Detecting Automobile Insurance Fraud Using a Novel Penalty-Driven Feature Selection Method with Particle Swarm Optimization and Machine Learning Classifiers
This study proposes a novel penalty-driven feature selection method with particle swarm optimization (PDFS-PSO) for detecting automobile insurance fraud. It addresses challenges of high-dimensional, imbalanced data and limited interpretability in traditional machine learning approaches. Evaluated on the 'Angoss carclaims' dataset, the method achieved 97.55% accuracy with a balanced F1-score of 0.9754 using a stacking classifier and reducing features to 16, demonstrating effective balance between predictive accuracy and interpretability.
Quantifiable Business Impact
Automobile insurance fraud costs billions annually. Implementing AI-driven fraud detection can significantly reduce these losses, optimize operational efficiency, and maintain customer trust. Our approach focuses on highly accurate and interpretable models to ensure practical utility for insurers.

Case Study: Credit Card Fraud Dataset Validation
The PDFS-PSO method was externally validated on an imbalanced credit card fraud dataset. It achieved 0.998 accuracy, 0.901 recall, and 0.688 MCC, demonstrating strong cross-domain applicability and robustness even with extreme class imbalance. This suggests the framework can generalize beyond automobile insurance.
