Waymo's simulator is a large AI model for closed-loop evaluation and training.
Waymo's simulator is a large AI model for closed-loop evaluation and training.
Dmitri Dolgov says a real simulator is itself a large AI model, and Waymo has built behavioral and sensing world models to support closed-loop evaluation and training.
