Making Anomaly Detection at Netflix Actionable with Tableau

Anomaly detection is a process of identifying data points that don’t correspond to normal behavior. There are many anomaly detection algorithms and tools that work on big data. At Netflix, we use a variant of Singular Value Decomposition to detect anomalies on hundreds of thousands of micro time series data. However, detection is only 50% of the solution. With volume, velocity and variety of data increasing, the number of anomalies detected also increases. Making anomalies actionable and enabling triaging are challenges that many organizations face.

In this session, we will present a case study on anomaly detection in time series data. We will specifically talk about an application, surrounding payment processing at Netflix. With more than 62 million customers in over 50 countries, Netflix has to ensure that the payment methods provided by customers do not fail due to processing problems in the payment network. A typical payment transaction goes through at least 4 external participants (issuers, acquirers, payment gateways, processors, etc...) in addition to Netflix’s systems. The wide array of banks that customers use to pay for Netflix creates hundreds of thousands of micro time series data and the complexity of the transaction necessitates a need for a robust anomaly detection system.

We will provide an overview of the algorithm that detects anomalies and also discuss how Tableau fits into the overall solution. We will talk about some core functionalities in Tableau that enable us to personalize anomalies and provide business users enough context to take action without the need for manual triaging.

Vannor Phan leads Payments Fraud Analytics at Netflix. He is responsible for providing insights and analytical tools to mitigate payments fraud. This is accomplished through a combination of data engineering and data visualizations. With a background in mathematics, Vannor is passionate about solving problems and creating data products that use math as its centerpiece.

Albert Wong has been in the business intelligence, data warehousing, and analytics industry for ten-plus years helping people get the most out of their data. He is currently developing Netflix's ecosystem of tools for reporting and visual analysis. Tableau has been a wonderful addition to Netflix's toolset for the last three years, and Albert loves sharing their experience as well as some of the solutions we've engineered to enrich its capabilities.

Jeffrey Wong is a versatile data scientist and engineer. He enjoys research as well as software development; his favorite areas of work are in computational science, statistical computing, modeling, and mathematical optimization. His goal is to develop entire frameworks to improve data science.

1) Research and derive new mathematical models that will quantify business intuition
2) Develop scalable and fast algorithms for said models
3) Architect and collaborate with engineers to build large scale data science systems
4) Make data science accessible through interactive visualization and self serve portals.
As a side interest he likes to study cooperative AI, specifically multiplayer pursuit evasion games and their application to crime as well as search and rescue
