Using Weka on the command line to generate a clustered arff file

Question

In weka explorer, you can perform data clustering and then use visualization to save a new arff file with the cluster as attributes.

Is there a way to do this automatically by calling executables on the command line?

Answer 1

If anyone else has this problem, you can try using weka.filters.unsupervised.attribute.AddCluster. The -W argument should contain your clustering algorithm, and you can use -i and -o, like any other filter, to save the new arff.
