Frozen in a Frame: The Velocity Blind Spot in JEPA World Models
Tinghe Zhang, Chunyu Liu, Yu Leon Liu +6
Joint-embedding predictive architectures (JEPAs) for world modeling train an encoder so a predictor maps a current embedding and action to the next frame's embedding, always from a…

A Unified Framework for Trajectory Prediction with Explicit Planning and Reaction Decomposition
Jiaheng Chen, Jiaxing Li, Tinghe Zhang +1
Trajectory prediction has shifted toward structured formulations with explicit social modeling. However, existing methods inadequately distinguish the functional roles of social in…

NodeJEPA: Structure-Conditioned Latent Prediction for Node-Level Graph Self-Supervised Learning
Tinghe Zhang, Jian Xu, Jiaheng Chen +3
Self-supervised learning on graphs is largely shaped by contrastive methods that depend on carefully designed augmentations, and by generative methods that reconstruct node attribu…
