摘　　要：为了比较不同的人工神经网络算法识别人民币序列号的性能,研究了离散Hopfield神经网络、BP神经网络、PNN神经网络、GRNN神经网络、SVM神经网络等五种算法的训练耗时、识别速度、识别率和抗噪声能力.研究结果表明,在五种算法中BP算法的综合表现最差,其次为SVM和Hopfield算法,而PNN和GRNN算法表现最好,不仅识别率最高、训练和识别时间最短,而且具有较强的抗噪声能力.To investigate the performance of different neural network algorithms in identifying serial number of RMB banknote, the training speed, recognizing speed and rate, and ability of anti-noise of five neural network algorithms, including the discrete Hopfield neural network, BP neural network, PNN neural network, GRNN neural network and SVM neural network, are studied. The simulation results show that amongst the five algorithms, BP performs worst, followed by SVM and Hopfield, with PNN and GRNN performs best, not only gives the higher recognition rate, shorter training and recognition time, but also is more robust to noise.
