Anti Money Laundering (AML)
1) Threshold Calibration: Recalibrated thresholds using Above-The-Line (ATL) and Below-The-Line (BTL) methodologies to enhance detection accuracy.
2) False Positive Suppression Model: Developed machine learning models utilizing Random Forest and XGBoost techniques to minimize false positives while maintaining minimal event loss. Achieved a 44% reduction in alerts with a 1.2% event loss. Employed GridSearchCV for hyperparameter tuning and trained the models with a focus on recall metrics. Trained and deployed 43 models in the Data Warehouse (DWH) for operational use.
3) Overlap Analysis: Identified AML rules with intersections greater than 95% either individually or in combination, enabling control over alert generation and preventing account repetition.
4) Scenario Validation: Validated the current thresholds for all existing rules to ensure the accuracy of the deployed AML application. Conducted analyses and provided observations to the client for necessary adjustments.
