What Can Latent World Models Know? Physical Parameter Identifiability in Multimodal Predictive Representations

Kaizhen Tan et al. · arXiv:2607.27017v3 Announce Type: replace-cross Abstract: A central premise of latent world models is that predicting the future forces a representation to internalize the physics of its environment. Which physical quantities does a trained latent actually contain, and what decides this? We answer with controlled interventions in POKEWORLD, an interactive environment whose visually identical objects hide mass, drag, and contact stiffness. A certificate-gated protocol first certifies each paramet
