An Optimum Classifier Approximation for NetworkBased Handwritten Character Recognition
"... An approximation of the Bayes decision rule and its implementation on a twolayered network are described. The net is trained in two phases: first, probabilities of the discretevalued input features are learnt by applying a GoodTuring based estimator; second, net weights are estimated by applying ..."

An approximation of the Bayes decision rule and its implementation on a twolayered network are described. The net is trained in two phases: first, probabilities of the discretevalued input features are learnt by applying a GoodTuring based estimator; second, net weights are estimated by applying an adaptive gradient descent technique. Experiments were performed on a database of 67,000 real life handwritten numerals. By using input units that read subpatterns of the character bitmap, a recognition rate of 93.30% is achieved, with 1.39% substitution rate. The paper shows that computational complexity and implementation characteristics make this approach a possible competitor of artificial neural networks described in the literature. 1 Introduction Classification is the problem of mapping a set of patterns into a fixed number of classes. With a statistical approach, classification is usually based on an a posteriori probability. Moreover, many nonstatistical classifiers can be seen...
