NormalizationFilter
public NormalizationFilter()
inputFormat
public boolean inputFormat(Instances instanceInfo) throws Exception
- 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).
- Returns:
- true if the outputFormat may be collected immediately
- Throws: Exception
- if the input format can't be set
successfully
- Overrides:
- inputFormat in class Filter
input
public boolean input(Instance instance) throws Exception
- Input an instance for filtering. Filter requires all
training instances be read before producing output.
- Parameters:
- instance - the input instance
- Returns:
- true if the filtered instance may now be
collected with output().
- Throws: Exception
- if the input instance was not of the
correct format or if there was a problem with the filtering.
- Overrides:
- input in class Filter
batchFinished
public boolean batchFinished() throws Exception
- Signify that this batch of input to the filter is finished.
If the filter requires all instances prior to filtering,
output() may now be called to retrieve the filtered instances.
- Returns:
- true if there are instances pending output
- Throws: Exception
- if no input structure has been defined
- Overrides:
- batchFinished in class Filter
