Reduction Methods on Multi-label Data based on Granular Computing

Multi-label classification (MLC) is one specific type of classification. In a multilabel dataset, an object can belong to several classes at the same time, that is, more than one class label can be associated with the same object. In the context of multi-label classification, most data reduction methods have been addressed to the selection and extraction of features, and discretization. For this reason, we propuse three methods of instance selection, and three

methods of instance generation (prototypes). The former are relying on the Rough Set Theory (RST), which is one of the most representative theories within Granular Computing. On the other hand, the prototype generation methods are capable of generating a set of new objects in the application domain from the initial objects. Our proposal is based on two different ways of the granularity of the information. The methods proposed in these researches are independent of the learning algorithm to be used.

We explore the global performance of our methods when coupled with the ML-kNN algorithm. We leaned upon several multi-label training sets taken from the MULAN and RUMDR repositories.
