Built-in Code for LOF Outlier Detection

Shubha

Hi,

How can I see the built-in code for the operator, "LOFOutlierDetection"?

Also, is there a paper on which the code is built?

Thanks,
Shubha

Well, I'd suggest to have a look into the source code that is shipped with RapidMiner ... .... seriously, have a look into the [tt]operators.xml[/tt], look for the entry of the operator, note the class in which the operator is implemented and then simply inspect that class ...

I don't know exactly, but I think it is build on:

• Markus M. Breunig , Hans-Peter Kriegel , Raymond T. Ng , Jörg Sander, LOF: identifying density-based local outliers, Proceedings of the 2000 ACM SIGMOD international conference on Management of data, p.93-104, May 15-18, 2000, Dallas, Texas, United States
  

Kind regards,
Tobias
