AltFinGuard - Inclusive Credit Risk Model Notes

Problem Statement:

  • Traditional credit scoring systems in emerging economies rely heavily on historical financial records.
  • This reliance excludes individuals/small businesses lacking formal financial histories from credit access.
  • Fintech companies are addressing this by using alternative data sources for more inclusive credit assessment models.
  • The project, AltFinGuard, aims to develop such a model for precise risk scoring and smart defaulter tracking to promote greater financial inclusion.

Project Description:

  • Leveraging Alternative Data: Non-traditional data sources are used to evaluate creditworthiness.
  • Accurate Default Prediction: Probability of Default (PD) is predicted with improved accuracy using modern ML models.
  • Real-Time Defaulter Tracking: Potential defaulters are identified and monitored in real time for proactive risk management.
  • Financial Inclusion & Compliance: Improves access to credit while strictly following data privacy standards like GDPR and the DPDP Bill in India.
  • AltFinGuard is built to be clear, scalable, and compliant, supporting responsible innovation in credit risk management.

Datasets Used:

  • Telecom Data: Call duration, frequency, recharge patterns, and SMS logs provide information about financial stability and behavior.
  • Utility Bills: Timely or delayed payments on electricity, water, and gas bills show payment consistency.
  • Mobile Wallet & E-commerce Transactions: Analysis of spending categories, frequency, and average order value gives a picture of finances.
  • Social Media Metadata: Activity level, connections, and engagement rate are indicators of stability and reliability.
  • Device Metadata: Geolocation tracking, SIM swap detection, and login history help confirm identity and evaluate fraud risk.
  • Demographics & Public Records: Region, occupation, estimated income, and court case lookups add to the behavioral data.

Solution Approach:

  • Data Preprocessing & Feature Engineering: Cleaning, transforming, and extracting useful features from raw alternative data is essential for model use, data quality, and relevance.
  • Model Training (XGBoost/LightGBM): Strong gradient boosting frameworks manage complex datasets effectively and accurately. These models learn to identify credit risk patterns.
  • PD Estimation & Risk Classification: Calculating the Probability of Default (PD) for each applicant categorizes them into specific risk tiers, providing a measurable credit risk assessment.
  • Real-Time Defaulter Tracking: Tools using geo-IP and SIM data monitor and identify possible defaulters in real time, allowing for early interventions and lowered potential losses.
  • Frontend + Backend Deployment: A strong, scalable structure is built for easy deployment and user interaction, including a simple interface and a strong backend to support the model's operations.

Innovation and Compliance:

  • Explainable AI with SHAP Values: SHAP (SHapley Additive exPlanations) values give clear, understandable reasons for each credit decision, building trust and accountability.
  • Live Defaulter Tracking Dashboard: An interactive dashboard offers real-time insights into defaulter patterns and alerts, helping lenders monitor and reduce risks actively.
  • GDPR/DPDP Compliance: AltFinGuard is designed with privacy in mind, fully complying with data protection laws like GDPR and India's DPDP Bill, ensuring data is used securely and ethically.
  • Modular & Scalable Cloud-Native Architecture: The cloud-native architecture is built for flexibility and growth, enabling easy integration, quick deployment, and smooth scaling to meet changing demands.

Intuitive Dashboard for Risk Management:

  • The dashboard offers a clear and interactive interface for lenders to manage credit risk effectively, focusing on clarity and user experience.
  • 3D-Themed Cards: PD Score & Defaulter Tracker: Visually appealing cards quickly show Probability of Default (PD) and defaulter status.
  • Interactive Dashboard with Search & Alerts: Easily search through data and get real-time alerts about suspicious activities or changes in risk profiles.
  • Visual Widgets Showing User Risk Profile: Detailed visual widgets break down individual risk profiles, providing specific insights into different risk factors and their contributions to the overall score.
