Web2.2 Binary Relevance In practice, the Binary Relevance (BR) method is a popular means of addressing the multi-label learning problem. In this method, the problem is transformed into a set of jLjbinary classiﬁcation problems, where each problem corresponds to a speciﬁc label. A separate classiﬁer is trained for WebBinary relevance. This problem transformation method converts the multilabel problem to binary classification problems for each label and applies a simple binary classificator on these. In mlr this can be done by converting your binary learner to a wrapped binary relevance multilabel learner.
