| Abstract(in English) | When we design a statistical pattern classifier, it is well known that classification performance remarkably decreases in the case of limited sample size, because of estimation errors of covariance matrices. Friedman proposed Regularized Discriminant Analysis(RDA) to deal with this problem as one of the method of designing classifier. RDA needs two parameters, but no practical method on how to decide the value of these parameter has been proposed. Authors found a simple equation to decide one parameter of RDA and confirmed its effectiveness making use of Monte Carlo simulation. They also applied this practical method to the character recognition experiments and got good results. |
