- Enhance modeling infrastructure, labeling processes, feature engineering, and algorithms to improve robustness, automation, and generalization, while reducing both modeling and operational burden on risk management teams and easing the integration of new products and risk areas.
- Drive improvements in risk-related machine learning practices, focusing on privacy and compliance, interpretability, and advanced risk perception and analysis.
