<TD>Reduces the dimensionality of the data by projecting 
 it onto a lower dimensional subspace using a random 
 matrix with columns of unit length (It will reduce 
 the number of attributes in the data while preserving 
 much of its variation like PCA, but at a much less
 computational cost).</TD>
