文章利用MATLAB编程软件,分别建立RBF神经网络和BP神经网络,采用《中国人口统计年鉴》中1999-2003年男性人口总数量作为样本,分别对RBF神经网络和BP神经网络进行训练,并预测后5年后男性人口数量.结果表明这两种方法预测人口均是可行的,效果较好,误差很小.
Using MATLAB software,we respectively established the RBF neural network and the BP neural network,and adopting the China statistical yearbook in 1999-2003 the total number of male population as a sample,RBF neural network and the BP neural network are trained and male population of the next five years is predicted.The results show that the two methods about predicting population are feasible and can achieve better effects,while error is very insignificant.
