Researchers have developed COJEPA, a new self-supervised learning framework for brain MRI scans. This method combines a joint-embedding predictive architecture with a contrastive loss to enhance representations by focusing on both local predictivity and global discriminability. Trained on over 2,000 structural MRI scans, COJEPA demonstrated strong performance in zero-shot twin retrieval, brain tumor segmentation, and age regression tasks, outperforming existing methods in several evaluations.
