Explain clustering algorithm?

"""Cluster is a collection of objects which have similarity between then and are

from objects different clusters.""

Following are the ways a clustering technique works:

- Exclusive:

A member belongs to only one cluster.

- Overlapping:

A member can belong to more than one cluster.

- Probabilistic:

A member can belong to every cluster with a certain
amount of probability.

- Hierarchical:

Members are divided into hierarchies, which are
sub-divided into clusters

at a lower level. "
