类 ClusterMembership
java.lang.Object
weka.filters.Filter
weka.filters.unsupervised.attribute.ClusterMembership
A filter that uses a density-based clusterer to generate cluster membership values; filtered instances are composed of these values plus the class attribute (if set in the input data). If a (nominal) class attribute is set, the clusterer is run separately for each class. The class attribute (if set) and any user-specified attributes are ignored during the clustering operation
Valid options are:
-W <clusterer name> Full name of clusterer to use. eg: weka.clusterers.EM Additional options after the '--'. (default: weka.clusterers.EM)
-I <att1,att2-att4,...> The range of attributes the clusterer should ignore. (the class attribute is automatically ignored)Options after the -- are passed on to the clusterer.

getCapabilities
Returns the Capabilities of this filter.- 指定者:
getCapabilities
在接口中CapabilitiesHandler
- 覆盖:
getCapabilities
在类中Filter
- 返回:
- the capabilities of this object

-
getCapabilities
Returns the Capabilities of this filter, makes sure that the class is never set (for the clusterer).- 覆盖:
getCapabilities
在类中Filter
- 参数:
data
- the data to use for customization- 返回:
- the capabilities of this object, based on the data
- 另请参阅:
-
setInputFormat
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 the outputFormat may be collected immediately
- 抛出:
Exception
- if the inputFormat can't be set successfully
-
batchFinished
Signify that this batch of input to the filter is finished.- 覆盖:
batchFinished
在类中Filter
- 返回:
- true if there are instances pending output
- 抛出:
IllegalStateException
- if no input structure has been definedNullPointerException
- if no input structure has been defined,Exception
- if there was a problem finishing the batch.
-
input
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.- 覆盖:
input
在类中Filter
- 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.
-
listOptions
Returns an enumeration describing the available options.- 指定者:
listOptions
在接口中OptionHandler
- 返回:
- an enumeration of all the available options.
-
setOptions

-I <att1,att2-att4,...> The range of attributes the clusterer should ignore. (the class attribute is automatically ignored)
Options after the -- are passed on to the clusterer.- 指定者:
setOptions
在接口中OptionHandler
- 参数:
options
- the list of options as an array of strings- 抛出:
Exception
- if an option is not supported

-
ignoredAttributeIndicesTipText
Returns the tip text for this property- 返回:
- tip text for this property suitable for displaying in the explorer/experimenter gui
-
getIgnoredAttributeIndices
