberson, Ramanarayan Vasudevan

Path planning for autonomous vehicles in arbitrary environments requires a guarantee of safety, but this can be impractical to ensure in real-time when the vehicle is described with a high-fidelity model.
