Hey Xue Jia, I apologize for my belated response. Regarding your question, you must differentiate the ensemble-building algorithm from the learner used. The PU bagging method uses the bagging method to build an ensemble classifier, which can be used with any base learner Now, a few notes:
Regarding the two-step method, if I remember correctly, any classifier that outputs probabilities can be used as the base learner there. Cheers, |

Hello:
The reference of PU bagging is "A bagging SVM to learn from positive and unlabeled examples", but the code is not the SVM, But is the Random forest. Does that mean any classifier learner (SVC, Decision tree, Random Forest, etc) can be applied in this bagging method? and so are the Standard classifier and two-step methods ?
Looking forward to your reply.
sincerely yours
Xue Jia
