One-Class SVM

Hi all,

 

I have a problem while trying to build a model with LibSVM (One-class SVM) operator. 

Label is Polynomial, but i transformed it in Binominal, and later (like from stackoverflow) had Filtered dataset to show only those cases which are "true". After Filter examples, I used Map operator, and then libSVM.

On test side of CrossValidation, after ApplyModel, I used Map operator where the selected attribute is prediction, and values for mapping are: inside -> true, and outside -> false. 

Unfortunately, every time I start the process, I get an error: "java.lang.UnsupportedOperationException".

 

Thanks in advance for your help!

Best wishes,

Milos Panic

    Dear Thomas,

    Sure. This dataset is from one of competitions on Kaggle.

    And it is reduced to 30% of cases.

     

    Thanks in advance,
