Machine Learning Based Method for Insurance Fraud Detection on Class Imbalance Datasets With Missing Values

Abstract

Insurance fraud is a prevalent issue that insurance companies must face, particularly in the realm of automobile insurance. This type of fraud has significant cost implications for insurance firms and can have a long-term impact on pricing strategies and insurance rates. As a result, accurately predicting and detecting insurance fraud has become a crucial challenge for insurers. The fraud datasets are usually imbalanced, as the number of fraudulent instances is much less than the ligament instances and contains missing values. Prior research has employed machine learning methods to address this class imbalance dataset problem, but there is limited effort handling the class imbalance dataset ..
