Comparison of precisions of five methods on different perturbation ratios on Email network.
We compared precisions of all indices with perturbation on Email, which are SPM, NMF − D1, NMF − A1, NMF − D2 and NMF − A2. Different fractions of training set f are 0.6, 0.7, 0.8 and 0.9. The x-axis is perturbation ratio η varied from 0.02 to 0.1. The y-axis is the precision averaged over 100 independent runs.
