About this model
Scores every alert raised by the transaction monitoring system on how likely it is to end in a suspicious transaction report, so investigators work the riskiest alerts first and low-risk alerts get a lighter review. Each score carries reason codes (structuring pattern, high-risk jurisdiction counterparty, unusual cash activity for the profile).
Intended use
Queue ordering and review-depth routing for Financial Crime Compliance investigators. No alert is closed by the model: low-scored alerts still get a documented human review, and sampling checks the low band every month.
Training data lineage
Rebuilt from the SAS Enterprise Miner alert-scoring model used by Financial Crime since 2021. Trained on three years of dispositioned alerts in aml-alerts-history, with customer activity features from casa-transactions, in BigQuery and Vertex AI. Tier 1 model validated by Model Risk Management; below-the-line testing and champion-challenger against the SAS model ran for two months before switch-over.
Limitations & bias notes
Learns from past investigator decisions, so any historical under-reporting pattern can carry through; the low band is sampled monthly to catch this. New typologies need new monitoring scenarios first; the model does not raise alerts itself.
