One interaction can teach a robot hidden physics

What changedT2-Z adds an environment latent that is optimized from one or more interactions while the trained robotic world model stays frozen. Reported prediction error fell from 15.20 to 7.00 and action success rose from 33.73 to 72.96 percent; some settings adapted from one trajectory.

Real and simulated robot scenes illustrate adaptation to hidden environmental properties.
