Compare clusters is a tool to identify the optimal number of clusters for K-means clusteringClustering using the Davies-Bouldin index. The Davies-Bouldin index is a measure of cluster quality where a lower value indicates more optimal better clustering, i.e., the separation between points within the clusters is low (tight clusters) and separation between clusters is high (distinct clusters).

- Click a point on the plot to select it or type the number of clusters in the text box Partition data into clusters
Selecting a point sets it as the number of clusters to partition the data into. The number of clusters with the lowest Davies-Bouldin index value is chosen by default.
...
A K-means clustering task node and a Clustering result data node are produced. Please see our documentation on K-means clusteringClustering for more details.
