基于神经网络的草地退化决策专家系统设计

Design of Grassland Degradation Decision Expert System based on Neural Network

笔者对基于神经网络的三江源草地退化决策系统进行了总体设计,包括人机接口模块、知识库模块、神经网络模块及推理机模块,并介绍了各模块的具体功能,最后重点介绍了BP神经网络的详细设计,整个BP神经网络由3层结构构成,输入层结点数为5、输出层结点数为5、隐含层结点数为6。

The author gives the overall design of neural network based on the Sanjiangyuan grassland degradation decision system,including man-machine interface module,knowledge base module,neural network module and reasoning module,and introduces the specific functions of each module,and finally focuses on the detailed design of the BP neural network,the BP neural network consists of 3 layers.The input layer nodes is 5,the output layer nodes is 5,the hidden layer nodes is 6.
