The objective function of the K-means is within-cluster sum of squared errors (SSE). SSE is squared sum of different between each observation and the cluster centroid. The optimal number of clusters, K, can be found by drawing sum of squared errors vs number of clusters point. WebNov 2, 2024 · Dendrogram. The agglomerative nesting is visually represented in a tree structure, the so-called dendrogram.For each step, the graph shows which observations/clusters are combined. In addition, the different horizontal extents (i.e., how far each cluster combination is from the right side of the graph) give a sense of the … korean traditional bow to elders
