To construct and validate an optimized XGBoost-based prediction system for small and medium-sized enterprise (SME) loan default risk in commercial banking.
Extracted financial, non-financial, and macroeconomic indicators from commercial bank SME loan data, applying data cleaning and feature engineering.
Trained and optimized an XGBoost model via grid search and cross-validation, comparing performance against logistic regression, random forest, and LightGBM.
Assessed predictive accuracy, stability, and generalization using confusion matrices, ROC curves, and AUC on training and independent test sets.
The optimized XGBoost model achieved an AUC of 0.89 during model evaluation.
The model maintained an AUC of 0.88 on an independent test set, demonstrating robust predictive accuracy, stability, and resistance to overfitting compared to alternative models.
