Researchers Taewook Kang, Taeheon Kim, Donghyun Shin, and Jonghyun Choi propose DART (Domain ARiThmetic), a method enabling Vision-Language-Action models to adapt to environmental shifts using only a single demonstration per task.
DART employs weight vector arithmetic combined with domain-specific information addition and subspace alignment to filter noise, outperforming existing VLA adaptation methods in one-shot learning scenarios.
The method handles environmental changes including camera pose shifts and transitions between similar robots (e.g., Panda to UR5e), validated in both simulated and real-world experiments with publicly available code.
