| Abstract: | The model of multilayer perceptron (MLP) and back-propagation (BP) training algorithm in artificial neural network are employed in this paper. New ideas are proposed to improve learning algorithm in aspects of learning rate for BP training. Experiment results are also presented to demonstrate the effect of improvement, which has a widely applied future for ultrasonic testing in industry. |
