Class GroupedRandomisedPercentageHoldOut<KEY,INSTANCE>

java.lang.Object

org.openimaj.experiment.validation.DefaultValidationData<org.openimaj.data.dataset.GroupedDataset<KEY,org.openimaj.data.dataset.ListDataset<INSTANCE>,INSTANCE>>

org.openimaj.experiment.validation.GroupedRandomisedPercentageHoldOut<KEY,INSTANCE>

Type Parameters:

KEY - Type of groups

INSTANCE - Type of the instances in the dataset

All Implemented Interfaces:

TrainSplitProvider<org.openimaj.data.dataset.GroupedDataset<KEY,org.openimaj.data.dataset.ListDataset<INSTANCE>,INSTANCE>>, ValidateSplitProvider<org.openimaj.data.dataset.GroupedDataset<KEY,org.openimaj.data.dataset.ListDataset<INSTANCE>,INSTANCE>>, ValidationData<org.openimaj.data.dataset.GroupedDataset<KEY,org.openimaj.data.dataset.ListDataset<INSTANCE>,INSTANCE>>

public class GroupedRandomisedPercentageHoldOut<KEY,INSTANCE>
extends DefaultValidationData<org.openimaj.data.dataset.GroupedDataset<KEY,org.openimaj.data.dataset.ListDataset<INSTANCE>,INSTANCE>>

Hold-Out validation for grouped data that selects a percentage of the original data to use for training, and the remainder to use for validation. No attempt is made to ensure that the distribution of relative group sizes is constant. If this is important, use a StratifiedGroupedRandomisedPercentageHoldOut instead.
