Abstract

The insurance industry has grown rapidly and is significantly playing an important role in the economy of a country. However, one lingering issue faced by insurers is being able to correctly predict if a policyholder will lay a claim so as to determine a fair price to be charged for purchasing an insurance policy. The goal of this research is to make a comparison between individual classifiers and ensemble techniques to determine which provides the best predictive results. The Knowledge Discovery in Database (KDD) process was adopted to gain insight and business knowledge from the dataset. Four individual classifiers, Support Vector Machine, Linear Discriminate Analysis, Logistic regression and Artificial Neural Network along with two ensemble techniques, Extreme Gradient boosting and stacking were used, the research discovered that the ensemble techniques used gave a better predictive result than all the selected individual classifiers. XGBoost had an accuracy of 96% while stacking algorithm had 76%. The performance metrics chosen for this research was accuracy, sensitivity and AUC.
Keywords: Insurance claim, Ensemble, Prediction, Stacking, Support Vector Machine, Linear Discriminate Analysis, Extreme Gradient Boosting, Logistic regression, Artificial Neural Network.
