Abstract

Credit default risk assessment is a critical task in the financial sector, enabling lenders to evaluate borrower reliability and minimise financial losses. Traditional statistical models, such as logistic regression, often struggle to capture complex nonlinear relationships within high-dimensional financial datasets. Recent advancements in machine learning, particularly ensemble learning techniques, have demonstrated improved predictive performance and robustness in credit risk modelling. This paper presents an ensemble learning-based framework for predicting credit default risk using structured financial and behavioural data. The proposed system integrates feature engineering, class imbalance handling, and multiple ensemble algorithms, including Random Forest, Gradient Boosting, and Extreme Gradient Boosting. Experimental evaluation demonstrates improved accuracy, recall, and Area Under the ROC Curve compared to single-model baselines. The framework provides a scalable and reliable solution for financial risk management systems.

Full Article/Conclusion

This paper presented an ensemble learning- based framework for predictive modelling of credit default risk. The proposed system achieves improved predictive accuracy and robustness compared to traditional models.   Future work includes integrating deep neural ensemble architectures, incorporating real-time transaction data for dynamic credit scoring, implementing federated learning for privacy- preserving financial modelling, and enhancing explainability for regulatory transparency. This proctoring is 90% accuracy.
