New loss function improves AI set-valued classifiers on imbalanced data

Researchers have developed a modified version of the odd-K-out (OKO) loss function to improve the performance of set-valued classifiers on imbalanced datasets. This adapted OKO loss function enhances sample efficiency and reduces computational overhead compared to standard cross-entropy training. Experiments show that this approach significantly boosts macro-accuracy for minority classes across various set-valued classification methods, without substantially increasing prediction set sizes.
