The primary research question investigates how integrating an interpretable machine learning approach can improve the accuracy and transparency of loan approval processes. We employed LightGBM, a gradient-boosting framework for loan approval classification, optimized via Random Search hyperparameter tuning and validated using 10-fold cross-validation. We incorporated the Shapley Additive exPlanations (SHAP) framework to address the challenge of interpretability in machine learning. The LightGBM model outperformed conventional algorithms (Decision Tree, Random Forest, AdaBoost, and Extra Trees) in accuracy (98.13%), precision (97. 78%), recall (97.17%), and F1-score (97.48%). The study demonstrates that using an interpretable machine learning approach with LightGBM and SHAP can significantly improve the accuracy and transparency of loan approval decisions. This method offers a promising avenue for financial institutions to enhance their loan approval mechanisms, ensuring more reliable, efficient, and transparent decision-making in the digital economy. The study also underscores the importance of interpretability in deploying machine learning solutions in sectors with significant socioeconomic impacts.  \nKeywords: Artificial Intelligence, Light Gradient Boosting Machine, Machine Learning, SHAP  \nReceived for review: 13-03-2024; Accepted: 27-03-2024; Published: 01-04-2024  \nDOI: 10.24191/mjoc.v9i1.25691  \n1. Introduction  \nLoans are pivotal in facilitating financial transactions and enabling individuals and businesses to realize their aspirations (Kariv & Coleman, 2015) . Whether for purchasing a home, expanding a business, or covering unexpected expenses, loans are integral to economic growth and personal advancement (Makinde, 2016; Saiti & Trenovski, 2022).

As the demand for loans continues to rise, the need for effective and efficient loan approval mechanisms becomes increasingly crucial (Dansana et al., 2023) .  \nTraditionally, the loan approval process has been characterized by manual assessment methods that rely heavily on historical data and rigid criteria (Tchakoute Tchuigoua, 2018) . These traditional approaches often struggle to adapt to the evolving landscape of financial dynamics, resulting in inefficiencies and suboptimal decision-making. The limitations of these methods become particularly evident when faced with complex and dynamic economic conditions, leading to delays, inaccuracies, and, sometimes, overlooking potentially creditworthy applicants (","cbCaiankkK6uskuF","https://ap.wps.com/l/cbCaiankkK6uskuF","pdf",674075,1,12,"English","en",105,"# Abstract\n# Keywords\n# Introduction\n## Background of loan approval\n## Traditional assessment limitations\n## Machine learning and LightGBM\n## Need for transparency and interpretability","[{\"question\":\"What is the main goal of the study on loan approval?\",\"answer\":\"To improve loan approval decision-making in the digital economy by using an interpretable machine learning approach that increases accuracy and transparency.\"},{\"question\":\"Which model and explanation method are used in the research?\",\"answer\":\"The study uses LightGBM for classification and applies SHAP (Shapley Additive exPlanations) to provide interpretability for decision rationales.\"},{\"question\":\"How is the LightGBM model validated and tuned?\",\"answer\":\"The LightGBM model is optimized using Random Search hyperparameter tuning and validated with 10-fold cross-validation.\"}]","ENHANCING LOAN APPROVAL DECISION-MAKING -
