The IEEE ICDM 2008 Data Mining Contest is, simply put, about keeping the world safe using data mining. This contest is about developing and testing data mining techniques to verify worldwide compliance of the global ban on nuclear tests. Such tests can be detected by measuring the amount of special xenon isotopes. Obviously, it's not just that simple; these isotopes are also emitted during various legal activities. This talk will describe the domain of the data set used and will give an analysis of the results of the contest.
