In pattern recognition, to increase the number of prototypes is a simple method to improve accuracy. In this paper, we use over 830,000 manually labeled handwriting patterns, and we examine an effect of the number of prototypes on the handwriting numeral recognition. The analysis result showed the error rate decreases about 40% by increasing the number of prototypes 10 times. Other analysis results showed the changing situation of feature space when the number of prototypes increased.
