Machine learning and analytics for time series data

The O’Reilly Data Show Podcast: Arun Kejariwal and Ira Cohen on building large-scale, real-time solutions for anomaly detection and forecasting.

In this episode of the Data Show, I speak with Arun Kejariwalof Facebook and Ira Cohenof Anodot(full disclosure: I’m an advisor to Anodot). This conversation stemmed from a recent online panel discussion we did, where we discussed time series data, and, specifically, anomaly detection and forecasting. Both Kejariwal (at Machine Zone, Twitter, and Facebook) and Cohen (at HP and Anodot) have extensive experience building analytic and machine learning solutions at large scale, and both have worked extensively with time-series data. The growing interest in AI and machine learning has not been confined to computer vision, speech technologies, or text. In the enterprise, there is strong interest in using similar automation tools for temporal data and time series.

We had a great conversation spanning many topics, including:

  • Why businesses should care about anomaly detection and forecasting; specifically, we delve into examples outside of IT Operations & Monitoring.
  • (Specialized) techniques and tools for automating some of the relevant tasks, including signal processing, statistical methods, and machine learning.
  • What are some of the key features of an anomaly detection or forecasting system.
  • What lies ahead for large-scale systems for time series analysis.
