I’m currently in Phoenix, AZ at the 2011 SIAM International Conference on Data Mining.

My contribution is titled “Interpreting and Unifying Outlier Scores”, a method that allows the combination, interpretation, visualization etc. of existing outlier algorithms. The method brings back a bit more statistics into a data mining area that has drifted away from the statistical roots.

We apply the method to a couple of outlier detection algorithms and combine them using a naive ensemble approach, that still outperforms existing outlier ensembles.
