Research on Expert System of Crop Disasters Based on Neural Network

摘要：

Crop disasters require diagnosis,then an improved neural network with weight adjustment of forecasting model is proposed.The crop disasters are regarded as example,after the symptoms of disasters and features are classified,abstracted and coded,the adjustment of weight,optimization of network structure and reasonable adjustment of parameters of BP neural network are discussed,then a model is constructed to forecast the disasters of crop,the weight is used as knowledge to predict disasters of crop through studying training samples.Results have shown that the optimization expert system of crop disasters based on neural network has greatly improved the accuracy and reliability of crop diagnosis.
