METHOD OF COMBINING MULTIPLE EXPERTS FOR THE RECOGNITION OF UNCONSTRAINED HANDWRITTEN NUMERALS

For pattern recognition, when a single classifier cannot provide a decision which is 100 percent correct, multiple classifiers should be able to achieve higher accuracy. This is because group decisions are generally better than any individual's. Based on this concept, a method called the ''Behavior-Knowledge Space Method'' was developed, which can aggregate the decisions obtained from individual classifiers and derive the best final decisions from the statistical point of view. Experiments on 46,451 samples of unconstrained handwritten numerals have shown that this method achieves very promising performances and outperforms voting, Bayesian, and Dempster-Shafer approaches.
