Constructor Detail

ParameterTuningHelper

public ParameterTuningHelper(IExperimentFactory<T> experimentFactory,
                             int numFolds,
                             List<List<Double>> parameters,
                             int timeoutSeconds,
                             int numThreads)

Method Detail

splitData

protected List<List<T>> splitData(Iterable<T> data,
                                  int dataSize)

Splits the data into numFolds parts.

Note: This splits the data into K folds uniformly. If the classes are not equally distributed, then this is wrong. Instead, override this to do a stratified split, so that the split proportions are maintained.

tune

public List<Double> tune(Iterable<T> data,
                         int dataSize)
                  throws InterruptedException,
                         ExecutionException

Throws:

InterruptedException

ExecutionException
