2021-9-22 Introduction to Data Mining. This is a data mining method used to place data elements in their similar groups. Cluster is the procedure of dividing data objects into subclasses. Clustering quality depends on the way that we used. Clustering is also called data segmentation as large data groups are divided by their similarity.
