Contemno wrote:You told me to use AttributeSubsetPreprocessing, to select the attributes I need to process changes on.But this knot is only able to selct one attribute. Isn't it?Maybe there is a possibility to define more than one atrribute in "attribute_name_regex"?I need to define the attributes by name wich the following is processed on.
If you want e.g. to apply the inner operators on say two attributes called age and weight, the corresponding regular expression which lets you chose these attributes is age|weight .
