abstract = "The fact that principal component analysis (PCA) does not
necessarily represent important discriminant directions to
separate sample groups motivates the development of the
multi-class discriminant principal component analysis (MDPCA).
This technique addresses the problem of ranking face features in
N-class problems computed by PCA components (eigenfaces). Given a
database, the MDPCA builds a linear support vector machine (SVM)
ensemble to get the separating hyperplanes that are combined
through an AdaBoost technique to determine the discriminant
contribution of each PCA feature. In this paper, we follow the
MDPCA methodology but we replace the SVM by the linear perceptron
as the basic learner in the AdaBoost approach. In the
computational experiments we compare the obtained technique,
called MDPCA-Perceptron, with the PCA and the original MDPCA
through facial expression experiments. Our computational results
have shown that the principal components selected by the
MDPCA-Perceptron allow competitive recognition rates in lower
dimensional spaces with promising results for reconstruction tasks
as well.",
