Associated research grant:09/16206-1 - New trends on optimum-path forest-based pattern recognition, AP.JP


Traditional pattern recognition techniques associate one label to each dataset sample considering aprevious knowledge obtained from a training dataset, which can be labeled or not. In the first case,each sample can be labeled automatically or manually by a technician. However, in many situations,a given sample can be labeled by more than one label. Medical diagnostic systems, for example,can diagnose more than one disease for a patient. Applications of musical recommendation, widelyused in social networks, can be trained using labels offered by user in a subjective way. Otherinteresting application concerns with the classification of documents, which can be associated tomany classes at the same time, such as religion and theater, for example. In this context, the present research projectproposes to study several multi-label methods and develop a multi-label method using theOptimum-Path Forest classifier, which was recently proposed in the literature and has not been employed to thispurpose so far. This project also proposes to include the algorithms generated here in the LibOPF, which is an open sourcelibrary written in C Programming Language and aims the development of classifiers based on optimum-path forest. As new versions of the library will be published, this project will contribute for new functionalities of its. Some datasets will be used to validate the work.
