Graph Based Representation Learning for Payment Fraud Prevention

PayPal is at the forefront of applying large scale graph processing and machine learning algorithms to keep fraudsters at bay. In this talk, I¹ll  present how advanced graph processing and machine learning algorithms are applied at PayPal for fraud prevention. I'll give an in-depth overview of emerging area of graph based machine learning. I¹ll elaborate on specific challenges in applying large scale graph processing & machine technique to payment fraud prevention.

I'll present results from experiments conducted on a very large graph data set containing millions of edges and vertices.
