Cloud-Native AI for Fraud Prevention with Bayesian Networks
summary
Claims a deployed system combining reinforcement learning with Bayesian networks and real‑time architecture that processes up to 42,000 transactions per second with sub‑200 ms latency and scales to 47,000 tps in some layers. It ingests ~3,700 data signals and engineers 847 features, resampling 3.8 million transactions hourly to address class imbalance. Reported results: 33% reduction in false positives (2.4% to 1.42%), a ~33% lift to ~99% detection rate, 12 parallel A/B cohorts at 2.7M txns/day each, and continuous drift detection.
