结合灰色GM(1,1)预测模型和BP神经网络2种预测模型的优点,提出了一种灰色神经网络模型,并用该模型对蚌埠市小麦产量进行预测。结果表明,灰色神经网络预测精度高于单一的灰色GM(1,1)预测模型或BP神经网络。
Abstract Combining with the advantages of two kinds of gray GM ( 1,1 ) and BP neural network forecasting models, the study put forward a kind of gray neural network model, and wheat yield in Benggbu City was forecasted by this model. The result showed that forecasting precision of gray neural network model was higher than single gray GM( 1,1 ) model or BP neural network model.
