[0100] (1) Database analysis:
[0101] We performed global LOOCV, local LOOCV and FFCV with the HMDD database for evaluation on ICFMDA. To evaluate the performance of ICFMDA, we use five state-of-the-art methods for comparison. They are HGIMDA, RLSMDA, HDMP, WBSMDA and RWRMDA. In LOOCV, each known miRNA-disease association is sequentially picked as a test sample, while others are used as training samples. All untested associations are used as candidate samples. In local LOOCV, test samples are ranked among candidate samples for the disease they belong to, while in global LOOCV, all candidate samples are ranked. If the ranking of the test sample is not lower than the given threshold, the prediction is considered true. If the candidate sample's rank is not lower than a given threshold, the prediction is considered a false positive. Receiver operating characteristic (ROC) curves were plotted by calculating the true positive rate (TPR) versus the false positive rate (FPR) at ...
