    public class NumericToBinary
    extends PotentialClassIgnorer
    implements UnsupervisedFilter, StreamableFilter
    Converts all numeric attributes into binary attributes (apart from the class attribute, if set): if the value of the numeric attribute is exactly zero, the value of the new attribute will be zero.
