[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein.
[0034] It should be understood that in various embodiments of the present invention, the size of the sequence number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0038] Depending on the context, "if" as used herein may be interpreted as "when" or "when" or "in response to determining" or "in response to detecting."
[0039] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0040] The present invention provides an insurance recommendation evaluation method applicable to assisted reproductive insurance, such as Figure 1 The flow chart shown includes:
[0041] S10, receiving the index data input by the applicant for reproductive insurance, wherein the index data includes any one or more of the physical examination result information and the physiological characteristic information, wherein the physical examination result information and the physiological characteristic information respectively include age, ovarian reserve (AMH, AFC, FSH, etc.), body mass index BMI, six hormones, semen analysis, duration of infertility, previous live births, previous miscarriages and infertility type, etc.
[0042] S20. Process the indicator data based on a preset prediction model to generate an insurance recommendation result, wherein the prediction model is pre-trained and generated.
[0043] In one embodiment, Figure 2 As shown, the indicator data is processed based on a preset prediction model to generate an insurance recommendation result, wherein the prediction model is pre-trained and generated including:
[0044] S201, obtaining a preset number of samples in a database as a training sample set;
[0045] S202, based on a preset algorithm, taking the number of pregnancies of each couple through assisted reproduction as a prediction target, and the original variables or derived variables after cleaning the training sample set as a training feature set, to obtain a correlation function between the prediction target and the training feature set;
[0046] S203: Optimize the correlation function between the prediction target and the training feature set to obtain a final parameter set.
[0047] In the above steps, after data processing, 70% of the data set is randomly selected as a training set to build a prediction model, and the remaining 30% is used for validation. A variety of supervised machine learning algorithms are used to construct the main components of the prediction model / supplemented model to facilitate the subsequent reference of logistic regression and stratified random sampling, including logistic regression, random forest, and catboost. Although the above three algorithms have their own advantages and disadvantages, they all have interpretable properties. The calculation process can be repeated ("simulatability") with a full understanding of the algorithm, and each part of the model has an intuitive explanation ("algorithm transparency"). The prediction model takes the number of assisted reproductive cycles each couple needs to get pregnant as the prediction target, and the cleaned original variables or derived variables are used as the training feature set. The interaction relationship between the training features is mined, and the final parameter set is obtained by optimizing the objective function.
[0048] Furthermore, the prediction model is pre-trained and generated based on a stratified random sampling method.
[0049] Furthermore, the optimal hyperparameters of the prediction model are determined based on a grid search with K-fold cross-validation to obtain the hyperparameter set that maximizes the average accuracy;
[0050] The prediction models are fitted to the entire training data set respectively.
[0051] The training process of the prediction model adopts a stratified random sampling method to ensure that the proportion of live births and non-live births in the training set and the validation set is the same as that in the original data set. The optimal hyperparameters of the algorithm are selected by a grid search with K-fold cross-validation, and finally the hyperparameter set with the maximum average accuracy is obtained, and the model is fitted to the entire training data set respectively. Finally, the present invention evaluates the receiver operating characteristic (ROC) curve to select the final model.
[0052] Since the present invention is used for risk assessment of assisted reproductive insurance before entering the cycle, such as Figure 3 As shown, the present invention can therefore only use clinical data obtained before starting the IVF procedure.
[0053] The present invention trains and develops artificial intelligence algorithms based on a large amount of health physiological and clinical data, and verifies the algorithms with reserved data other than training data. The risk attributes of applicants for assisted reproductive insurance are evaluated when the applicants provide some physical examination results and physiological characteristics. By identifying adverse events covered by insurance and speeding up the application and underwriting process, effective solutions are provided for insurance companies in the fields of insurance consulting, application process, underwriting process and risk management, enabling them to provide customers with high-quality and affordable assisted reproductive protection and health management services.
[0054] In the initial data for model training, anonymous data of more than 100,000 couples recorded by the Human Fertilization and Embryology Authority (HFEA), which is responsible for regulating fertility treatment in the UK, was used. Anonymous data is the registration data that includes most of the data since 1991 after the patient's identity information is hidden. Anonymous data without identification codes protects patient privacy by grading or hiding some information. Scientific research using anonymous data can still answer important questions. Such as which factors (patients, types of treatments, and technologies used) can affect treatment outcomes, or which indicators suggest that patients only need to implant one or two embryos during treatment. This information covers cycles from January 1, 1991 to March 31, 2009. This data set contains about 90 variables. Not all variables have a significant predictive effect on live births. Under the guidance of reproductive medical experts, the present invention cleans and corrects the data again and clearly defines and standardizes the variables to reproduce candidate predictive variables.
[0055] In addition, contradictory data points in the original data are eliminated, such as the use of frozen embryos in the later stage without a previous history of pregnancy and childbirth; the original variables are used to generate derived variables, such as weight and height to calculate the body mass index (BMI), and classify and label them; the causes of infertility and reproductive medical experts are classified and scored, etc.
[0056] In the above initial training and verification process, by evaluating the importance of parameter features to the final prediction results, multiple relevant variables of both men and women before entering the assisted reproductive week were extracted, such as age, ovarian reserve (AMH, AFC, FSH, etc.), body mass index BMI, six hormones, semen analysis, duration of infertility, previous live births, previous miscarriages and infertility types, etc., and the applicants need to do several IVF cycles for successful pregnancy to predict. Combine the prediction results and perform feature importance ranking through retrospective analysis to find the most relevant features of the applicants to finally evaluate the risk attributes of the applicants for assisted reproductive insurance: extremely high risk, high risk, moderate risk, medium-low risk and low risk. / Classification name to add risk attributes /
[0057] After determining the final prediction of the risk assessment of assisted reproductive insurance, the final first-generation underwriting engine is obtained by fitting the entire training data. In addition, it participates in the domestic assisted reproductive "good pregnancy insurance" insurance business, and uses data from multiple reproductive medical centers for verification and iteration.
[0058] A second aspect of an embodiment of the present invention provides an insurance recommendation evaluation device applicable to assisted reproductive insurance, such as Figure 4 As shown, including:

[0064] The correlation function between the prediction target and the training feature set is optimized to obtain a final parameter set.
[0065] Furthermore, the prediction model is pre-trained and generated based on a stratified random sampling method.
[0066] Furthermore, the optimal hyperparameters of the prediction model are determined based on a grid search with K-fold cross-validation to obtain the hyperparameter set that maximizes the average accuracy;
[0067] The prediction models are fitted to the entire training data set respectively.

The communication medium includes any medium that facilitates the transmission of a computer program from one place to another. The computer storage medium can be any available medium that can be accessed by a general-purpose or special-purpose computer.
