An Overview of Multilabel Classifications

We are very familiar with the single-label classification problems. We mostly come across binary and multiclass classifications. But, with the increasing applications of machine learning, we face different problems like movie genre classifications, medical report classification, and text classification according to some given topics. These problems can't be addressed using single-label classifiers, as an instance may belong to several classes or labels at the same time. For instance, a movie can be of Action and Adventure genre at the same time.
