【摘要】 目的:提出一种应用光谱法来反映舌部信息的方法,最终达到将中医证型客观化的目的。方法:使用光谱仪采集舌部的光谱数据,再通过偏最小二乘和支持向量机的方法,找出光谱数据与中医证型之间的联系,从而实现中医证型客观化。结果:实验用可见光光谱,对采集到的53例表寒里热证患者、37例健康人作分析,分别使用支持向量机和偏最小二乘的方法对数据进行分类和预测,两种方法都可以100%正确地将两类数据区分开,但从预测精度上来讲,支持向量机的预测误差平方均值为0.07734,要优于偏最小二乘的0.13539,所以支持向量机的方法用于可见光光谱的分类要更优一些。结论:提出了中医舌诊的客观化的一种全新研究思路,并为进行中医症候的分类打下基础。更多还原

【Abstract】 Objective: This paper puts forward a method to observe the information the tongue carrying using spectrometry,finally achieve the goal of externalization of application of syndrome differentiation.Methods: This paper collected spectrum data by instrumental means,and seek for association between spectrum data and syndrome differentiation,so that achieve externalization of application of syndrome differentiation.Results: In the experiment,we used visible spectra and collected 53 exterior cold and interior heat patients,37 healthy samples.For data modeling,used partial least square(PLS) and support vector machine(SVM),both of the method can predict the two sorts of data perfectly with 100%,but considering mean squared error(MSE),MSE of SVM was 0.07734 which was better than PLS’s 0.13539.So SVM is a better way to modeling spectrum data.Conclusion: This paper provides a whole new research method of the tongue objectivation of traditional Chinese medicine,and lay the foundation for the classification of traditional Chinese medicine symptoms.更多还原
