Clustering is the process of dividing a dataset into subsets, each of which is called a cluster (Cluster), and clustering makes the objects in the cluster highly similar, but unlike the objects in other clusters, the set of clusters generated by clustering is called a cluster. On the same data set, different clustering algorithms may produce different clusters.
Cluster analysis is used to gain insight into
