UR-JEPA: Uniform Rectifiability as a Regularizer for Joint-Embedding Predictive Architectures
Researchers have introduced UR-JEPA, a novel method for training Joint-Embedding Predictive Architectures (JEPAs). This new approach aims to prevent representation collapse by enforcing uniform rectifiability, a geometric property, on embeddings. UR-JEPA demonstrates improved performance and reduced variance compared to existing methods like LeJEPA, particularly on smaller datasets and with limited seeds, while producing distinct projected representations.
