Converting numerical label to binomial ??
I'm just getting into RapidMiner and have a question about the label type of examples.
Some learners need nominal labels, but my data file has +1 & -1, which is recognized by CVSExampleSource as numerical.
I tried Numerical2Binomial, but that converts all attributs and not only my label attribute.
Finally, I used the AttributeDescriptionFileWizard to specify the type of my label attribute.
That works, but I wonder if I could also solve this problem using an operator ??
