摘要
基于人工神经网络(ANN)中自组织特征映射网络(SOM)的聚类功能,采用统计年鉴中城市非农行业就业人口的资料,运用MATLAB2010软件的神经网络工具箱,对陕西省10个地级市城市综合职能进行分类,最终将10个地级市分为5类,并对分类结果进行分析和讨论.结果表明,人工神经网络方法实际可行.
Based on the clustering function of self-organizing feature map in ANN,the article selects some datus of urban population from the Shaanxi province yearbooks to classify the cities’ functions by using the neural network toolbox in MATLAB 2010.The 10 cities in Shaanxi province are classified into 5 groups according to their comprehensive urban functions.Furthermore,the results of classification are analysed and discussed,which reveals the method is feasible in actuality.
