A physique recognition method based on feature selection and a classification model

Abstract

The invention discloses a physique recognition method based on feature selection and a classification model. The physique recognition method comprises the steps: generating answers of all questions ina'traditional Chinese medicine physique classification and judgment table ' through a random number generation algorithm; Calculating a corresponding physique type under the current answer accordingto a judgment method and a judgment standard of the traditional Chinese medicine physique classification and judgment table; adopting a feature selection algorithm to select a representative part of questions from all the questions of the'traditional Chinese medicine constitution classification and judgment table '; Designing a classification model, and performing training by utilizing answers ofpart of questions and corresponding physique types to obtain a physique recognition model; According to the method, technologies such as a random number generation algorithm, a feature selection algorithm and a classification model are introduced, the diagnosis time is effectively shortened, the diagnosis efficiency is improved, the effectiveness of physique recognition is ensured, and certain market value and popularization value are achieved.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a constitution recognition method based on feature selection and classification models. Background technique [0002] Human body constitution is a combination of morphological structure, physiological function, psychological state and other aspects that are manifested on the basis of congenital inheritance and acquired. Professor Wang Qi divides the constitution into nine constitution types: peace constitution, qi-deficiency constitution, yang-deficiency constitution, yin-deficiency constitution, phlegm-dampness constitution, damp-heat constitution, blood stasis constitution, qi stagnation constitution, and special endowment constitution [Wang Qi.
