Method Detail

setPreSampleSize

public void setPreSampleSize(int preSampleSize)

Set the size of the sample the pilot estimator will be trained with. Default is half the dataset.

Parameters:

preSampleSize -

getPilot

public org.api4.java.ai.ml.classification.IClassifier getPilot()

setPilot

public void setPilot(org.api4.java.ai.ml.classification.IClassifier pilot)

setPreviousRun

public void setPreviousRun(OSMAC<org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>> previousRun)

Description copied from interface: IRerunnableSamplingAlgorithmFactory

Set the previous run of the sampling algorithm, if one occurred, can be set here to get data from it.

Specified by:

setPreviousRun in interface IRerunnableSamplingAlgorithmFactory<org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>,OSMAC<org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>>>

Parameters:

previousRun - Algorithm object of the previous of the sampling algorithm.

getAlgorithm

                                                                                          org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?> inputDataset,
                                                                                          java.util.Random random)

Description copied from interface: ISamplingAlgorithmFactory

After the necessary config is done, this method returns a fully configured instance of a sampling algorithm.

Specified by:

getAlgorithm in interface ISamplingAlgorithmFactory<org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>,OSMAC<org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>>>

Parameters:

sampleSize - Desired size of the sample that will be created.

inputDataset - Dataset where the sample will be drawn from.

random - Random object to make samples reproducible.

Returns:

Configured sampling algorithm object.
