What is Clustering?
Clustering. Sometimes called segmentation, clustering identifies people who share common characteristics, and averages those characteristics to form a “characteristic vector” or “centroid.” Clustering systems usually let you specify how many clusters to identify within a group of profiles, and then try to find the set of clusters that best represents the most profiles.Clustering is used directly by some vendors to provide reports on general characteristics of different visitor groups. These techniques require training, and suffer from drift on Web sites with dynamic Web pages.
