摘要
针对传统的BP神经网络应用于藻类生长预测时,往往出现训练时间较长、输出数据精度低等问题。本文提出了在含有两层隐含层的BP神经网络结构中,对于数量一定的神经元,若神经元在隐含层分配合理,则BP神经网络可以达到减少训练次数并且能满足问题精度的要求。应用实例表明,该方法对预测藻类生长显得非常有效。
Traditional methods based on BP nellral network for forecasting alga＇s growth has the problems of training time is too long, and data＇s precision is not enough. This paper gives a method on how to distribute a certain number of neuron to a BP neural network＇s two hidden layers. This method can reduce BP neural network＇s training time and can satisfy the data＇s precision. Experiments are done to explain and verify this method.
