Figure Lengend Snippet: Grad-CAM visualization for ResNet101 applied to six ultrasound images (three benign and three malignant). The figure is structured in a 3 × 6 format, where the first column contains benign images, the second column shows the corresponding Grad-CAM results from the original network, and the third column presents the Grad-CAM results from the True network. Similarly, the fourth column contains malignant images, followed by Grad-CAM results from the original network in the fifth column and those from the True network in the sixth column. The color scale from red to blue represents the importance of different image regions, where red indicates the most critical areas used for classification. The selected images include cases where the original network misclassified or had a small probability difference, whereas the True network provided correct classification with a higher probability difference.
