Egocentric human data is abundant, but human motion is not always positive supervision for robot policy due to embodiment gaps. Naive BC co-training can HURT performance โน๏ธ.
๐Our key finding in **EgoWAM**: the state-prediction branch of a World Action Model effectively bridges this embodiment gap, enabling robot performance to scale with diverse **in-the-wild** human data.
๐กThe key question then becomes: what world representation transfers best across embodiments?
๐๐ปLetโs take a deep dive into it:
