Paper Abstract

This paper proposes a new hierarchical multilayer perceptron (HMLP) network as an improved classifier for alpha-numeric character recognition from the automobile license plates. HMLP is built up by hierarchically stacking the small MLP subnetworks that work as local classifiers in the feature space. Each subnetwork is trained not to cause overtraining. The generalization and overtraining problem of neural networks was reduced by this method. The classification performance of HMLP was compared with the conventional single stage MLP, and HMLP showed better performance especially for the large sized classification problem.
