One class classification

I came across a good learning resource about one class classification:

In practice, weka provides two ways of doing one-class classification: one is under libsvm package; the other one is named: OneClassClassifier (, which is a meta classifier. In this case, you need to choose a basic classifier to go on.

From an experiment of the data set I collected, I noticed that OneClassClassifier with random forest as basic classifier performs better than one-class classification of SVM.
