+restricted and meaningful molecular signatures from complex and high-dimension
+data, and to build robust classifiers.  This package implements a method to
+assess the relevance of the variables for the prediction performances of the
+classifier.  The approach can be run in parallel with the PLS-DA, Random
+Forest, and SVM binary classifiers.  The signatures and the corresponding
+'restricted' models are returned, enabling future predictions on new
+datasets.")
