A Joint-Embedding Predictive Architecture (JEPA) world model trained from scratch on Super Mario Bros, called LeMario, achieves strong short-horizon prediction and short-range visual goal seeking but …
Hi-LeWM, an extension of LeWorldModel (LeWM) that integrates high-level planning over latent subgoals while keeping the low-level LeWM frozen, outperformed its predecessor by 11.3 percentage points at…
A developer trained a Joint-Embedding Predictive Architecture (JEPA) world model, called LeMario, on Super Mario Bros from scratch, finding the model could predict five-step futures and perform reward…
Researchers propose Fast LeWorldModel (Fast-LeWM), a fast latent world model that replaces repeated local rollout with action-prefix prediction, improving average success over LeWM while substantially…
