Figure 4

ROC 50 scores of various methods for remote homolog detection at the superfamily level. The mean ROC50 score of NMF feature (0.66) is better than those of original PPA (0.49). At > 0.90 ROC50 scores, 52% of proteins with NMF features correctly detect remotely related proteins, whereas by using original PPA features only 28% of proteins detect remote homologs and that of HHsearch is 39%.
