File label_sampling.hpp¶

class ILabelSampling¶

#include <label_sampling.hpp>

Defines an interface for all classes that implement a method for sampling labels.

Public Functions

virtual const IIndexVector &sample(RNG &rng) = 0¶

Creates and returns a sample of the available labels.

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 IIndexVector that provides access to the indices of the labels that are contained in the sample

class ILabelSamplingFactory¶

#include <label_sampling.hpp>

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

Public Functions

virtual std::unique_ptr<ILabelSampling> create() const = 0¶

Creates and returns a new object of type ILabelSampling.

Returns:: An unique pointer to an object of type ILabelSampling that has been created

class ILabelSamplingConfig¶

#include <label_sampling.hpp>

Defines an interface for all classes that allow to configure a method for sampling labels.

Public Functions

virtual std::unique_ptr<ILabelSamplingFactory> createLabelSamplingFactory(const ILabelMatrix &labelMatrix) const = 0¶

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

Parameters:: labelMatrix – A reference to an object of type ILabelMatrix that provides access to the labels of the training examples
Returns:: An unique pointer to an object of type ILabelSamplingFactory that has been created
