Until recently, Arun 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.
In the wake of IoT becoming ubiquitous, there has been a large interest in the industry to develop novel techniques for anomaly detection at the Edge. Example applications include, but not limited to, smart cities/grids of sensors, industrial process control in manufacturing, smart home, wearables, connected vehicles, agriculture (sensing for soil moisture and nutrients). What makes anomaly detection at the Edge different? The following constraints be it due to the sensors or the applications necessitate the need for the development of new algorithms for AD.
Guaranteeing privacy In this talk we shall throw light on the above in detail. Subsequently, we shall walk through the algorithm design process for anomaly detection at the Edge. Specifically, we shall dive into the need to build small models/ensembles owing to limited memory on the sensors. Further, how to training data in an online fashion as long term historical data is not available due to limited storage. Given the need for data compression to contain the communication overhead, can one carry out anomaly detection on compressed data? We shall throw light on building of small models, sequential and one-shot learning algorithms, compressing the data with the models and limiting the communication to only the data corresponding to the anomalies and model description. We shall illustrate the above with concrete examples from the wild!
