Negative class in polynomial labels? - Binary2MultiClassLearner
I have the following problem (and I hope that I will describe it understandably):
I am processing a dataset containing polynomial labels including n-1 "positive" labeltypes and one negative (standard) label-type.
I am using the Binary2MultiClassLearner because the learner I use is a binary SVM.
The problem now exactly is, that the "negative" class dominates the dataset and the SVM just predicts the "negative" class .
For binominal labels it is possible to define the positive class. It would be nice if one could define the negative class for my problem, is this possible?
