Constructor Detail

TKSVMlightStringOutcomeDataWriter

public TKSVMlightStringOutcomeDataWriter(File outputDirectory)
                                  throws IOException

Constructor for the One verse All Tree Kernel SVMlight data writer.

Throws:

IOException

Method Detail

writeEncoded

public void writeEncoded(TreeFeatureVector features,
                         Integer outcome)
                  throws org.cleartk.classifier.CleartkProcessingException

Write the feature vector into the appropriate files (ultimately, it's one line in each of the model file.)

Specified by:

writeEncoded in class org.cleartk.classifier.jar.DataWriter_ImplBase<TKSVMlightStringOutcomeClassifierBuilder,TreeFeatureVector,String,Integer>

Parameters:

features - The feature vector to be written.

outcome - The index of the model file which this feature vector corresponds to. If null this feature vector has no known "outcome".

Throws:

org.cleartk.classifier.CleartkProcessingException

finish

public void finish()
            throws org.cleartk.classifier.CleartkProcessingException

Callback called after the last feature vector has been written. Flushes the various streams and deletes the all false file.

Specified by:

finish in interface org.cleartk.classifier.DataWriter<String>

Overrides:

finish in class org.cleartk.classifier.jar.EncodingDirectoryDataWriter<TKSVMlightStringOutcomeClassifierBuilder,org.cleartk.classifier.Classifier<String>,TreeFeatureVector,String,Integer>

Throws:

org.cleartk.classifier.CleartkProcessingException

newClassifierBuilder

protected TKSVMlightStringOutcomeClassifierBuilder newClassifierBuilder()

Specified by:

newClassifierBuilder in class org.cleartk.classifier.jar.DirectoryDataWriter<TKSVMlightStringOutcomeClassifierBuilder,org.cleartk.classifier.Classifier<String>>
