Sub-JEPA: a simple fix to LeCun group's LeWorldModel that consistently improves performance [P]

In three linesSub-JEPA improves LeWorldModel (LeCun's group, NYU) by applying Gaussian regularization within frozen random orthogonal subspaces instead of globally. Gains up to +10.7 pp on Two-Room, straighter latent trajectories, better physical state decodability. Code and paper released.
