Fig 4. Receiver operating characteristic curve of the AI for binary classification.

The receiver operating characteristic (ROC) curve of AI for detection of significant images: Area under the curves (AUCs) were 0.9982, 0.9981, and 0.9999 for test, validation, and training set images, respectively. ROC curve and AUCs shown that the training model is well fitted to all of training images as well as there is little degradation of validation and testing performance from the training model.
