LoOP: Local Outlier Probabilities

Has been accepted at CIKM 2009 (The 18th ACM Conference on Information and Knowledge Management), November 2-6th 2009, Hong Kong. And will appear in the conference proceedings published by the ACM Press.

It’s an outlier detection method based on LOF (Local Outlier Factor) but a bit more statistically robust and with an easier to interpret score. Given the statistical backing, it works reasonably well on samples such as data pages of an appropriate index structure, reducing complexity to linear for the approximative version.

This publication is a bit special to me: I suggested the approach to my colleagues and they gave me the abstract and title for my birthday. :-)
