9.1 Introduction

Feature selection attempts to find the most discriminative information aiming to design an accurate learning system. It is often desirable to find features that are simple to extract, invariant to geometric and affine transformations, insensitive to noise, and useful for characterizing patterns in different categories (Duda et al., ...
