%description
Machine learning algorithms for predictor variables that are compositional
data and the response variable is either continuous or categorical.
Specifically, the Boruta variable selection algorithm, random forest,
support vector machines and projection pursuit regression are included.
Relevant papers include: Tsagris M.T., Preston S. and Wood A.T.A. (2011).
