Data balance. Most classes adopt random undersampling, while a few classes adopt smote method to oversample to obtain relatively balanced data;
mi_balance_data.RdData balance. Most classes adopt random undersampling, while a few classes adopt smote method to oversample to obtain relatively balanced data;
