Researchers have found that geographic diversity in training data is more crucial than sheer volume for improving the cross-domain generalization of self-supervised latent world models used in autonomous driving. A study training JEPA-based models on data from Pittsburgh, Boston, and Singapore demonstrated significantly better performance on unseen scenarios in Miami and Austin compared to models trained on an equal amount of data from a single region. Even training on a larger dataset from just one geography did not match the generalization capabilities of the geographically diverse, smaller dataset, highlighting the importance of varied environments for robust model performance.
