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. ...
