2 Let’s define the
Use Case Fast evolving fraud sophistication Ambitions for Fraud Project The Bank advanced analytics blueprint Blue-Print approach to real time scoring of transactions Reduce false-positives & Enhance fraud detection rate ONLY ~40% of fraud cases are detected Low Detection Rate 99.5% of cases are not fraud related Many false positives Challenges for Fraud Detection Tens of Millions € lost each month High Fraud Loss ©2018 Teradata – Santiago Cabrera-Naranjo

5.
5 Modeling Challenges • Class imbalance (100,000:1
non-fraud vs. fraud) • Assigning fraud labels from historic data • Fraud is ambiguous • Not all features available in real-time • Most machine learning sees transactions atomically ©2018 Teradata – Santiago Cabrera-Naranjo

System: 60 transactions/sec.) Ensemble of boosted decision trees and logistic regression. From online validation of the model: ● 25-30% false positive reduction, with over 35% increase in detection rate ● Opportunity to expand model with additional features, retrain on recent data and add additional models to the ensemble. ● Models can be expanded to additional channels Rule Engine on validation set ©2018 Teradata – Santiago Cabrera-Naranjo

17 Current models can only
catch ~70% of all fraud cases Deep Learning Opportunity Traditional ML models view transactions atomically Often missed fraud transactions are part of a series Capturing correlation across many features ©2018 Teradata – Santiago Cabrera-Naranjo
18.
18 Three Deep Learning
Architectures to Deliver Value • Designed for spatial correlated features, but by transforming transactions into a 2D image, we can learn temporal correlated features. • Deeper ConvNet allows learning more complex & general features. Goal: Learn kernels from temporal & static features to gain insight into the characteristics of fraud. • Learn temporal information and classify if the sequence of transactions contains fraud. • Shares knowledge across learning time. Goal: Learn transaction patterns within a window. Two solutions can be tested: flag fraud or predict next transaction and define an error. • Anomaly detection: Learn how to generate normal transactions, potentially large volumes of non-fraud data. • AE provide a low level representation of the data. Goal: Build a model that learns how to generate non-fraud data. To detect fraud, define a reconstruction error rate for the fraud cases Auto-Encoders LSTM ConvNet ©2018 Teradata – Santiago Cabrera-Naranjo
