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. If the value of the numeric attribute is missing, the value of the new attribute will be missing. Otherwise, the value of the new attribute will be one. The new attributes will be nominal. Valid options are:-unset-class-temporarily Unsets the class index temporarily before the filter is applied to the data. (default: no)
