Residual-MPPI: Online Policy Customization for Continuous Control

ICLR 2025poster

Policies developed through Reinforcement Learning (RL) and Imitation Learning (IL) have shown great potential in continuous control tasks, but real-world applications often require adapting trained policies to unforeseen requirements. While fine-tuning can address such needs, it typically requires a…

BeTAIL: Behavior Transformer Adversarial Imitation Learning From Human Racing Gameplay

RA-L 2024

Autonomous racing poses a significant challenge for control, requiring planning minimum-time trajectories under uncertain dynamics and controlling vehicles at their handling limits. Current methods requiring hand-designed physical models or reward functions specific to each car or track. In contrast

Skill-Critic: Refining Learned Skills for Hierarchical Reinforcement Learning

RA-L 2024

Hierarchical reinforcement learning (RL) can accelerate long-horizon decision-making by temporally abstracting a policy into multiple levels. Promising results in sparse reward environments have been seen with <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999
