This figure above is the NMI similarity matrix of the preference-value based method for six real networks. Here, a Zachary’s Karate Club, b Tortoise Social, c Facebook Caltech, d EU Road, e Facebook Nips and f Indo-china Webgraph. The three values of \(\nu = [065,0.75,0.85]\) have been compared to other existing algorithms based on NMI and results are compared through this similarity matrix of clustering scoring
