In Chapter 3, Basic Algorithms – Classification, Regression, and Clustering, you already saw how to get the required .jar file for ELKI. We will follow a similar process, as follows:

Open Command Prompt or Terminal, and execute the following command:

java -jar elki-bundle-0.7.1.jar

This will provide the GUI interface, as shown in the following screenshot:

In the GUI, the dbc.in and algorithm parameters are highlighted and need to be set. We will use pov.csv file, as dbc.in. This CSV file can be downloaded from https://github.com/elki-project/elki/blob/master/data/synthetic/ABC-publication/pov.csv.

For the algorithm, select outlier.clustering.EMOutlier, and in em.k, pass 3 as the value. The following screenshot shows all of the filled-in options:

Click on the Run Task button, and it will process and generate the following output:

This shows clustering and the possible outliers.
