getAlgorithm

public StratifiedSampling<D> getAlgorithm(int sampleSize,
                                          D 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<D extends org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>,StratifiedSampling<D extends 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.

setPreviousRun

public void setPreviousRun(StratifiedSampling<D> 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<D extends org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>,StratifiedSampling<D extends org.api4.java.ai.ml.core.dataset.supervised.ILabeledDataset<?>>>

Parameters:

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