Optimizing Loan Default Prediction with Feature Selection
A leading financial institution faced challenges in accurately predicting loan defaults due to high-dimensional and noisy tabular data. Traditional models struggled with interpretability and efficiency.
Challenge: Identify the most impactful features from a vast array of financial metrics and customer data to improve loan default prediction accuracy and reduce false positives, while maintaining model interpretability for regulatory compliance.
Solution: Implemented a hybrid feature selection approach combining filter-based methods for initial screening (e.g., correlation, mutual information) with wrapper-based methods (e.g., recursive feature elimination with Lasso regularization) to fine-tune the feature set. This iterative process ensured both relevance and non-redundancy.
Outcome: Achieved a 15% reduction in false positive rates and a 10% increase in predictive accuracy. The refined feature set, comprising key financial indicators and behavioral patterns, significantly improved model explainability, facilitating easier compliance audits and faster decision-making.

Real-time Personalization in E-commerce with RL and Generative AI
An e-commerce platform sought to enhance real-time product recommendations and user experience by dynamically adapting to evolving customer preferences. Traditional feature engineering was too slow and static.
Challenge: Develop a system that can continuously learn and generate optimal features from streaming user interaction data, product attributes, and seasonal trends to provide highly personalized recommendations with minimal latency.
Solution: Deployed a reinforcement learning (RL) framework to dynamically select and transform features based on real-time user feedback (clicks, purchases, views). Generative AI models were then used to create a continuous embedding space of feature transformations, allowing for efficient, gradient-based optimization and the generation of novel, context-aware features. This hybrid approach allowed for rapid adaptation to changing user behavior.
Outcome: Resulted in a 20% increase in click-through rates and a 15% boost in conversion rates for personalized recommendations. The system now provides highly relevant product suggestions, leading to improved customer satisfaction and revenue growth, with features updated and optimized autonomously every hour.
