  • To solve this, each video prediction is conditioned on the action being executed currently, ensuring a continuous trajectory.

  • Model inference takes time, but the physical world does not wait for the model to decide. Therefore, we overlap inference and action execution to ensure continuous control, as depicted in Figure 3. Each video prediction is long enough to cover the next prediction's latency.

  • Translating Video to Action with Inverse Dynamics Models The second main component of our system is an inverse dynamics model, which performs video-to-action translation: given a predicted video, it produces the precise robot motor signals needed to re-enact the depicted actions. Causal action prediction — as in a typical robot policy — predicts future actions conditioned on the past and thus requires modeling behavior and decision-making. Behavior may be arbitrarily complex, and for generalist behavior, may require a data scale infeasible to collect on robots. In contrast, non-causal video-to…

  • All of that data suggests increasing concentration. Through this lens, the SaaSpocalypse (the violent sell-off in software stocks) is less about software writ large dying, and more about point solution software finally facing economic gravity. They are no longer getting a free pass simply for having a good business model.
