The paper presents a method for combining a neural network and rejection units. Coventional neural network systems have such a drawback that they do not reject a garbage input pattern but always classify it as one of the predetermined outputs. This drawback is overcome by incorporating rejection units to the conventional MLP neural networks. A new concept has been proposed and applied to the design of the rejection units and the neural network. Several tests have been carried out to evaluate the performance of the proposed system in terms of the recognition rate, rejection rate and reliability. The simualtion results show that the proposed system performs better than the conventional ones.
