Read AML only allow me to have one output!

Hi there,

I try to simulate a classification problem with a dataset with 13 inputs and 4 outputs and the "Read AML" operator only allows to mark one feature as "label", the rest is set to "attribute". How can I deal with that?

Many thanks in advance
Theo

Hi,

most operators in RapidMiner can handle only exactly one output variable - in RapidMiner-terms the "label". You can however specify custom roles, such as "label1", "label2" etc. Before applying a learner on your data, you have then to use Set Role to assign the role "label" to one of your attributes. That one will then be used as output/target variable by the algorithm.

To get a better understanding of the concept of attribute roles, please have a look at the introductory video tutorials on our website.

Best,
Marius
