Researchers have introduced Minimax Generalized Cross-Entropy (MGCE), a novel loss function designed to improve supervised classification performance. Unlike previous formulations of GCE that suffered from non-convex optimization and underfitting, MGCE offers a convex optimization approach. This new method demonstrates faster convergence, better calibration, and strong accuracy, particularly when dealing with noisy labels, by providing an upper bound on classification error. AI
