Fig. 3From: Clustering 1-dimensional periodic network using betweenness centralityEdge-betweenness clusters using betweenness values on static graph (left) and periodic graph (right); Each node represents a student, and the color of each node represents the class of a student corresponding to the node. The edges shown in the figures are edges that remained after we remove edges with high betweenness centrality. Each connected component in the remaining graphs represents a cluster of nodesBack to article page
