Abstract
Discrete support vector machines (DSVM), recently proposed in [lo] and [ l l ]
for binary classification problems, have been shown to outperform other
competing approaches on well-known benchmark datasets. Here we address their
extension to multicategory classification, by developing a one-against-all
framework in which a set of binary discrimination problems are solved by means
of DSVM. Computational tests on publicly available datasets are then conducted
to compare multicategory DSVM with other methods, indicating that the
proposed technique achieves high accuracies.
1 Introduction
Classification problems with multiple categorical target classes play a central
role in several applications of data mining in such diversified fields as marketing,
finance, fraud detection, text and speech categorization, medical
