WebClustering analysis is widely used in many fields. Traditionally clustering is regarded as unsuper-vised learning for its lack of a class label or a quantitative response variable, which in contrast is present in supervised learning such as classification and regression. Here we formulate clustering as penalized regression with grouping pursuit.
