[0020] Based on the subtraction result, the influence degree of the corresponding element combination and the vulnerability index is calculated, and the combination is screened to obtain the environmental label.
[0021] The calculation formula of the impact degree is as follows:
[0022]
[0023] in, Indicates the difference between the data before and after the operation in the nth row and jth column of the subtraction result, N represents the total number of rows, and B j Indicates the impact degree of the corresponding vulnerability indicator.

[0039] A correction compensation is introduced to correct the similarity of the data points for each category.
[0040] Through this preferred step, different types of corrections are considered and used to correct the final result, which helps to obtain a more accurate matching classification, including age correction, gender correction and BMI correction.

[0062] Reference Figure 1 , is a flow chart of an optional example of a method for regional user health risk assessment proposed by the present invention, which method can be applied to a computer device. The imaging method proposed in this embodiment may include but is not limited to the following steps:
[0063] Step S1, obtaining physical examination data and collating vulnerability indicators;
[0064] Step S2, obtaining regional environmental data and constructing element combinations;
[0065] Step S3: Associating the vulnerability indicator with the element combination to obtain an environmental label;
[0066] Step S4, associating the vulnerability index with the living habits to obtain a relationship network;
[0067] Step S5: Based on the relationship network, classify the vulnerability indicators and living habits to obtain a data pool;
[0068] Step S6: Obtain the environmental label corresponding to the user to be tested and combine it with the actual living habits as input, match it with the data pool, and obtain the health risk assessment result.
[0069] In some feasible embodiments, the step S1 specifically includes:
[0070] Convert physical examination data into corresponding frailty indicators;
[0071] Vulnerability indicators: 1. Hypertension; 2. Heart disease; 3. Stroke; 4. Neurasthenia; 5. Peptic ulcer; 6. Cholecystitis; 7. Diabetes; 8. Bronchitis; 9. Emphysema; 10. Chronic kidney disease; 11. Cancer; 12. Asthma; 13. Chest tightness / dyspnea; 14. Gastroenteritis; 15. COPD; 16. Prostatitis; 17. Rhinitis; 18. Liver disease; 19. Hyperlipidemia; 20. Tuberculosis; 21. BMI; 22. WHR; 23. Whether the electrocardiogram is abnormal; 24. Whether the chest X-ray is abnormal; 25. Pancreatic disease; 26. Coronary heart disease; 27. Thyroid disease; 28. Stomach disease.
[0072] In this embodiment, there are 28 types of personal vulnerability indicators A=[T 1 ,T 2 ,T 3 ,......,T 28 ], each vulnerability indicator is associated with a specific disease, among which T i (i=1,2,3,...,28) the value is:
[0073]
[0074] In personal physical examination data, specific numerical values can usually be obtained. After being judged by doctors or professional instruments, these numerical values can be converted into binary values, that is, 1 or 0.
[0075] In some feasible embodiments, the step S2 specifically includes:
[0076] S2.1. The regional environmental data include atmospheric particulate metal concentrations, drinking water metal concentrations and soil metal concentrations;
[0077] The regional environmental data measured by relevant instruments mainly include atmospheric particulate metal concentration (M 1 ), drinking water metal concentration (M 2), soil metal concentration (M 3 )+three major categories. Each category contains 16 chemical elements, including V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Mo, Cd, Sn, Sb, Tl, and Pb. Therefore, three environmental data matrices can be obtained:
[0078] M 1 =[m 1 ,m 2 ,m 3 ,...,m 16 ]
[0079] M 2 =[m 1 ,m 2 ,m 3 ,...,m 16 ]
[0080] M 3 =[m 1 ,m 2 ,m 3 ,...,m 16 ]
[0081] Where m t , t=1,..,16 are the specific values of the concentrations of different chemical elements in the measured environment.
[0082] S2.2. Taking a preset number of chemical elements from the environmental data of different categories to construct an element combination.
[0083] On this basis, in M 1 、M 2 、M 3 Take one chemical element from each as a combination (total method).
[0084] The subsequent determination is used to determine the value of each combination pair A=[T 1 ,T 2 ,T 3 ,......,T 28 ] was used to determine which indicator had the most significant impact (i.e., the greatest importance). Finally, 28 combinations were selected, each corresponding to a personal vulnerability indicator.
[0085] In some feasible embodiments, the step S3 specifically includes:
[0086] S3.1, merging the regional environmental data to obtain a first environmental matrix;
[0087] First, M 1 、M 2 、M 3Merge into a matrix M:
[0088]
[0089] in Respectively represent M 1 、M 2 、M 3 The corresponding data.
[0090] S3.2, combining the physical examination data and the fragility index to obtain a first index matrix;
[0091] A 1 To A n Merge into a matrix A:
[0092]
[0093] in It represents the value of the nth row and jth column, corresponding to the sequence number of the person and the sequence number of the vulnerability indicator.
[0094] S3.3, based on the first environment matrix and the first indicator matrix, using machine learning to establish a relationship model;
[0095] Use machine learning technology to establish a relationship network between environmental data and personal vulnerability indicators, and obtain the relevant training model N, where A n Represents the overall vulnerability index data of the nth person:
[0096] S3.4, shuffling the first environment matrix to obtain a second environment matrix;
[0097] M' is obtained by randomly shuffling the data in the tth (t=1, 2, 3, ..., 16) column of M up and down (shuffling horizontally will give various combinations).
[0098] S3.5, inputting the second environment matrix into the relationship model to obtain a second indicator matrix;
[0099] Input M' into the previously obtained model N to obtain the new A'.
[0100] S3.6. Subtract the second indicator matrix from the first indicator matrix to obtain a subtraction result;
[0101] The subtraction calculation is expressed as follows:
[0102] D = A'-A;
[0103]
[0104] in Represents the difference between the data before and after the operation on the nth row and jth column.
[0105] S3.7. Based on the subtraction result, calculate the influence degree of the corresponding element combination and the vulnerability index, screen the combination, and obtain the environmental label.
[0106] Then calculate To represent chemical element combinations The impact degree of the jth vulnerability indicator is finally compared with 28 B j Get the maximum value B j , which can represent the combination of chemical elements The jth vulnerable indicator has the greatest impact, and the combination The corresponding j-th vulnerability indicator bundle is defined as the environmental label E j .
[0107] In some feasible embodiments, the step S4 specifically includes:
[0108] Establish a personal vulnerability index A = [T 1 ,T 2 ,T 3 ,......,T 28 ] and the relationship network W of corresponding living habits.
[0109] Among them, living habits can be learned from questionnaires, and the questionnaire options (such as smoking frequency, sleep quality, etc.) can be quantified into life characteristics K = (d 1 ,d 2 ,d 3 ,...,d n )(n∈N + ));
[0110] The personal vulnerability index values in physical examination data often correspond to the individual's living habits, and it has been medically proven that there is a significant correlation between the two. A person's unhealthy living habits are often the factors that lead to his or her illness.
[0111] In some feasible embodiments, the step S5 specifically includes:
[0112] The 28 personal vulnerability indicators are divided into four categories (7 items in each category): high risk R1, medium-high risk R2, medium-low risk R3, and low risk R4. Combined with the relationship network W established above, life characteristics K = (d 1 ,d 2 ,d 3 ,...,d n )(n∈N + ) Following the individual vulnerability indicators, they are also divided into four corresponding categories, that is, four data pools V are established. 1 、V2 、V 3 、V 4 .
[0113] After completing the above steps, in order to determine the main categories to which the living habits belong, a model is used for analysis. The model can determine which category the living habits are most likely to belong to and classify them into the corresponding category. Then, based on the specific environmental labels corresponding to the user's environment, it is further determined which vulnerability indicator in this category is most likely to correspond. The system will recommend that users go to the hospital for targeted examinations to achieve health risk warning effects. The implementation of this process helps save users' time and money, while effectively avoiding the waste of hospital medical resources.
[0114] In some feasible embodiments, the step S6 specifically includes:
[0115] S6.1. Determine anchor points, positive samples, and negative samples according to the data pool;
[0116] Randomly select a sample from each data pool as the anchor point X ahr , and then randomly select another sample from the same data pool as the positive sample X pos , and then randomly select a sample from different data pools as a negative sample X neg .
[0117] S6.2, define twin network;
[0118] Design the structure of the twin network, which contains two identical sub-networks that share weight parameters.
[0119] S6.3, respectively inputting the positive sample and the negative sample into the twin network and generating a low-dimensional feature representation, and training them in combination with the anchor point to obtain a trained twin network;
[0120] The positive and negative samples input respectively eventually produce a low-dimensional representation, and the anchor points and loss functions are trained to obtain a trained twin network model.
[0121] In the twin network model, it is used as the ContrastiveLOSS loss function for calculation:
[0122]
[0123] Among them, Y represents the same category label:
[0124]
[0125] The above formula shows that the anchor point and the positive sample are in V i(i=1,2,3,4) The same data pool takes 1, and the anchor point and negative sample are in the same data pool V i (i=1,2,3,4) then take 0.
[0126] D represents the low-dimensional representation of samples and anchor points F(X) and F(X ahr ), the following is calculated using the Mahalanobis distance:
[0127]
[0128] Among them, ∑ -1 is the covariance matrix N is the size of the data pool, X k is the kth data point in the data pool, and μ is the inverse matrix of the mean vector of the data pool.
[0129] m represents the edge threshold in ContrastiveLOSS and is a predetermined hyperparameter.
[0130] S6.4. Processing the data pool based on a clustering algorithm to obtain corresponding category center points;
[0131] Using clustering algorithm, we get four data pools V 1 、V 2 、V 3 、V 4 The corresponding four category center points C i (i=1,2,3,4).
[0132] S6.5, obtain the environment label corresponding to the user to be tested and construct data points based on actual living habits;
[0133] S6.6, inputting the data points into the trained twin network to obtain a low-dimensional representation to be tested;
[0134] At this time, for a new data point X new , input it into the trained twin network model to obtain the corresponding low-dimensional representation F(X new ), this low-dimensional representation is a data representation with good features obtained through network learning, which contains information about the input data X new Related important feature information can be used to calculate similarity
[0135] S6.7, calculating the cosine similarity between the low-dimensional representation to be tested and the center point of the category, and obtaining the similarity of the data point for each category;
[0136] The following uses cosine similarity to judge X new Which category does it belong to:
[0137]
[0138] Calculate the new data point X new For each category, the similarity S i (i=1,2,3,4).
[0139] S6.8. Obtain a health risk assessment result of the user to be tested based on the similarity of the data points for each category.
[0140] In this embodiment, a specific application scenario example is also given: the user fills in the living habits questionnaire in the system, and the system quantifies the user's living habits into specific numbers that can be recognized by the computer according to the relationship network W. In the first step, the user is preliminarily classified into high-risk R1 according to the quantified living habits characteristics; in the second step, the system obtains the environmental label of the user's region. There are 7 kinds of vulnerable indicators in the high-risk R1 (corresponding to 7 kinds of environmental labels respectively). The system determines the similarity between the user's environmental label (such as [V, Cr, Mn]) and each of the 7 environmental labels (the low-dimensional representation obtained by the twin network model and the cluster center point obtained by machine learning technology are used for similarity calculation), and 7 similarities are obtained and arranged from high to low to be displayed to the user. The vulnerable indicator corresponding to the environmental label with the largest similarity is taken (such as [V, Cr, Mn] has the largest similarity with [V, Cr, Fe], and [V, Cr, Fe] corresponds to chronic kidney disease), and the user is reminded to go to the hospital for examinations related to the vulnerable indicator (chronic kidney disease).
[0141] In some feasible embodiments, the step S6 further includes:
[0142] A correction compensation is introduced to correct the similarity of the data points for each category.
[0143] As age increases, the body's resistance will gradually decline, that is, the probability of illness will continue to increase, and women's resistance is slightly lower than that of men. At the same time, a person's BMI can also more intuitively reflect the strength of their resistance. Therefore, age, gender and BMI occupy an indispensable position in health risk assessment and early warning. For this reason, the present invention introduces the age correction amount P age , Gender correction supplement P gender , BMI correction supplement P bmi To obtain more accurate results, the introduction process is as follows:
[0144] The age correction is defined as follows:
[0145]
[0146] Where α is the age coefficient, which is set by the expert’s prior knowledge; X age is the age of the new data point (0-100 years old); Xstd is the base age, the most obvious turning point of personal physical changes announced by the National Health Commission, i.e. 35 years old; σ is the standard deviation of the Gaussian distribution of the population age.
[0147] The following formula defines the gender correction amount:
[0148] P gender =β·X gender
[0149] Where β is the weak coefficient of gender, which is set after further weakening the expert’s prior knowledge; X gender Gender is a binary quantity:
[0150]
[0151] The following formula defines the BMI correction amount:
[0152]
[0153] Among them, γ, a, and b are BMI strength coefficients, which are set after further strengthening the prior knowledge of experts; X bmi is the BMI value of the new data point.
[0154] At the same time, we further define the interaction compensation I 1 ,I 2 :
[0155] I 1 =P age ·P bmi
[0156]
[0157] From the above, we can get the final correction compensation P final The definition is as follows:
[0158]
[0159] Therefore, a more accurate new data point X can be obtained. new The corresponding membership degree of each category
[0160] Affiliation i (i=1,2,3,4):
[0161] Affiliation i =max i (S i -P final )
[0162] Finally, the category with the highest membership is selected as the new data point X newclassification or corresponding results.
[0163] Based on the above health risk assessment results, targeted early warnings are implemented to optimize users' time and money costs and avoid unnecessary waste of medical resources.
[0164] like Figure 2 As shown, a regional user health risk assessment system includes:
[0165] A first data sorting module is used to obtain physical examination data and sort out vulnerability indicators;
[0166] The second data sorting module is used to obtain regional environmental data and construct element combinations;
