Researchers have developed a new method for training world models, particularly those based on the Joint Embedding Predictive Architecture (JEPA), to improve their ability to learn from complex real-world robot data. By incorporating depth as a geometric prior during training, combined with a SIGReg regularizer that promotes latent diversity while organizing it according to scene geometry, the models achieve more transferable representations. An 18M-parameter model trained with this approach demonstrated a 33% reduction in visual odometry probe error and significantly improved surprise detection and rollout fidelity on benchmarks like TartanGround, even showing gains in understanding physics-related concepts not directly tied to 3D geometry.
