java.lang.Object weka.filters.Filter weka.filters.unsupervised.attribute.AddCluster
A filter that adds a new nominal attribute representing the cluster assigned to each instance by the specified clustering algorithm.
Valid filter-specific options are:
-W clusterer string
Full class name of clusterer to use, followed by scheme options. (required)
-I range string
The range of attributes the clusterer should ignore. Note: if a class index
is set then the class is automatically ignored during clustering.
