New CoCo loss function enhances embedding structure and convergence

Researchers have developed a new loss function called CoCo, designed to create normalized and well-structured data representations. CoCo encourages classes to collapse internally while contrasting with other classes, aiming for embeddings with large angular separation. Theoretical analysis suggests CoCo offers advantages over objectives like dot regression and cross-entropy, including better initialization, more informative gradients, and faster convergence. Experiments on the OpenML-CC18 benchmark demonstrated that CoCo performs competitively with existing methods like kernel SVM and random forest, while promoting tighter class clustering and improved predictive performance.

    Contrastive-Collapsed Loss for Flexible and Geometrically Optimal Embeddings and Faster Convergence

    In this work, we introduce CoCo, a loss function aimed at learning normalized and well-structured representations. The proposed loss encourages intra-class collapse and inter-class contrast while preserving sufficient flexibility for neural networks to approximate geometrically o…
