Data-Efficient Adaptation of a Driving VLA to Class 8 Trucks
Satyajeet Das, Aaron Buxbaum, Niels Joubert +1
Class 8 trucks differ from passenger cars in geometry, dynamics, and maneuvering requirements. As a result, vision-language-action (VLA) models trained for passenger vehicles do no…

Steering Multirobot Behavior via Closed-Loop Affine Activation Editing
Satyajeet Das, Darren Chiu, Shashank Hegde +1
Real-world robots need to adapt their behavior beyond the envelope of their pre-trained policy. Policy finetuning or retraining are options, but they risk catastrophic forgetting,…

Latent Activation Editing: Inference-Time Refinement of Learned Policies for Safer Multirobot Navigation
Satyajeet Das, Darren Chiu, Zhehui Huang +2
Reinforcement learning has enabled significant progress in complex domains such as coordinating and navigating multiple quadrotors. However, even well-trained policies remain vulne…
