A note on the orthonormal discriminant vector method for feature extraction

摘要

We propose a new feature extraction method based on the modified “plus e-take away f” algorithm and discuss an aspect of the optimization method used in sequential feature extraction, by comparing the proposed method with the orthonormal discriminant vector (ODV) method which belongs to a class of sequential feature extraction. It is shown from experimental results that the proposed method is superior to the ODV method in terms of the error probability.
