Clustering (slide from Han and Kamber)

Clustering (slide from Han and Kamber). Clustering of data is a method by which large sets of data is grouped into clusters of smaller sets of similar data. The example below demonstrates the clustering of balls of same colour. There are a total of 10 balls which are of three different
