SAGE: Subgoal-Conditioned Action Generation for Latent World Model Planning

Experiments show that coupling latent subgoal decomposition with prior-conditioned action generation substantially improves long-horizon planning while preserving strong short-horizon performance.

Mitigating Compounding Error via Video Representation Regularization

This work establishes the first connection between autoregressive video drifting and model internal representations, adopts erank as a quantitative metric for error accumulation, reveals counterintuitive scaling limitations for video world models, and presents a simple yet effective regularization strategy to improve l...

DWM: Separating World Effects from Actions in Latent World Models

DWM (Decomposed World Model), a supervision-level framework that operationalizes an explicit additive decomposition of the predicted transition into an action-invariant and a complementary action-driven component, without altering the underlying architecture or inference pipeline.
