Arun Kejariwal is an independent lead engineer. Previously, he was he was a statistical learning principal at Machine Zone (MZ), where he led a team of top-tier researchers and worked on research and development of novel techniques for install-and-click fraud detection and assessing the efficacy of TV campaigns and optimization of marketing campaigns, and his team built novel methods for bot detection, intrusion detection, and real-time anomaly detection; and he developed and open-sourced techniques for anomaly detection and breakout detection at Twitter. His research includes the development of practical and statistically rigorous techniques and methodologies to deliver high performance, availability, and scalability in large-scale distributed clusters. Some of the techniques he helped develop have been presented at international conferences and published in peer-reviewed journals.

Anomaly detection plays a key role in the context of analysis of real-time streams. This is exemplified by, say, detection incidents in real life from tweet storms. Arun Kejariwal and Karthik Ramasamy walk you through how anomaly detection is supported in real-time data streams in Heron—the streaming system built in-house at Twitter (and open sourced) for real-time computation.
