Webb29 maj 2024 · 3 provides the third step with the number of clusters to use. If no consolidation yields a CCC in excess of 3, the maximum number of clusters is selected. The number of clusters determined by the second step provides the value for k in a k-means clustering of the original training data cases. WebbThe classic k-means clustering algorithm performs two basic steps: An assignment step in which data points are assigned to their nearest cluster centroid.
