Results indicate that an artificial NN underwriting model outperformed a linear model and a logistic model. Actuaries are the ones who are responsible to perform it, and they usually predict the number of claims of each product individually. history Version 2 of 2. In health insurance many factors such as pre-existing body condition, family medical history, Body Mass Index (BMI), marital status, location, past insurances etc affects the amount. A building without a fence had a slightly higher chance of claiming as compared to a building with a fence. Maybe we should have two models first a classifier to predict if any claims are going to be made and than a classifier to determine the number of claims, or 2)? i.e. The main aim of this project is to predict the insurance claim by each user that was billed by a health insurance company in Python using scikit-learn. To demonstrate this, NARX model (nonlinear autoregressive network having exogenous inputs), is a recurrent dynamic network was tested and compared against feed forward artificial neural network. Children attribute had almost no effect on the prediction, therefore this attribute was removed from the input to the regression model to support better computation in less time. (2016), ANN has the proficiency to learn and generalize from their experience. In fact, the term model selection often refers to both of these processes, as, in many cases, various models were tried first and best performing model (with the best performing parameter settings for each model) was selected. It was observed that a persons age and smoking status affects the prediction most in every algorithm applied. Users can develop insurance claims prediction models with the help of intuitive model visualization tools. You signed in with another tab or window. A key challenge for the insurance industry is to charge each customer an appropriate premium for the risk they represent. arrow_right_alt. Decision on the numerical target is represented by leaf node. (2013) and Majhi (2018) on recurrent neural networks (RNNs) have also demonstrated that it is an improved forecasting model for time series. DATASET USED The primary source of data for this project was . Previous research investigated the use of artificial neural networks (NNs) to develop models as aids to the insurance underwriter when determining acceptability and price on insurance policies. Various factors were used and their effect on predicted amount was examined. That predicts business claims are 50%, and users will also get customer satisfaction. (2016) emphasize that the idea behind forecasting is previous know and observed information together with model outputs will be very useful in predicting future values. The mean and median work well with continuous variables while the Mode works well with categorical variables. In the next part of this blog well finally get to the modeling process! arrow_right_alt. Also with the characteristics we have to identify if the person will make a health insurance claim. 2 shows various machine learning types along with their properties. Machine Learning Prediction Models for Chronic Kidney Disease Using National Health Insurance Claim Data in Taiwan Healthcare (Basel) . Predicting the Insurance premium /Charges is a major business metric for most of the Insurance based companies. The models can be applied to the data collected in coming years to predict the premium. Logs. REFERENCES Once training data is in a suitable form to feed to the model, the training and testing phase of the model can proceed. Test data that has not been labeled, classified or categorized helps the algorithm to learn from it. Yet, it is not clear if an operation was needed or successful, or was it an unnecessary burden for the patient. In this learning, algorithms take a set of data that contains only inputs, and find structure in the data, like grouping or clustering of data points. The ability to predict a correct claim amount has a significant impact on insurer's management decisions and financial statements. This can help a person in focusing more on the health aspect of an insurance rather than the futile part. According to Rizal et al. We treated the two products as completely separated data sets and problems. Removing such attributes not only help in improving accuracy but also the overall performance and speed. Several factors determine the cost of claims based on health factors like BMI, age, smoker, health conditions and others. This is the field you are asked to predict in the test set. The data was in structured format and was stores in a csv file format. "Health Insurance Claim Prediction Using Artificial Neural Networks.". Data. by admin | Jul 6, 2022 | blog | 0 comments, In this 2-part blog post well try to give you a taste of one of our recently completed POC demonstrating the advantages of using Machine Learning (read here) to predict the future number of claims in two different health insurance product. It would be interesting to see how deep learning models would perform against the classic ensemble methods. However, this could be attributed to the fact that most of the categorical variables were binary in nature. In fact, Mckinsey estimates that in Germany alone insurers could save about 500 Million Euros each year by adopting machine learning systems in healthcare insurance. A tag already exists with the provided branch name. In I. Later they can comply with any health insurance company and their schemes & benefits keeping in mind the predicted amount from our project. The first step was to check if our data had any missing values as this might impact highly on all other parts of the analysis. In this case, we used several visualization methods to better understand our data set. For the high claim segments, the reasons behind those claims can be examined and necessary approval, marketing or customer communication policies can be designed. Approach : Pre . Supervised learning algorithms learn from a model containing function that can be used to predict the output from the new inputs through iterative optimization of an objective function. Health Insurance Cost Predicition. Our project does not give the exact amount required for any health insurance company but gives enough idea about the amount associated with an individual for his/her own health insurance. The network was trained using immediate past 12 years of medical yearly claims data. Abhigna et al. It is based on a knowledge based challenge posted on the Zindi platform based on the Olusola Insurance Company. Insurance companies apply numerous techniques for analysing and predicting health insurance costs. All Rights Reserved. Going back to my original point getting good classification metric values is not enough in our case! Accurate prediction gives a chance to reduce financial loss for the company. As a result, we have given a demo of dashboards for reference; you will be confident in incurred loss and claim status as a predicted model. Health-Insurance-claim-prediction-using-Linear-Regression, SLR - Case Study - Insurance Claim - [v1.6 - 13052020].ipynb. Currently utilizing existing or traditional methods of forecasting with variance. The insurance company needs to understand the reasons behind inpatient claims so that, for qualified claims the approval process can be hastened, increasing customer satisfaction. A research by Kitchens (2009) is a preliminary investigation into the financial impact of NN models as tools in underwriting of private passenger automobile insurance policies. The network was trained using immediate past 12 years of medical yearly claims data. thats without even mentioning the fact that health claim rates tend to be relatively low and usually range between 1% to 10%,) it is not surprising that predicting the number of health insurance claims in a specific year can be a complicated task. 4 shows the graphs of every single attribute taken as input to the gradient boosting regression model. Neural networks can be distinguished into distinct types based on the architecture. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. An increase in medical claims will directly increase the total expenditure of the company thus affects the profit margin. Whats happening in the mathematical model is each training dataset is represented by an array or vector, known as a feature vector. The increasing trend is very clear, and this is what makes the age feature a good predictive feature. Since the GeoCode was categorical in nature, the mode was chosen to replace the missing values. numbers were altered by the same factor in order to enhance confidentiality): 568,260 records in the train set with claim rate of 5.26%. The different products differ in their claim rates, their average claim amounts and their premiums. (2022). (2011) and El-said et al. In the insurance business, two things are considered when analysing losses: frequency of loss and severity of loss. Using a series of machine learning algorithms, this study provides a computational intelligence approach for predicting healthcare insurance costs. Dataset was used for training the models and that training helped to come up with some predictions. Training data has one or more inputs and a desired output, called as a supervisory signal. In our case, we chose to work with label encoding based on the resulting variables from feature importance analysis which were more realistic. Results indicate that an artificial NN underwriting model outperformed a linear model and a logistic model. Regression or classification models in decision tree regression builds in the form of a tree structure. The website provides with a variety of data and the data used for the project is an insurance amount data. Health insurers offer coverage and policies for various products, such as ambulatory, surgery, personal accidents, severe illness, transplants and much more. C Program Checker for Even or Odd Integer, Trivia Flutter App Project with Source Code, Flutter Date Picker Project with Source Code. (2020) proposed artificial neural network is commonly utilized by organizations for forecasting bankruptcy, customer churning, stock price forecasting and in many other applications and areas. Factors determining the amount of insurance vary from company to company. Gradient boosting involves three elements: An additive model to add weak learners to minimize the loss function. This amount needs to be included in Though unsupervised learning, encompasses other domains involving summarizing and explaining data features also. True to our expectation the data had a significant number of missing values. This can help not only people but also insurance companies to work in tandem for better and more health centric insurance amount. ). (2020) proposed artificial neural network is commonly utilized by organizations for forecasting bankruptcy, customer churning, stock price forecasting and in many other applications and areas. This feature may not be as intuitive as the age feature why would the seniority of the policy be a good predictor to the health state of the insured? Accuracy defines the degree of correctness of the predicted value of the insurance amount. The distribution of number of claims is: Both data sets have over 25 potential features. We found out that while they do have many differences and should not be modeled together they also have enough similarities such that the best methodology for the Surgery analysis was also the best for the Ambulatory insurance. insurance claim prediction machine learning. Also it can provide an idea about gaining extra benefits from the health insurance. By filtering and various machine learning models accuracy can be improved.
