Fig. 4From: Preliminary analysis of predicting the first recurrence in patients with neovascular age-related macular degeneration using deep learningRepresentative cases of gradient-weighted class activation mapping (Grad-CAM) visualization. Grad-CAM extracts the feature map of the last convolutional layer and shows a heatmap within the image describing the calculated weight of the feature map.
