| Abstract(in English) | In handwriting recognition integrating segmentation and classification, the underlying classifier is desired to provide both high classification accuracy and resistance to out-of-class patterns (outliers). To achieve this goal, this paper proposes a class-specific feature polynomial classifier (CFPC), which can be viewed as a hybrid of ordinary polynomial classifier (PC) and projection distance method. The class-specific features are extracted by K-L transform on class-specific space, unlike that the ordinary PC uses the principal components on the whole pattern space. The incorporation of class-specific residual of subspace projection (projection distance) into CFPC was shown to benefit both classification accuracy and outlier resistance. The connecting weights of CFPC are learned class-by-class to minimize the mean square error on a training dataset. In experiments of handwritten digit recognition and numeral string recognition, the performance of CFPC is comparable or better than those of ordinary PC, learning quadratic discriminant function (LQDF), and support vector machines (SVMs). |
