WebVertex sets of each new sub-graph form a cluster pair. Thus, a bi-partition co-clusters vertices into two cluster pairs. Clusters of the same pair preserve all features of the original graph except by losing the connections with other cluster pairs. One way to measure the similarity between two concept clusters is the sum of weights for all edges WebJan 20, 2024 · As the number of clusters increases, the WCSS value will start to decrease. WCSS value is largest when K = 1. When we analyze the graph, we can see that the graph will rapidly change at a point and thus creating an elbow shape. From this point, the graph moves almost parallel to the X-axis.
