From Implicit Latents to Explicit Physics: Retained Decoding with Budgeted Supervision in LeWorldModel

Joint-Embedding Predictive Architectures (JEPA) train world models to imagine action consequences in latent space, but the physical quantities they encode remain implicit and unreadable from the outside. We extend LeWorldModel (LeWM) with a shared decoder head on its latent, reta...
