Abstract: This paper presents one clustering discrimination method which is different from the previous methods.It starts with the categories,constructs core-sets for clustering discrimination,and establishes a model to it.This paper uses the smallest circle as the core-sets for clustering discrimination in the 2-dimensional space and does numerical experiment on the diagnosis of breast cancer.In this model,this paper first selects the indicators,processes the data,and then takes the smallest circle as core-sets to establish the model,at last tests another 69 data.The rate of the misjudgment is 4.35%.
Key words: core-sets, centre of clustering, clustering discrimination
摘要: 区别于传统的聚类方法,提出了以类为起点,通过构造闭包进行聚类的新方法,并建立了聚类判别模型,此模型给出了对于闭包间的交叉区域的检验点的判别准则。然后针对二维的聚类问题,提出了以最小圆为闭包的聚类判别模型,并对乳房肿瘤病例进行数值实验。对于乳房肿瘤病例,首先进行了指标选取、数据预处理,然后以最小圆为闭包建立了模型,最后对69个待检测数据进行检验,结果误判率为4.35%。
