JEPA Policy: Diffusion-Free Imitation Learning via Paired Action and Future Representation Prediction

[Paper Quick Read] Robots Learn Actions and 'Future States' Simultaneously: High-Speed Imitation Learning with JEPA Policy

Summary

JEPA Policy improves imitation learning by predicting both action chunks and future state representations simultaneously within a single Transformer. It achieves an average success rate of 83.0% across nine simulation tasks, up from 77.4%, with minimal latency increase. The method avoids generating detailed future videos, instead focusing on latent representations that capture task-relevant outcomes.

Editorial context

The paper introduces JEPA Policy, a method for imitation learning that jointly predicts action chunks and future state representations, achieving a 5.6 percentage point improvement in success rate across nine simulation tasks without using diffusion models.

of success rates across 9 robot tasks For simulation evaluation, we used MokaMoka, MugMug, Square, Tool Hang, Transport, Coffee Preparation, Kitchen, Three Piece Assembly, and Hammer Cleanup. JEPA Policy outperformed action-only MIP in all 9 tasks, with the average improving by 5.6 points from 77.4% to 83.0%. The largest improvements were in Coffee Preparation, from 57.5% to 77.5%, and Tool Hang, from 65.8% to 75.0%.

It also outperformed the Diffusion Policy's 9-task average of 75.1%. Gains of 4.7 to 5.3 points remained not only for the best checkpoint but also for the average of all 30 evaluations and the average of the last 5 evaluations. The pooled ranking was the same for 5 physical robot tasks totaling 630 episodes. However, the number of tasks and seeds was limited, so these results do not guarantee generalization to all r
