A new research paper explores what physical quantities latent world models can learn by using a controlled environment called POKEWORLD. The study found that the model's ability to identify physical parameters like mass, drag, and stiffness depends on both the input data and the prediction targets. Specifically, stiffness is only internalized when touch is predicted, and drag is poorly retained even with ample data unless specific prediction objectives are used. The research suggests that the structure of the objective function, rather than just the amount of data, determines which physical parameters a latent representation acquires. AI
