Fig. 7: Incorrect prediction samples for the proposed HPDT model and comparison with two other hierarchical models.
From: Hierarchical skin lesion image classification with prototypical decision tree
a A benign melanocytic blue lesion is misclassified as benign melanocytic nevus by HPDT (red path), with DHC and CNN-Transformer succeeding at Levels 1–2 but failing at Level 3. b A benign keratinocytic solar lentigo is misclassified as benign keratinocytic nevus by HPDT, while DHC and CNN-Transformer fail at Level 2 and show inconsistent predictions between Level 2 and 3 (green checkmarks indicate correct predictions, red crosses indicate incorrect predictions, and yellow exclamation marks indicate inconsistent predictions).
