Abstract

Credit card defaults are among the most significant risks in the financial world, with the potential to negatively impact the overall financial health of the entire economy. Enhancing the accuracy of predicting and identifying credit defaults is essential in mitigating credit losses and minimizing financial risks in credit risk management. This research specifically focuses on the prediction of credit card defaults by comparing various traditional machine learning models. More importantly, it proposes a novel hybrid framework that integrates convolutional neural networks, long short-term memory, and attention mechanisms. By incorporating time-series components into our hybrid model, we achieved a notable improvement in predictive accuracy, outperforming the best traditional model by 16%. This study highlights the significant benefits of integrating temporal sequences into credit risk models, as it can greatly enhance the precision, reliability, and overall performance of credit card default predictions, offering important advantages for improving long-term financial stability and reducing associated risks.
