Types of clustering

Cluster analysis is all about the kind of algorithms that can be used to find clusters automatically given the data. There are primarily two classes of clustering algorithm; they are as follows:

• The Hierarchical Clustering algorithms
• The Partitional Clustering algorithms
  

The Hierarchical clustering algorithms define clusters that have a hierarchy, while the partitional clustering algorithms define clusters that divide the dataset into mutually disjoint partitions.

Hierarchical clustering

The Hierarchical clustering is about defining clusters that have a hierarchy, and this is done either by iteratively merging smaller clusters into ...
