人工神经网络在区域地质调查中的应用——反向传播模型(BP网)建立与应用

Application of artificial neural net to geological mapping: setting up and utilization of backward propagating (BP net)model

类比与识别是１∶５ 万区调工作中应用的基本方法之一。把人工神经网络技术———反向传播模型（ＢＰ网） 应用于这些基本方法中，不但有助于区调技术人员使脑科学朝向定量、精确和理论化方向发展，而且有助于我们对神经网络及其成为一种崭新的信息处理方法的理解，从而提高１∶５ 万区调理论研究水平。

Analogy and identification method is one of the basic approaches in 1∶50 000 geological mapping.Application of the artificial neural net technology backward propagating (BP net)to these methods will not only help to improve quantification,increase precision and theory development,but also help us to better understand this new information technology.
