SELFI is an online reinforcement learning approach for fine-tuning control policies trained with
model-based learning. We combine the objective used during model-based learning with a Q-value function
learned online.
NoMaD is a novel architecture for robotic navigation in previously unseen environments that uses a unified diffusion policy to jointly represent exploratory task-agnostic behavior and goal-directed task-specific behavior.
GNM is vision-based navigation policy trained with a simple goal-reaching objective on a cross-embodiment navigation dataset.
It exhibits positive transfer, outperforming specialist models trained on singular embodiment datasets, and generalizes to new robots.
ExAug is a vision-based navigation policy that learns to control robots with varying camera types, camera placements, robot sizes, and velocity constraints by applying a novel geometric-aware objective to view augmented data.
