This CSAFE webinar was presented by Dr. Padhraic Smyth from University of California, Irvine on September 28, 2017.

Description:

Time-series of user-generated events are routinely captured and logged on devices such as computers and mobile phones. This type of data is of increasing interest in forensic investigations. There has been relatively little use of statistical thinking in this context, for a variety of reasons. In this talk we will discuss recent work at UC Irvine (under CSAFE) that has begun to develop statistical techniques to answer basic questions about such data, building on methods such as marked point processes. We will outline the methodological approach and describe results to date on both simulated and real-world data. The talk will conclude with a brief discussion of challenges in this area as well as some thoughts on future research directions.
