1. Seleção de componentes em ensembles de clasificadores multirrótulo / Component Selection in Ensembles of Multi-label Classifiers
The selection of components in ensembles of classifiers is a very common activity in the field of Machine Learning with several studies showing its effectiveness in obtaining significant gains in accuracy. However, the most studied classification task involves mutually exclusive labels (classes). The objective of this work is to present a study on the select

2. Abordagens para aprendizado semissupervisionado multirrótulo e hierárquico / Multi-label and hierarchical semi-supervised learning approaches
In machine learning, the task of classification consists on creating computational models that are able to automatically identify the class of objects belonging to a predefined domain from a set of examples whose class is known a priori. There are some classification scenarios in which each object can be associated to more than one class at the same time. Mo

3. Classificação multi-rótulo hierárquica de documentos textuais
The amount of information stored in text databases is steadily increasing. As such, demand for automated techniques to organize this data also continues to grow. In this context, academic and industry research has been focused on the study of automatic text classification. Most work on text classification studies the development of techniques in which there

5. A machine learning approach to automatic music genre classification
This paper presents a non-conventional approach for the automatic music genre classification problem. The proposed approach uses multiple feature vectors and a pattern recognition ensemble approach, according to space and time decomposition schemes. Despite being music genre classification a multi-class problem, we accomplish the task using a set of binary c
