JEPA-Anything: Learning Predictive Models across Different Worlds

Summary

JEPA-Anything: Learning Predictive Models across Different Worlds 摘要 World modeling enables intelligence to anticipate consequences, guide interventions, and learn from interaction. Yet predictive models remain domain-specific: can a common learning principle support world modeling across radically different systems? We introduce JEPA-Anything, a domain-agnostic framework based on orthogonal predictive factorization (OPF). Extending joint-embedding predictive architectures, OPF decomposes latent targets into complementary factors, learns them through dedicated pathways, and recombines them within a shared predictive design. We evaluate JEPA-Anything across seven domains: vision, biology, clinical trajectories, control, molecular dynamics, physical fields, and weather. Experiments span representation learning, intervention prediction, out-of-distribution generalization, and long-horizon dynamics, including 10 matched dynamics tasks, forecasting of over 1,000 clinical events, and 100-step molecular rollouts across four systems. Against matched JEPA baselines, JEPA-Anything improves reported metrics on all 10 dynamics tasks and reduces single-intervention prediction error on Interventional Pong by 34.8%. It achieves the lowest one-step and 100-step molecular errors among compared methods in all four systems. Beyond prediction, a factor-nominated biological intervention receives experimental support in cell co-cultures, patient-derived organoids, tumor fragments, and mice; latent orbital modes recover the Keplerian scaling exponent with a fitted slope of −1.4991. These results support a common factorized predictive principle across heterogeneous worlds, connecting world modeling with intervention and experimentally grounded scientific discovery. 作者 期刊/会议 引用 BibTeX @article{cui2026jepa, title={JEPA-Anything: Learning Predictive Models across Different Worlds}, author={Cui, Taoyong and Wang, Zhongyao and Xu, Xinyue and Liu, Weiyang and Yu, Zhaochen and Zhang, Yuying and Gao, Qiang and Yang, Mengyue and Ouyang, Wanli and Heng, Pheng Ann and Wu, Yingcheng and Yin, Zhenfei and Yang, Ling}, journal={arXiv preprint arXiv:2609.20800}, year={2026} }
