Hierarchy-Aware Cross-Entropy improves image classification accuracy

Researchers have introduced Hierarchy-Aware Cross-Entropy (HACE), a novel loss function designed to improve image classification by accounting for semantic relationships between classes. Unlike standard cross-entropy, HACE incorporates a class hierarchy to better handle misclassifications. The method involves aggregating prediction probabilities upward and applying ancestral label smoothing to the ground truth. Evaluations on datasets like CIFAR-100 demonstrated that HACE can enhance accuracy, particularly when used with frozen DINOv2-Large features. AI

    When Labels Have Structure: Improving Image Classification with Hierarchy-Aware Cross-Entropy

    arXiv:2605.06274v1 Announce Type: new Abstract: Standard cross-entropy is the default classification loss across virtually all of machine learning, yet it treats all misclassifications equally, ignoring the semantic distances that a class hierarchy encodes. We propose Hierarchy-A…
