Abstract :
In this paper, a two-stage approach for pattern recognition problems of large scale is proposed. The approach consists of two steps, where two new technologies are developed. The first one is a neural network construction method that can be used to build very complex decision boundaries for difficult pattern classification tasks. The second is a coarse classification method that takes speed and accuracy into consideration at the same time. And the maximum size of the resulted cluster is controlled in order to avoid too much difference among the size of resulted clusters. Recognition of 1000 hand written Chinese characters is used to test the performance of the approach and the results are promising
