Hello! I have a doubt about Data Mining, perhaps this message would have to be commented in a data-mining forum I am with a classification problem. I have 4 classes: g0,g1,g2,g3. These are my factors. The question is : Is it possible to apply oversampling in a problem with more than 2 classes ? I do this question because I have read many papers but all these papers only consider 2 classes. Any help is welcome! Thanks in advance! Regards! [[alternative HTML version deleted]]
