WebJun 8, 2024 · Binary Relevance. In this case an ensemble of single-label binary classifiers is trained, one for each class. Each classifier predicts either the membership or the non-membership of one class. The union of all classes that were predicted is taken as the multi-label output. This approach is popular because it is easy to implement, however it ... http://palm.seu.edu.cn/zhangml/files/FCS
