public class AddCluster extends Filter implements UnsupervisedFilter, OptionHandler
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.

      public boolean setInputFormat(Instances instanceInfo) throws Exception
      Sets the format of the input instances.
      覆盖:
      setInputFormat 在类中 Filter
      参数:
      instanceInfo - an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required).

      返回:
      true if there are instances pending output
      抛出:
      IllegalStateException - if no input structure has been defined
      NullPointerException - if no input structure has been defined,
      Exception - if there was a problem finishing the batch.
    • input

      public boolean input(Instance instance) throws Exception
      Input an instance for filtering. Ordinarily the instance is processed and made available for output immediately. Some filters require all instances be read before producing output.

      参数:
      instance - the input instance
      返回:
      true if the filtered instance may now be collected with output().
      抛出:
      IllegalStateException - if no input format has been defined.
      NullPointerException - if the input format has not been defined.
      Exception - if the input instance was not of the correct format or if there was a problem with the filtering.
