Hi,

I know that the operatorNumeric2Polynominalmapsallattributes' numeric values to the corresponding nominal values. If I understood correctly, it'sonlythe attributes' values that are mapped, and not the label (whose numerical value is to be predicted).

Is there a way (or an operator) to maponly的数值someattributes to the corresponding nominal values? I would actually need it for all but one attribute.

Thanks,
Geo

    Hi,

    yes, for this purpose the operator "AttributeSubsetPreprocessing" can be used. The attributes on which the inner operators should be applied can be defined via regular expressions. This example applies a discretization on all attributes but on attribute "att3":
