AddCluster

java.lang.Object
- weka.filters.Filter
- - weka.filters.unsupervised.attribute.AddCluster

All Implemented Interfaces:

java.io.Serializable, CapabilitiesHandler, CapabilitiesIgnorer, CommandlineRunnable, OptionHandler, RevisionHandler, WeightedAttributesHandler, WeightedInstancesHandler, UnsupervisedFilter
```
public class AddCluster
extends Filter
implements UnsupervisedFilter, OptionHandler, WeightedAttributesHandler, WeightedInstancesHandler
```
A filter that adds a new nominal attribute representing the cluster assigned to each instance by the specified clustering algorithm.
Either the clustering algorithm gets built with the first batch of data or one specifies are serialized clusterer model file to use instead.
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)
 
```
```
 -serialized <file>
  Instead of building a clusterer on the data, one can also provide
  a serialized model and use that for adding the clusters.
 
```
```
 -I <att1,att2-att4,...>
  The range of attributes the clusterer should ignore.
 
```
