QUESTION
I am trying to run K-Means using ELKI MiniGUI. I have a CSV dataset of 15 features (columns) and a label column. I would like to do multiple runs of K-Means with different combinations of the feature columns.
Is there anywhere in the MiniGUI where I can specify the indeces of which columns I would like to be used for clustering?
