Anomaly Detection presented by Ted Dunning

  • March 17, 2014 · 6:30 PM

The basic ideas of anomaly detection are simple. You build a model and you look for data points that don’t match that model. Building a practical anomaly detection system requires deal with practical details starting with algorithm selection, data flow architecture, anomaly alerting, user interfaces and visualizations. We will describe the major classes of anomaly detection systems and show how to build anomaly detection systems for:

a) rate shifts to determine when events such as web traffic, purchases or process progress beacons shift rate

b) topic spotting to determine when new topics appear in a content stream such as Twitter

c) network flow anomalies to determine when systems with defined inputs and outputs act strangely.

While describing how to solve these problems, we will describe how clustering, dimensionality reduction, and density estimation can be used in systems that adapt and learn about their environment and how these systems can tell you when something has changed.

This talk will reprise the content of my Strata presentation, but will include extra material that shows how compression equals truth and how anomaly detection can make databases faster among other sundry philosophical truths.

      Will attempt to stream (subject to 25 max connections). Otherwise should be able to record and post the link: Anomaly detection presented by Ted Dunning

    This meetup coincides with the Bay Area useR (R Lang) March Meetup. I chose this one over the other one and have a good feeling I'll be proven right :-)

      Hacker Dojo has a machine learning group that meets - seems like every other Friday or so; the Data Science Journal meetup is there every two weeks; the ACM has a regular Big Data / ML meeting, the IEEE sometimes has stuff. Then there are a host of application-specific meetups (Hadoop at Yahoo, etc.), and of course there'll be stuff going on at Stanford as well.
