Towards the optimal feature selection in high-dimensional Bayesian network classifiers

Pavlenko Tatjana, Hall Mikael, von Rosen Dietrich, Andrushchenko Zhanna


We focus on Bayesian network (BN) classifiers and formalize the feature selection from a perspective of improving classification accuracy. To exploring the effect of high-dimensionality we apply the growing dimension asymptotics. We modify the weighted BN by introducing inclusion-exclusion factors which eliminate the features whose separation score do not exceed a given threshold. We establish the asymptotic optimal threshold and demonstrate that the proposed selection technique carries improvements over classification accuracy
