Using AI to Combat Financial Fraud

Credit and bank cards are a major target for fraud. To thwart fraudulent activity, American Express, which boasts over 115 million active credit cards and handles more than eight billion transactions a year, leverages deep learning through the NVIDIA GPU computing platform.

NVIDIA Solutions

American Express uses advanced, long short-term memory (LSTM) models to detect anomalous patterns in transactions. Models are trained on NVIDIA DGX™ for faster time-to-market, optimized with NVIDIA TensorRT™, and served with NVIDIA Triton™ Inference Server for high performance in production.

American Express Results

American Express implemented this enhanced, real-time fraud detection system to improve accuracy, and better protect customers and merchants. The system operates within a tight two-millisecond latency requirement and delivers a 50X improvement over a CPU-based configuration, which failed to meet their goal.

A GPU-accelerated LSTM deep neural network, combined with their long-standing gradient boosting machine (GBM) model—used for regression and classification—has improved fraud detection accuracy by up to six percent in specific segments.

Results

50X the throughput on GPUs vs. CPUs
