Machine Learning for Fraud Detection in Streaming Services

The Netflix TechBlog

NOVEMBER 11, 2022

We present a systematic overview of the unexpected streaming behaviors together with a set of model-based and data-driven anomaly detection strategies to identify them. There are two main anomaly detection approaches, namely, (i) rule-based, and (ii) model-based.
