BP神经网络算法的一种改进及在小麦赤霉病预测中的应用
The Improment of BP Neural Network and Applicationin Forecasting of Wheat Scab
【摘要】 针对BP网络收敛速度慢,计算量大等缺点,提出了动量法和批处理梯度下降学习算法相结合的BP神经网络改进算法,用以提高BP网络训练速度。该方法成功地实现了小麦赤霉病流行程度预测,效果显著。
【Abstract】 Amming at the disadvantages of low speed and large computing of BP neural network ,the present paper proposed a method which used momentum combined with batch processing-gradient descent to inhance the speed of BP network. The method has forecasted the transmission situation successfully and the effect remarkbale.
