Discretize by User Specification


Synopsis

Discretize numerical attributes into user defined bins.


Description

This operator discretizes a numerical attribute to either a nominal or an ordinal attribute. The numerical values are mapped to the classes according to the thresholds specified by the user. The user can define the classes by specifying the upper limits of each class. The lower limit of the next class is automatically specified as the upper limit of the previous one. A parameter defines to which adjacent class values that are equal to the given limits should be mapped. If the upper limit in the last list entry is not equal to Infinity, an additional class which is automatically named is added. If a '?' is given as class value the according numerical values are mapped to unknown values in the resulting attribute.
