java.lang.Objectweka.filters.Filter
weka.filters.unsupervised.attribute.ClusterMembership
A filter that uses a clusterer to obtain cluster membership probabilites for each input instance and outputs them as new instances.
Valid filter-specific options are:
Full class name of clusterer to use. Clusterer options may be specified at the end following a -- .(required)
-I range string
The range of attributes the clusterer should ignore. Note:
the class attribute (if set) is automatically ignored during clustering.

public boolean setInputFormat(Instances instanceInfo)
throws java.lang.Exception
setInputFormat in class FilterinstanceInfo - an Instances object containing the input instance
structure (any instances contained in the object are ignored - only the
structure is required).
java.lang.Exception - if the inputFormat can't be set successfully
public boolean batchFinished()
throws java.lang.Exception
batchFinished in class Filterjava.lang.IllegalStateException - if no input structure has been defined
java.lang.Exception - if there was a problem finishing the batch.
public boolean input(Instance instance)
throws java.lang.Exception
input in class Filterinstance - the input instance
java.lang.IllegalStateException - if no input format has been defined.
java.lang.Exception - if the input instance was not of the correct
format or if there was a problem with the filtering.public java.util.Enumeration listOptions()
listOptions in interface OptionHandler
public void setOptions(java.lang.String[] options)
throws java.lang.Exception
-W clusterer string
Full class name of clusterer to use. Clusterer options may be
specified at the end following a -- .(required)
-I range string
The range of attributes the clusterer should ignore. Note:
the class attribute (if set) is automatically ignored during clustering.
setOptions in interface OptionHandleroptions - the list of options as an array of strings
java.lang.Exception - if an option is not supportedpublic java.lang.String[] getOptions()

newClusterer - the clusterer to usepublic DensityBasedClusterer getDensityBasedClusterer()
public java.lang.String ignoredAttributeIndicesTipText()
public java.lang.String getIgnoredAttributeIndices()
public void setIgnoredAttributeIndices(java.lang.String rangeList)
rangeList - a string representing the list of attributes.
eg: first-3,5,6-last
java.lang.IllegalArgumentException - if an invalid range list is suppliedpublic static void main(java.lang.String[] argv)
argv - should contain arguments to the filter: use -h for help
