From: Normalized L3-based link prediction in protein–protein interaction networks
Changes in scores for different link predictors when an ideal L3 graph is modified by: a removing compatible edges; and b adding incompatible edges. The shaded regions denote the variance (the minimum and maximum values) among repeated simulations, and the solid lines denote the medians. The AUC bar charts correspond to the respective plots. In b, a Savitzky-Golay filter using a polynomial of degree 3 and a window size of 21 was applied to make the curves smoother
