Converting label from pseudo polynomial to binomial ??

Axel

Hi everybody,

I have a data set with polynomial labels.
I use ExampleFilter to remove examples from the data set so that effectively only examples from two classes remain.
But RapidMiner still thinks that the data are polynomial and not binomial and I'm now looking for an operator to fix this.
Is Nominal2Binomial the correct way?  It creates new attributes which is not really what I want...

Thanks,

Axel

Okay, I found a solution !

AttributeSubsetPreprocessing        => Isolate my label attribute
  Nominal2Binominal                         
  AttributeFilter                                => Remove unwanted attributes generated by Nominal2binominal
ChangeAttributeRole                      => Recreate label type

after all, not that difficult  :-)
