SAILOR is an inverse RL algorithm that learns world and reward models to search at test-time and recover from mistakes.

Active Imitation Learing with Noisy Guidance

Integrating π₀-Droid into SAILOR for robust robotic imitation learning, combining pretrained vision-language-action priors with recovery-based search on RoboMimic.
