Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters).
K means clustering algorithm was developed by J. MacQueen (1967) and then by J. A. Hartigan and M. A. Wong around 1975. Simply speaking k-means clustering is an algorithm to classify or to group your objects based on attributes/features into K number of group.K is positive integer number. The grouping is done by minimizing the sum of squares of distances between data and the corresponding cluster centroid. means clustering algorithm was developed by J. MacQueen (1967) and then by J.
