The Challenges of Clustering High Dimensional
... Cluster analysis is a classification of objects from the data, where by “classification” we mean a labeling of objects with class (group) labels. As such, clustering does not use previously assigned class labels, except perhaps for verification of how well the clustering worked. Thus, cluster analys ...
