This estimator uses the binary relevance method to perform multilabel classification, which involves training one binary classifier independently for each label. WebOct 26, 2016 · For binary relevance, we need a separate classifier for each of the labels. There are three labels, thus there should be 3 classifiers. Each classifier will tell weather the instance belongs to a class or not. For example, the classifier corresponds to class 1 (clf[1]) will only tell weather the instance belongs to class 1 or not. ... http://palm.seu.edu.cn/xgeng/files/fcs18.pdf on the plus side catalogue
