To get the discretized data in numerical format enter "num". To get the discretized data in interval format enter "symb". |
In case of datasets containing negative values apply first a range normalization to change the range of the attributes values to an interval containing positive values. The discretization process becomes slow when the number of variables increases (say for more than 100 variables).
