Abstract

The problem of feature selection in statistical pattern recognition is addressed. After formulating feature selection as a combinatorial optimisation problem, a taxonomy of approaches to feature selection is introduced. The techniques available in the literature can be logically grouped into two main categories depending on the form of density functions involved. Recent advances i the methodology of feature selection are then overviewed in this taxonomical framework. The methods discussed include the latest variants of the Branch & Bound algorithm, enhanced Floating Search techniques and the simultaneous semiparametric pfd modelling and feature space selection method.
