Receiver operating characteristic (ROC) curves of the two-stage DL diagnostic system across five-fold cross-validation.
(a) ROC curves of stage one (diagnosis of pneumonia CXRs vs. normal CXRs). (b) ROC curves of stage two (diagnosis of COVID-19 CXRs vs. other viral pneumonia CXRs). AUC (Area Under the Curve) quantifies the overall diagnostic performance for each stage.
