The feature reduction problem is considered in the context of two equiprobable classes with multivariate pattern vectors. Three methods for feature selection, that are often referred to in the literature, under conditions which deviate from theoretical assumptions, are compared. If the purpose of the feature reduction is well defined and the scatter characteristics of the classes are well estimated, it is possible to determine the optimal method for a specific practical system.
