5. Comite de maquinas : uma abordagem unificada empregando maquinas de vetores-suporte / Committee machines: a unified approach using support vector machines
Algorithms based on kernel methods are prominent techniques among the available approaches for machine learning. They were initially applied to implement support vector machines (SVMs). The SVM approach represents a nonparametric learning procedure devoted to high performance classification and regression tasks. However, structural and parametric aspects of
