近年来,支持向量机(SVM)在分类和预测方面具有优异的性能,被广泛应用于疾病诊断和医疗辅助等领域。然而,SVM只适用于两组分类问题。本研究结合特徴选择与支持向量机递归特徴消除(SVM-RFE),探讨皮肤科与动物园资料库多类别问题的分类准确度。皮肤病学数据集包含33个特征变量,1个类变量和366个测试实例; Zoo数据集包含16个特征变量,1个类变量和101个测试实例。两个数据集中的特征变量按解释力从高到低排序,并通过SVM-RFE选择不同的特征集来探索分类精度。同时,将田口方法与SVM分类器相结合,优化参数C和γ,提高多类分类的分类精度。实验结果表明,在皮肤病学和动物园数据库的SVM-RFE特征选择和田口参数优化后,分类准确率可以达到95%以上。
Recently, support vector machine (SVM) has excellent performance on classification and prediction and is widely used on disease diagnosis or medical assistance. However, SVM only functions well on two-group classification problems. This study combines feature selection and SVM recursive feature elimination (SVM-RFE) to investigate the classification accuracy of multiclass problems for Dermatology and Zoo databases. Dermatology dataset contains 33 feature variables, 1 class variable, and 366 testing instances; and the Zoo dataset contains 16 feature variables, 1 class variable, and 101 testing instances. The feature variables in the two datasets were sorted in descending order by explanatory power, and different feature sets were selected by SVM-RFE to explore classification accuracy. Meanwhile, Taguchi method was jointly combined with SVM classifier in order to optimize parameters C and γ to increase classification accuracy for multiclass classification. The experimental results show that the classification accuracy can be more than 95% after SVM-RFE feature selection and Taguchi parameter optimization for Dermatology and Zoo databases.
