Principal components analysis (PCA) is one of the most widely used
techniques in machine learning and data mining. Minor components
analysis (MCA) is less well known, but can also play an important role
in the presence of constraints on the data distribution. In this paper we
present a probabilistic model for "extreme components analysis" (XCA)
which at the maximum likelihood solution extracts an optimal combina-
