The top part refers to existing partitions and the bottom part to the unsupervised partitions. Results were obtained averaging over 28 days, with standard deviations taken as error bars.
A fundamental problem in network analysis is clustering the nodes into groups which share a similar connectivity pattern. Existing algorithms for community detection assume the knowledge of the number
Understanding community structures is crucial for analyzing networks, as nodes join communities that collectively shape large-scale networks. In real-world settings, the formation of communities is of
