Our group is interested in the study and development of machine learning techniques mainly for classification, feature learning, active learning, temporal series analysis, feature selection, and clustering purposes. Thus, our research very often includes development and adaptation of supervised and unsupervised learning approaches, typically based on Neural Networks, Evolutionary Algorithms, and Support Vector Machines. We also work on strategies to improve the effectiveness of classification systems by more effective ensemble of classifiers according to applications needs. Finally, we are very interested on the development of new active learning strategies aiming at the inclusion of the user in the training process.
