1) tell me how to use one class svm for poynomial and binomial attributes
Thank you

a SVM is simply not supporting nominal values by design. You can use Nominal to Numiercial to change the type. Then you would most likely create a dummy coding.
cheers,

I have used nominal to numerical operator but after that also it showing same errror.
My data looks like this
a1 a2 a3 a4 a5
date polynomial binomial error(one class label) prediction
i am predicting error from this but it is showing
one class svm not supported yet
so
please help me regarding this.
I have already sent process xml file
