New loss function tackles 'center-class hedging' in ordinal classification

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new loss function called Adaptive Margin Ordinal Loss (AMOL) to address a specific failure mode in ordinal classification tasks, known as center-class hedging. This phenomenon causes neural networks to favor predictions towards the middle classes, irrespective of the true label, by minimizing symmetric loss. AMOL applies a multiplicative weight that is large when the predicted class is near the center and the true label is far from it, thereby penalizing this hedging behavior. An asymmetric variant, AMOL-asym, was shown to completely eliminate center-class hedging on the Abalone dataset. AI

IMPACT Introduces a method to improve accuracy in ordinal classification tasks by directly addressing prediction bias towards central classes.

    Adaptive Margin Ordinal Loss: Penalizing Center-Class Hedging in Ordinal Classification

    arXiv:2609.10752v1 Announce Type: new Abstract: Standard cross-entropy loss causes neural networks trained on ordinal classification tasks to hedge predictions toward center classes, a failure mode we term \emph{center-class hedging}. This occurs because predicting the middle cla…
