Sub-JEPA improves world models by relaxing global Gaussian constraints
Researchers propose Sub-JEPA, a modification to NYU's LeWorldModel that applies Gaussian regularization within random subspaces instead of globally, yielding up to 10.7 percentage point gains on low-dimensional tasks.

A team of researchers has identified and fixed a fundamental mismatch in how LeWorldModel, NYU's recent approach to joint-embedding predictive architecture (JEPA), constrains latent representations during world model training. The fix, called Sub-JEPA, applies the same regularization objective but w...
