Abstract: Early claims in the life insurance sector can lead to significant financial losses if not properly managed. This paper experiments a number of feature selection such as values regrouping, over or undersampling, and encoding that aim to enhance early claim detection by considering five (5) different machine learning algorithms. Utilizing the built-in feature importance from Random Forest, along with regrouping and correlation techniques, we identify the top seven (7) most significant features from a total 800 feature candidates. Our proposed strategy provides a streamlined and effective way to focus on the most relevant features, thereby improving the accuracy and precision of early claim predictive models for the life insurance domain. The results of this study offer practical insights into reducing fraudulent claims and mitigating financial risk. We used Random Forest besides considering techniques such as LightGBM, XGBoost, Feed Forward Neural Network, and CatBoost to train our model and achieved a maximum accuracy of 0.92 across three samples, indicating that our approach can effectively identify critical features and produce reliable results.
