About
Examples of unusual or surprising facts leading to major developments in economics are not hard to find.....In view of the potential importance of unusual and surprising data, it is troubling to see how often outlying observations are discarded without thought or averaged with usual observations by means of "robust" techniques.-- Arnold Zellner, Philosophy and objectives of econometrics in Journal of Econometrics 136 (2007)331-339.
The objective of our research is to use and design data mining techniques, in particular outlier detection, to systematically discover unusual patterns in large and high-dimensional data. Can one be systematic about discovering the unusual? That is the data mining challenge! !
