weka.filters.unsupervised.attribute.MakeIndicator
| MakeIndicator | | public class MakeIndicator extends Filter implements UnsupervisedFilter,StreamableFilter,OptionHandler(Code) | |
A filter that creates a new dataset with a boolean attribute replacing a nominal attribute. In the new dataset, a value of 1 is assigned to an instance that exhibits a particular range of attribute values, a 0 to an instance that doesn't. The boolean attribute is coded as numeric by default.
Valid options are:
-C <col>
Sets the attribute index.
-V <index1,index2-index4,...>
Specify the list of values to indicate. First and last are
valid indexes (default last)
-N <index>
Set if new boolean attribute nominal.

true if new attribute is to be numeric |
| getOptions | | public String[] getOptions()(Code) | | Gets the current settings of the filter.
an array of strings suitable for passing to setOptions |
| getValueIndices | | public String getValueIndices()(Code) | | Get the indices of the indicator values.
the indices of the indicator values |
| getValueRange | | public Range getValueRange()(Code) | | Get the range containing the indicator values.
the range containing the indicator values |
| globalInfo | | public String globalInfo()(Code) | | a description of the filter suitable fordisplaying in the explorer/experimenter gui |
| input | | public boolean input(Instance instance)(Code) | | Input an instance for filtering. The instance is processed
and made available for output immediately.
Parameters:
instance - the input instance true if the filtered instance may now becollected with output().
throws:
IllegalStateException - if no input format has been set. |
| listOptions | | public Enumeration listOptions()(Code) | | Returns an enumeration describing the available options.
an enumeration of all the available options. |
| main | | public static void main(String[] argv)(Code) | | Main method for testing this class.
Parameters:
argv - should contain arguments to the filter: use -h for help |
| numericTipText | | public String numericTipText()(Code) | | tip text for this property suitable fordisplaying in the explorer/experimenter gui |
| setAttributeIndex | | public void setAttributeIndex(String attIndex)(Code) | | Sets index of the attribute used.
Parameters:
attIndex - the index of the attribute |
| setInputFormat | | public boolean setInputFormat(Instances instanceInfo) throws Exception(Code) | | Sets the format of the input instances.
Parameters:
instanceInfo - an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required). true if the outputFormat may be collected immediately
throws:
UnsupportedAttributeTypeException - the selecte attribute is not nominal
throws:
UnsupportedAttributeTypeException - the selecte attribute has fewer than two values. |
| setNumeric | | public void setNumeric(boolean bool)(Code) | | Sets if the new Attribute is to be numeric.
Parameters:
bool - true if new Attribute is to be numeric |
| setOptions | | public void setOptions(String[] options) throws Exception(Code) | | Parses a given list of options.
Valid options are:
-C <col>
Sets the attribute index.
-V <index1,index2-index4,...>
Specify the list of values to indicate. First and last are
valid indexes (default last)
-N <index>
Set if new boolean attribute nominal.
Parameters:
options - the list of options as an array of strings
throws:
Exception - if an option is not supported |
| setValueIndex | | public void setValueIndex(int index)(Code) | | Sets index of the indicator value.
Parameters:
index - the index of the indicator value |
| setValueIndices | | public void setValueIndices(String range)(Code) | | Sets indices of the indicator values.
Parameters:
range - the string representation of the indicator value indices
See Also: Range |
| setValueIndicesArray | | public void setValueIndicesArray(int[] indices)(Code) | | Set which attributes are to be deleted (or kept if invert is true)
Parameters:
indices - an array containing indexes of attributes to select.Since the array will typically come from a program, attributes are indexedfrom 0.
throws:
InvalidArgumentException - if an invalid set of ranges is supplied |
