Figure 5From: Application of nonnegative matrix factorization to improve profile-profile alignment features for fold recognition and remote homolog detectionROC 50 score using NMF features versus using original PPA features. The figure represents ROC50 score of NMF features versus that of original PPA features. Applying NMF degrades the performance for only 10% proteins in testing set but increases the performance for more than 70% proteins of testing set.Back to article page
