HEAT, ATELECTASIS, RETRACTION POCKET
The heat map of the CAM image was generated using otoscopic images from the validation set. The CAM showed that the DL model was capable of identifying attic retraction pocket accurately with the color red, with deeper or larger cases of attic retraction pocket possessing more values (Fig. Receiver–operator characteristic (ROC) curves and corresponding area under the ROC curve (AUC) of the deep learning model for the detection of atelectasisClass activation maps of the deep learning model for the detection of atelectasis.

The red-colored area represents the discriminative region in the otoscopic images, whereas the blue-colored area represents a non-specific region in the otoscopic images.
