摘要 提出了一种复杂系统最佳聚类数的确定方法,首先检验系统的可聚性,然后给定合理的聚类数区间,最后在聚类数区间中搜寻得到最佳聚类数,其中搜寻依据为尽可能满足经典的聚类有效性指标。对X30及Ben-said数据检验及全国31个地区按科技水平分类的研究,表明了该方法的可行性和有效性。 This paper proposed a method to get the optimal cluster number of FCM in real systems.Preset some reasonable cluster numbers,and then chose a cluster number as the optimal cluster number by some representative validity functions.Testing on the X30 and Bensaid data sets demonstrates the effectiveness and reliability of the proposed method.And finally gave an experiment on China's 31 regions according to the level of science and technology(ST) progress.
