Link Prediction in Weighted Networks: A Weighted Mutual Information Model
Table 1
Comparison of WMI-based methods with other typical unweighted indices measured by Precision (top-100) on four networks.
Each value is obtained by averaging over 100 independent runs of random division of training set and probe set. The abbreviations WMI-WCN*, WMI-WAA* and WMI-WRA* represent highest Precision values obtained by Eqs (19)–(21), respectively. The optimal values of α are presented in Table 2. The best performance in each network is marked by bold font.
