Is there a method in Knime to make CBO oversampling

I need to oversample my minority class. I'd like to know if there's a method in knime like CBO. I have found just SMOTE till now.

What does CBO stand for?

You could always use Bootstrap node - together with group loop start and some flow variables, it could be extended to work by strata. Otherwise you might find your luck with the R node and an appropriate package therein.
