large behavior model

Definition of large behavior model

1. : a large, general-purpose model trained across many robot demonstrations or action trajectories to generate behavior for multiple physical tasks rather than controlling only one narrowly programmed skill

   • The humanoid's large behavior model coordinated walking, lifting, and packing through one learned policy.
   • Engineers added a new manipulation skill to the LBM by collecting demonstrations instead of writing a separate controller from scratch.

2. : a foundation-scale model trained on chronological records of human or user actions to represent behavioral patterns and predict what action may happen next, often with a probability or time window

   • The retailer used a large behavioral model to estimate which customers were likely to visit after a promotion.
   • A behavioral prediction is probabilistic, so the LBM's output should not be treated as a fixed description of a person.
