Experiment-C
In this experiment, we used the CT-data of the CTHVS where the normal cases and the COVID-19 cases were all from the Youan hospital. The results of the five evaluation indicators for the comparison of the COVID-19 cases and influenza cases of the CTHVS are shown in Table 3 where the influenza cases and the COVID-19 cases are all from the CTHVS. The CNNCF achieved the highest performance and the best score of all five evaluation indices. The ROC scores are plotted in Fig. 4c; the AUROC of the CNNCF is 1.0. The precision-recall scores are shown in Fig. 4f, and the AUPRC of the CNNCF is 1.0.
