- Abstract:
-
An outlier is a data point that is significantly diff erent from the others in a data set. One person’s noise could be another person ’s signal, and therefore the problem of outlier mining attracts more and more interests in research of information science when the research fields of data quality, fraud detection, i ntrusion detection, fault diagnosis, military scout and so on receive wide atten tions. In this paper, a survey was presented for the problem of outlier mining from the basic concepts to the principal research problems and the underlying te chniques, including origination of outlier, definition of outlier and the compar ison of popular outlier mining methods. A summary of th e current state of the art of these techniques, a discussion on future rese arch topics, and the challenges of the outlier mining were also presented.
