The methods that try to discover re-usable and interpretable patterns in temporal event data have several shortcomings. We contrast several recent approaches to the problem, and extend the T-Pattern algorithm, which was previously applied for detection of sequential patterns in behavioural sciences. The temporal complexity of the T-pattern approach is prohibitive in the scenarios we consider. We remedy this with a statistical model to obtain a fast and robust algorithm to find patterns in temporal data. We test our algorithm on a recent database collected with passive infrared sensors with millions of events.", optnote="ALTRES;ISE", optnote="exported from refbase (http://refbase.cvc.uab.es/show.php?record=1845), last updated on Tue, 12 Jul 2016 10:57:06 +0200", doi="10.3390/s100807496" }
