Hierarchical Imitation Learning for Stochastic Environments

IROS 2023poster

Many applications of imitation learning require the agent to generate the full distribution of behaviour observed in the training data. For example, to evaluate the safety of autonomous vehicles in simulation, accurate and diverse behaviour models of other road users are paramount. Existing methods…

Embedding Synthetic Off-Policy Experience for Autonomous Driving via Zero-Shot Curricula

CoRL 2022oral

ML-based motion planning is a promising approach to produce agents that exhibit complex behaviors, and automatically adapt to novel environments. In the context of autonomous driving, it is common to treat all available training data equally. However, this approach produces agents that do not perfor…

Posetal Games: Efficiency, Existence, and Refinement of Equilibria in Games With Prioritized Metrics

RA-L 2022

Modern applications require robots to comply with multiple, often conflicting rules and to interact with the other agents. We present Posetal Games as a class of games in which each player expresses a preference over the outcomes via a partially ordered set of metrics. This allows one to combine hie

A Holistic Motion Planning and Control Solution to Challenge a Professional Racecar Driver

RA-L 2021

We present a holistically designed three layer control architecture capable of outperforming a professional driver racing the same car. Our approach focuses on the co-design of the motion planning and control layers, extracting the full potential of the connected system. First, a high-level planner

End-to-End Velocity Estimation for Autonomous Racing

RA-L 2020

Velocity estimation plays a central role in driverless vehicles, but standard, and affordable methods struggle to cope with extreme scenarios like aggressive maneuvers due to the presence of high sideslip. To solve this, autonomous race cars are usually equipped with expensive external velocity sens
