Abstract(in English) Although the discriminant analysis has been most widely known as a typical statistical feature selection technique, its availability to small class classification problems is limited because the number of selectable features can not be or exceed the number of classes. In order to remove the limitation, a new feature selection technique ( F-K-L ) is proposed and tested by a handwritten numeral recognition experiment. While the discriminant analysis maximizes the variance ratio ( F-ratio ), and the principal component analysis ( K-L expansion ) minimizes the square error of representing a mixture distribution of total class, the F-K-L optimizes both the F-ratio and the square error simultaneously. The result of experiment shows that the F-K-L provides the richest features in discriminating power for the small class classification problems when compared with other techniques including the discriminant analysis, the principal component analysis, and the orthonormal discriminant vector method ( ODV ).
