Understanding the limits of latent world models
None of the latent world models studied solved its task by faithfully modeling the environment’s dynamics, the authors report.
The paper distinguishes task performance from whether a model’s internal predictions reflect the environment’s underlying structure. It defines faithfulness as a mathematical correspondence between environmental transitions and learned latent dynamics. The authors propose latent rollout consistency (LRC) to evaluate predictions conditioned on actions. Their finding applies to the state-of-the-art models examined in the study.
