Method Detail

getQuickInfo

public String getQuickInfo()

Returns a quick info about the object, which can be displayed in the GUI.
Default implementation returns null.

Specified by:

getQuickInfo in interface adams.core.QuickInfoSupporter

Returns:

null if no info available, otherwise short string

check

protected String check(WekaEvaluationContainer cont)

Checks the container whether it can be processed.
Default implementation only ensures that it is not null and predictions are present.

Parameters:

cont - the container to check

Returns:

null if successful, otherwise error message

newContainer

protected WekaEvaluationContainer newContainer(String suffix,
                                               WekaEvaluationContainer cont,
                                               gnu.trove.list.TIntList indices)

Creates a new evaluation container from the specified subset of predictions.

Parameters:

suffix - the suffix for the relation name

cont - the container to use as basis

indices - the indices of the predictions to include in the container

Returns:

the new container

doPostProcess

protected List<WekaEvaluationContainer> doPostProcess(WekaEvaluationContainer cont)

Post-processes the evaluation container.

Parameters:

cont - the container to post-process

Returns:

the generated evaluation containers

postProcess

public List<WekaEvaluationContainer> postProcess(WekaEvaluationContainer cont)

Post-processes the evaluation container.

Parameters:

cont - the container to post-process

Returns:

the generated evaluation containers

check

protected String check(weka.classifiers.Evaluation eval)

Checks the evaluation whether it can be processed.
Default implementation only ensures that it is not null and predictions are present.

Parameters:

eval - the evaluation to check

Returns:

null if successful, otherwise error message

newEvaluation

protected weka.classifiers.Evaluation newEvaluation(String suffix,
                                                    weka.classifiers.Evaluation eval,
                                                    gnu.trove.list.TIntList indices)

Creates a new evaluation from the specified subset of predictions.

Parameters:

suffix - the suffix for the relation name

eval - the Evaluation to use as basis

indices - the indices of the predictions to include in the container

Returns:

the new container

doPostProcess

protected abstract List<weka.classifiers.Evaluation> doPostProcess(weka.classifiers.Evaluation eval)

Post-processes the evaluation.

Parameters:

eval - the evaluation to post-process

Returns:

the generated evaluations

postProcess

public List<weka.classifiers.Evaluation> postProcess(weka.classifiers.Evaluation eval)

Post-processes the evaluation.

Parameters:

eval - the evaluation to post-process

Returns:

the generated evaluations
