Method Detail

init
protected void init()
-
resetLearningImpl
public void resetLearningImpl()
Description copied from class:AbstractClassifier
Resets this classifier. It must be similar to starting a new classifier from scratch.
The reason for ...Impl methods: ease programmer burden by not requiring them to remember calls to super in overridden methods. Note that this will produce compiler errors if not overridden.- Specified by:
resetLearningImpl
in classAbstractClassifier
-
trainOnInstanceImpl
public void trainOnInstanceImpl(MultiLabelInstance instance)
- Specified by:
trainOnInstanceImpl
in interfaceMultiLabelLearner
- Specified by:
trainOnInstanceImpl
in classAbstractMultiLabelLearner
-
transformInstance
protected Instance transformInstance(MultiLabelInstance inst, int outputIndex)
-
isRandomizable
public boolean isRandomizable()
Description copied from interface:Learner
Gets whether this learner needs a random seed. Examples of methods that needs a random seed are bagging and boosting.- Specified by:
isRandomizable
in interfaceLearner<Example<Instance>>
- Returns:
- true if the learner needs a random seed.
-
getModelMeasurementsImpl
protected Measurement[] getModelMeasurementsImpl()
Description copied from class:AbstractClassifier
Gets the current measurements of this classifier.
The reason for ...Impl methods: ease programmer burden by not requiring them to remember calls to super in overridden methods. Note that this will produce compiler errors if not overridden.- Specified by:
getModelMeasurementsImpl
in classAbstractClassifier
- Returns:
- an array of measurements to be used in evaluation tasks
-
getModelDescription
public void getModelDescription(StringBuilder out, int indent)
Description copied from class:AbstractClassifier
Returns a string representation of the model.- Specified by:
getModelDescription
in classAbstractClassifier
- Parameters:
out
- the stringbuilder to add the descriptionindent
- the number of characters to indent
-
getPredictionForInstance
public Prediction getPredictionForInstance(MultiLabelInstance instance)
- Specified by:
getPredictionForInstance
in interfaceMultiLabelLearner
