Challenges in using machine learning for financial monitoring By Leah McFarland, State Street

Описание: Leah McFarland, Product Management, State Street is speaker at Global Artificial Intelligence Virtual Conference Mar 17th to 19th 2022.

Topic: Challenges in using machine learning for financial monitoring

Abstract:
Shifting from rules-based to machine learning-based financial monitoring reduces false positive alerts and increases escalation rates (ie, alerts selected for further investigation)
In conjunction with entity resolution/network generation logic, it also enables enhanced visualizations in support of investigations
However, notwithstanding the above, there continue to be multiple challenges in making this important transition, including:
Supervised machine learning uses suspicious activity reports (SARs) as a target, but these may be of low quality (eg, “defensive” filing)
Changes in underlying data over time (ie, data drift) require model retraining, but regulatory requirements on model validation extend this process
To move toward real-time data processing and/or more continuous model retraining requires greater maturity in model lifecycle management
There remains much greater scope for reduction of false positives, given:
Rates are still high even after initial machine learning adoption
Historical approaches to monitoring models have been backward (eg, identify rare data pattern and impose blanket rules)
Regulations and their application are ambiguous in not significantly distinguishing between low- and high-risk activities
There is insufficient attention to how compliance costs serve as a barrier to access to financial services
Increasing adoption of blockchain involves a novel data processing/storage mechanism only beginning to be subjected to financial monitoring
