arXiv:2606.31232v1 Announce Type: new Abstract: Learning visual world models for planning requires compact latent dynamics that remain sensitive to actions, yet reconstruction-free joint-embedding objectives can collapse to action-insensitive representations. We propose Delta-JEPA, an end-to-end reconstruction-free world model that augments latent forward prediction with a Latent Difference Action Decoder (LDAD). Unlike inverse decoders that infer actions from concatenated endpoint embeddings, LDAD reconstructs the executed action from the latent displacement between consecutive observations.
This development arises from ongoing research into making AI models more robust and action-sensitive for complex tasks like robotic planning, pushing boundaries in world model learning.
Improving action sensitivity in latent world models is crucial for effective autonomous systems, directly enabling more capable AI agents and better robotic control.
The proposed Delta-JEPA model offers a novel, reconstruction-free approach to learning action-sensitive representations, potentially accelerating progress in goal-directed planning and advanced AI autonomy.
