weka.filters.unsupervised.attribute.AddCluster
public class AddCluster
A filter that adds a new nominal attribute representing the cluster assigned to each instance by the specified clustering algorithm.
Valid options are:-W <clusterer specification> Full class name of clusterer to use, followed by scheme options. eg: "weka.clusterers.SimpleKMeans -N 3" (default: weka.clusterers.SimpleKMeans)
-I <att1,att2-att4,...> The range of attributes the clusterer should ignore.
