Analysis And Research Of Graduate Students' State Based On Stochastic Matrix Theory L

The sustained and healthy growth of the people has always been an important symbol of the prosperity and strength of a country.In the"healthy China Action(2019-2030)",the National Health Commission clearly defined "personal regular records of physical and mental-health" as one of the main indicators of this action.In traditional Chinese medicine,pulse diagnosis has a special and very important position.This painless,non-invasive and easy to operate diagnosis method has 'been widely concerned by Chinese and foreign industries and research scholars in recent years.However,due to the lack of medical resources caused by pulse diagnosis relying on doctors' experience,it can not be popularized quickly and widely.By analyzing and discussing the research status of the objectification of pulse diagnosis,this paper uses random matrix theory to analyze pulse data,and constructs a method and system for evaluating human physical and mental health based on random matrix theory.The main advantage of random matrix theory is that it can analyze the energy spectrum of complex systems and obtain the random degree of data and the overall correlation characteristics of data.In this paper,the pulse data is analyzed based on the random matrix theory,and the detection model is constructed.It mainly includes the following parts:1.Active and passive data acquisition.Based on EOX oximeter,the fingertip pulse data of 61 graduate volunteers were collected and asked to complete the questionnaire.2.Pulse data preprocessing.After comparison and analysis,the precision parameter is set to 100.The baseline drift of pulse data is preprocessed.Intercept the data of 1500 points before and after the test to eliminate the impact of test jitter.3.Cut the pulse data by matrix.The matrix is cut according to the specification of 30mm 500 to prepare for the follow-up calculation.4.The matrix after cutting and transformation is analyzed by using the single loop theorem of random matrix,and the index of average spectral radius is obtained.According to the average spectral radius of pulse of each volunteer,the index is compared and analyzed,so as to achieve the effect of recognition.Through the experimental calculation and analysis,the results are obtained:when the body is out of order and the mind is out of order,that is,when the result of the questionnaire is in the third state,the average spectral radius of the pulse data is the smallest after being processed by the random matrix single ring theorem.When the body is in orderly mental balance,that is,when the result of the questionnaire is in the first state,after the pulse data are processed by the random matrix single ring theorem,the average spectral radius is the largest,and in the other two states,when the body is out of order and the mental balance is out of order and the body is out of order,the average spectral radius is distributed between the two.
