class IPartitionSampling

#include <partition_sampling.hpp>

Defines an interface for all classes that implement a method for partitioning the available training examples into a training set and a holdout set.

Public Functions

inline virtual ~IPartitionSampling()

virtual IPartition &partition(RNG &rng) = 0

Creates and returns a partition of the available training examples.

Parameters:

rng – A reference to an object of type RNG, implementing the random number generator to be used

Returns:

A reference to an object of type IPartition that provides access to the indices of the training examples that belong to the training set and holdout set, respectively

class IPartitionSamplingFactory

#include <partition_sampling.hpp>

Defines an interface for all factories that allow to create objects of type IPartitionSampling.

Public Functions

inline virtual ~IPartitionSamplingFactory()

virtual std::unique_ptr<IPartitionSampling> create(const CContiguousView<const uint8> &labelMatrix) const = 0

Creates and returns a new object of type IPartitionSampling.

Parameters:

labelMatrix – A reference to an object of type CContiguousView that provides random access to the labels of the training examples

Returns:

An unique pointer to an object of type IPartitionSampling that has been created

virtual std::unique_ptr<IPartitionSampling> create(const BinaryCsrView &labelMatrix) const = 0

Creates and returns a new object of type IPartitionSampling.

Parameters:

labelMatrix – A reference to an object of type BinaryCsrView that provides row-wise access to the labels of the training examples

Returns:

An unique pointer to an object of type IPartitionSampling that has been created

class IPartitionSamplingConfig

#include <partition_sampling.hpp>

Defines an interface for all classes that allow to configure a method for partitioning the available training examples into a training set and a holdout set.

Subclassed by ExampleWiseStratifiedBiPartitionSamplingConfig, LabelWiseStratifiedBiPartitionSamplingConfig, NoPartitionSamplingConfig, RandomBiPartitionSamplingConfig

Public Functions

inline virtual ~IPartitionSamplingConfig()

virtual std::unique_ptr<IPartitionSamplingFactory> createPartitionSamplingFactory() const = 0

Creates and returns a new object of type IPartitionSamplingFactory according to the specified configuration.

Returns:

An unique pointer to an object of type IPartitionSamplingFactory that has been created
