Abstract

Features which are linearly dependent on other features do not contribute toward pattern classification by linear techniques. In order to detect the linearly dependent features, a measure of linear dependence is proposed. This measure is used as an aid in feature selection. Speaker verification experiments demonstrate the usefulness of employing such a measure in practice.
