Comparison of FWM with LRM, NBM, and SVM. Four AUC matrices among the 21 species are produced using the four methods. AUC scores (m _ij ) in the same position of the four matrices are then sorted and replaced with markers (first with the maximum AUC score, followed by the second and third, and, finally, fourth with the minimum score) for the four methods. By calculating the frequency of the ranking list (i.e., first, second, third, and forth) in the four matrices, performance distributions for the four methods were generated. The AUC score with ranking the first and second can be classified as high-quality performance, while third and fourth can be classified as low-quality performance. Significant differences are tested by Fisher’s exact test, and the results are shown in the lower triangular table.
