Real-Time Fraud Detection at Scale—Integrating Real-Time Deep-Link Graph Analytics with Spark AI

Download Slides

As data grows in size and connectedness dramatically in all dimensions, the potential for graph-enriched machine learning grows likewise, but scalable technologies are needed to both build models and apply them in real-time. Real-time deep-link graph pattern matching and analytics provides new opportunities for enriching your machine learning models with graph features.

‘In addition to the real-time deep-link aspect, the ability to process large datasets in a production pipeline provides a synergistic approach for the two distributed and performant platforms: Spark and TigerGraph. The TigerGraph graph database provides scalable real-time deep link graph analytics and augments Spark with graph analytics and predictions for a wide range of Machine Learning use cases.

In this session, we will explain the architecture and technical implementation for a TigerGraph+Spark graph-enhanced Machine Learning pipeline: Use TigerGraph both before training to extract (graph and non-graph) features and after training to apply the model on streaming data; use Spark to train and tune machine learning models at scale. As an example, we will present a solution in production at China Mobile that detects and prevents phone-based scams using machine learning with TigerGraph.

Specifically, the solution generates 118 graph features for 600 million users, to feed a machine learning system which detects three types of unwanted phone calls. TigerGraph then helps to deploy the model by extracting these 118 features in real-time for up to 10,000 calls per second, to give customers a real-time diagnosis of their incoming calls.
