Feature selection techniques are aimed towards finding an optimal feature set for a specific purpose, such as the optimization of a biometric system verification performance. In general, feature selection algorithms try to avoid the evaluation of all the possible feature combinations when searching for an optimal feature vector, since these grow exponentially as the number of feature increases.
