Cluster Analysis
In k-means clustering, you select the number of clusters you want. The algorithm iteratively estimates the cluster means and assigns each case to the cluster for which its distance to the cluster mean is the smallest. In two-step clustering, to make large problems tractable, in the first step, cases are assigned to “preclusters.”

Nonetheless, some work in graph partitioning and in image and market segmentation is related to cluster analysis.
