摘要
在通过对ＢＰ算法加以改进；使其性能有所提高，收敛速度加快的基础上，提出了一种新的ＣＡＰＰ系统零件信息的输入方法；即零件的图纸经过扫描仪扫描获得数字信息、力。载神经网络模式识别，同时将数字信息还原成ＣＡＰＰ系统中计算机直接读懂的信息，并加载网络测试加以验证．
It is one of the important methods of pattern recognition to apply neural networks to target classification. Forward propagation multi-layers neural networks and its BP algorithm are used widely. In this article, some measures are taken to improve BP network, and to make its performance better and its convergence speed quicker. A new input method of mechanical parts information in CAPP system is raised. That is, the contents of the parts drawing are scanned into digital information by scanner and loaded on neural network recognizing the pattern, at the same time, the digital information is reverted which the computer can understand directly, furthermore, tested by loading neural network.
