Consequently, global credit card companies, including banks and financial institutions, face the challenge of managing the associated credit risks. It is crucial for these institutions to accurately classify credit card customers as “good” or “bad” to minimize capital loss. This research investigates the approaches for predicting the default status of credit card customer via the application of various machine-learning models, including neural networks, logistic regression, AdaBoost, XGBoost, and LightGBM. Performance metrics such as accuracy, precision, recall, F1 score, ROC, and MCC for all these models are employed to compare the efficiency of the algorithms. The results indicate that XGBoost outperforms other models, achieving an accuracy of 99.4% . The outcomes from this study suggest that effective credit risk analysis would aid in informed lending decisions, and the application of machine-learning and deep-learning algorithms has significantly improved predictive accuracy in this domain.  \nKeywords: credit risk prediction; credit risk; classification; machine learning  \n1. Introduction  \nCredit cards offer an easy method of borrowing money to pay for a range of goods and services in the modern era. Credit cards function as a replacement for cash and debit cards and are also widely used in daily shopping. Moreover, credit cards have become indispensable to the contemporary economy for many individuals. From the view of financial institutions and banks, they must decide whether to approve credit card applications when a customer submits the application. Different factors are considered by creditors when determining whether the customer is good or bad in terms of risk andrepayment. According to practical scenarios, our approach categorizes a “bad customer”as one whose credit has been past due for 60 days or more, whereas a “good customer” isone whose debt has been past due for less than 60 days.  \nCredit scores are a general risk governance strategy in banks and other credit institutions, which utilize the personal data of credit card customers to signify ","cbCaicSZ2CTFrZ8y","https://ap.wps.com/l/cbCaicSZ2CTFrZ8y","pdf",9337809,1,33,"English","en",105,"# Introduction\n## Credit risk and credit scoring\n## Customer segmentation and study goals\n# Methods\n## Machine-learning and deep-learning models\n## Evaluation metrics\n# Results and Discussion\n## Model comparison and best-performing approach\n# Conclusion\n## Implications for lending decisions","[{\"question\":\"How does the study define “good” and “bad” credit card customers?\",\"answer\":\"A “bad customer” is defined as having credit past due for 60 days or more, while a “good customer” has debt past due for less than 60 days.\"},{\"question\":\"Which models are evaluated for credit risk prediction?\",\"answer\":\"The study applies neural networks, logistic regression, AdaBoost, XGBoost, and LightGBM to predict default status.\"},{\"question\":\"What evaluation metrics are used to compare the models?\",\"answer\":\"Models are compared using accuracy, precision, recall, F1 score, ROC, and MCC.\"}]","Credit Risk Prediction Using Machine Learning and Deep Learning -
