This code calculates the Silhouette cluster validity index . It can be used to determine the optimal number of clusters.
The Silhouette index is an internal cluster validity index, which measures the quality of a partition. [Reference: P. J. Rousseeuw (1987). "Silhouettes: A Graphical Aid to the Interpretation and Validation of Cluster Analysis". Computational and Applied Mathematics. 20: 53–65. doi:10.1016/0377-0427(87)90125-7].
The Silhouette index varies between -1 and 1. Higher values signify a better partition.
