Intelligent Miner® includes a module for automatic variable selection. This module determines the usage type of input fields. If the module determines a field not to be useful for the mining process, the field is considered inactive during the generation of the mining model.
For classification and regression, you can let the automatic variable selection determine the active fields and the inactive fields in your input data. You can also control the automatic variable selection by specifying a usage type for a field.
You must set the target field explicitly, it is not set automatically.
