New CoCo loss function enhances embedding quality and speeds up convergence

Researchers have introduced CoCo, a novel loss function designed to enhance the learning of normalized and structured representations in machine learning models. This new objective encourages intra-class collapse and inter-class contrast, aiming to create embeddings with significant angular separation between classes. Theoretical analysis and experiments on the OpenML-CC18 benchmark indicate that CoCo offers advantages over existing methods like cross-entropy and kernel SVMs, promoting tighter class clustering and faster convergence.
