ELKI tool - outlier detection results for ABOD

Question

I am trying to run ELKI for Outlier Detection using ABOD method. I see the various visualizations as result, but not the outlier scores or rankings. What should I do to say get top 10 outliers using ELKI?

Answer 1

The ELKI ResultWriter will write the outliers to a file in decreasing outlierness (if the method is implemented with the appropriate metadata to allow correct sorting).

As for ABOD, please not that the implementation you are using (ELKI 0.6.0~beta2 and before) is actually FastABOD, unless you set abod.k to the data set size. The 0.6.0 release will have separate classes for ABOD, FastABOD and LB-ABOD. But since ABOD scales O(n^3) it will be only usable for small data sets!

Answer 2

You can see the result if you use the cmd (command line) for running the algorithm like this

java -cp <<path>> -algorithm outlier.ABOD -dbc.in data.txt -out myresults/ABOD

, on <<path>> that containd elki.jar/elki.jar de.lmu.ifi.dbs.elki.application.KDDCLIApplication
