Abstract
In conventional classification, an instance is classified in just one among two or more classes. These problems are called single-label classification problems. However, there are more complex problems in which an instance can be classified in two or more classes simultaneously. These are known in the Machine Learning literature as multi-label classification problems. When the classes involved are organized in a hierarchy, the task is even more challenging, and is known as hierarchical classification. Many practical applications are related to hierarchical and multi-label classification, like the classification of images, documents and music, and protein function prediction. These are very challenging tasks due the difficulty in considering the relationships between the many classes of the problem during training. Together with this, the unbalance of the datasets harm the performances of the classifiers proposed in the literature. Given the high space of possible classes, we propose the development of Multi-objective Evolutionary Methods for the generation of multi-label and hierarchical classification rules. The rules generated should satisfy the requisites of interpretability and good performance. The proposed methods will be compared with state-of-the-art methods in the literature, using hierarchical and multi-label datasets from the bioinformatics domain. The method will be evaluated with measures specifically proposed for hierarchical and multi-label problems. (AU)
