| Abstract(in English) | When a large number of reference patterns are available, or the feature size is very large, a nearest neighbor classifier needs large computational time. Hence, some fast algorithms for searching a nearest neighbor of an input pattern have been proposed. However, it is not known which of the fast algorithms is best for a handprinted character recognition system. In this paper, we compare several fast algorithms in terms of CPU time for searching a nearest neighbor. Experimental results show that MPS method and Fukunaga's mathod well perform. |
