基于灰色关联分析法的阳虚质影响因子分析
Grey correlation analysis on influencing factors of Yang deficiency constitution
摘要
Abstract
Objective To explore the influencing factors of Yang deficiency constitution in traditional Chinese medicine(TCM)from the perspective of mathematics with the use of calculation for-mulas,so as to protect patients from getting diseases caused by Yang deficiency constitution and provide suggestions for TCM disease prevention.Methods Based on the classification and determination criteria of TCM constitution imple-mented by China Association of Chinese Medicine,data for 24 solar terms from May 5,2020(Start of Summer)to April 20,2021(Grain Rain)for the identification of Yang deficiency were collected by mobile constitution identification system.The grey correlation analysis method was used to determine the grey correlation degree of the factors influencing Yang deficiency constitution.In addition,a random forest model was constructed for the verification of the results from the grey correlation analysis,and for the evaluation of correlation degree between Yang deficiency constitution and its influencing factors.Results A total of 16 259 sets of data were collected from healthy or sub-healthy individuals aged from 18 to 60 years living in the central and northeastern parts of Sichuan Province(China)for the identification of TCM constitutions.After screening and preprocessing,a total of 544 sets of data for the identification of Yang deficiency constitution,involving 18 aspects of factors influencing Yang deficiency constitution.The results of the grey correlation analysis showed that there were 12 influencing factors whose grey correlation degree with Yang defi-ciency constitution was greater than 0.6.The accuracy of these 12 influencing factors with the training set and validation set of the Yang deficiency constitution random forest model were 98.39%and 93.12%,respectively.Conclusion In the sample data selected in this paper,grey correlation analysis is the appro-priate technology to analyze the influencing factors of Yang deficiency constitution.It provides a new idea and a new methodological reference for the research and analysis of the influencing factors of TCM constitution.关键词
