Explainable Machine Learning for Indian Loan Approval Prediction using Data Balancing and Ensemble Models

Access to credit continues to play a vital role in economic participation, particularly in developing regions where financial inclusion efforts are ongoing. However, loan-approval practices still rely largely on manual assessments or rigid credit scoring rules, which often limit transparency and overlook newer forms of risk information. To address these limitations, this work outlines a machine learning-based framework for loan approval prediction that emphasizes interpretability and regulatory alignment rather than serving as a complete deployed system. The proposed approach integrates data preprocessing, class balancing, and ensemble learning techniques—specifically Random Forest and XGBoost—to identify approval patterns within a merged dataset representing both urban banking and rural lending environments in India. To mitigate the opaque nature typically associated with ensemble models, SHAP-based interpretation is introduced to highlight the influence of individual features on predicted outcomes, enabling clearer communication of decisions to lenders, auditors, and applicants. Although the framework has not yet undergone comprehensive implementation or benchmarking against existing loan-approval platforms, the design contributions are notable. These include the construction of a unified Indian loan dataset, the use of class imbalance handling to address skewed distributions, a structured plan for comparative evaluation of ensemble models, and a transparent explanation component consistent with regulatory expectations. This work is intended as a foundation for future development and testing, with the expectation that full implementation, empirical validation, and comparative studies will form the next phase. If successfully realized, such a platform may support faster, fairer, and more interpretable lending decisions across diverse financial institutions.
