Geographic Diversity Beats Data Volume for Cross-Domain Generalization in Zero-Label JEPA Driving World Models

arXiv 2026 27.1 application

TLDR

Geographic diversity in training data improves cross-domain generalization of JEPA driving world models more than increasing data volume.

Reasoning

The paper presents a clear controlled experiment with quantitative results showing that diverse geographic data reduces surprise scores significantly compared to single-geography data, even when the latter has 3x more data. Strengths include rigorous ablation and real-world datasets; weaknesses are the narrow domain and lack of comparison to other model types.
