+Clustering algorithms are useful in information theory, target detection,

+supports vector quantization and the k-means algorithms.
+
+:mod:`scipy.cluster.hierarchy`
+
+The `hierarchy` module provides functions for hierarchical and
+agglomerative clustering.  Its features include generating hierarchical
+clusters from distance matrices, computing distance matrices from
+observation vectors, calculating statistics on clusters, cutting linkages
+to generate flat clusters, and visualizing clusters with dendrograms.
