Which algorithms are used in this personal loan classification project?

The system implements and compares two regression algorithms: Lasso Regression (L1 regularization) and Ridge Regression (L2 regularization). Ridge Regression achieved superior performance with 92.4% accuracy and 0.967 ROC-AUC.

What is the accuracy of the personal loan acceptance prediction model?

The Ridge Regression model achieves 92.4% accuracy with an F1-score of 0.8974 and ROC-AUC of 0.9672, demonstrating excellent predictive capability for customer targeting.

Who can benefit from this personal loan classification system?

Banking institutions, marketing teams, loan officers, financial analysts, and researchers can use this system for targeted marketing campaigns, customer segmentation, and improving loan conversion rates.

What technologies are used to build this project?

The project is built using Python with Pandas, NumPy, Scikit-learn, and imbalanced-learn for machine learning. The web interface is developed using Flask with HTML, CSS, and JavaScript.

ChipGuard Intelligent Bank Personal Loan Classification System

The ChipGuard Intelligent Bank Personal Loan Classification System is a comprehensive machine learning solution that predicts personal loan acceptance using customer demographic and financial data. This project is ideal for B.Tech, MCA, CSE, and engineering students as their final year project. It implements Lasso Regression and Ridge Regression with leak-free SMOTE oversampling, achieving 92.4% accuracy and 0.967 ROC-AUC.

The system utilizes the Universal Bank Personal Loan Dataset comprising 5,000 customer records with 14 features including income, age, credit card spending, mortgage, education, family size, and banking behavior attributes. It provides an interactive web-based platform for data upload, model training, and real-time loan acceptance prediction, enabling banking institutions to run targeted marketing campaigns and improve customer acquisition efficiency.
