Causal Video Models Are Data-Efficient Robot Policy Learners

Rhoda AI proposes Direct Video-Action Model (DVA), reformulating robot control as video generation to leverage web-scale video pre-training. It achieves data-efficient task learning, long-context memory, one-shot learning, and interpretability. With only ~10 hours of robot data, it performs complex long-horizon tasks and can learn from a single demonstration in context.

Key points

  • DVA reformulates robot policy as video generation, enabling data-efficient learning from web-scale video pre-training.
  • The model natively handles hundreds of frames of visual context for complex multi-step tasks.
  • An inverse dynamics model requires only ~10 hours of data to accurately translate video to actions.
  • Context Amortization and Leapfrog Inference strategies enable efficient training and real-time closed-loop control.
