Influence of Personal Preferences on Link Dynamics in Social Networks

Figure 4

The plot of the ROC curve for prediction of edge formation in both the behavioral and cognitive networks for different thresholds of edge weight in the second semester (the curves for other semesters are similar). The curve shows that the models fit the data well, but that the higher the recall, the higher the false positive rate. The prediction in behavioral network performs a little better than it does in the cognitive network.
