基于粒子群优化算法的特征选择SVM分类
针对“BreastCancer”数据集,作为对比,第一次对特征集直接进行SVM分类,第二次使用粒子群算法进行特征选择后再进行SVM分类。并且对比和分析了两次分类的结果。(For "BreastCancer" data set, as a comparison, the first time the feature set is directly classified by SVM, and the second time the feature set is selected by particle swarm optimization before SVM classification. The results of the two classifications are compared and analyzed.)

Fuzzyclustering
模糊聚类;涉及事物之间的模糊界限时按一定要求对事物进行分类的数学方法。聚类分析是数理统计中的一种多元分析方法,它是用数学方法定量地确定样本的亲疏关系,从而客观地划分类型。事物之间的界限,有些是确切的,有些则是模糊的。例如人群中的面貌相像程度之间的界限是模糊的,天气阴、晴之间的界限也是模糊的。当聚类涉及事物之间的模糊界限时,需运用模糊聚类分析方法。模糊聚类分析广泛应用在气象预报、地质、农业、林业等方面。通常把被聚类的事物称为样本,将被聚类的一组事物称为样本集。模糊聚类分析有两种基本方法:系统聚类法和逐步聚类法。
