class IRandomBiPartitionSamplingConfig

#include <partition_sampling_bi_random.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 that randomly splits the training examples into two mutually exclusive sets.

Subclassed by RandomBiPartitionSamplingConfig

Public Functions

inline virtual ~IRandomBiPartitionSamplingConfig()

virtual float32 getHoldoutSetSize() const = 0

Returns the fraction of examples that are included in the holdout set.

Returns:

The fraction of examples that are included in the holdout set

virtual IRandomBiPartitionSamplingConfig &setHoldoutSetSize(float32 holdoutSetSize) = 0

Sets the fraction of examples that should be included in the holdout set.

Parameters:

holdoutSetSize – The fraction of examples that should be included in the holdout set, e.g. a value of 0.6 corresponds to 60 % of the available examples. Must be in (0, 1)

Returns:

A reference to an object of type IRandomBiPartitionSamplingConfig that allows further configuration of the method for partitioning the available training examples into a training set and a holdout set

class RandomBiPartitionSamplingConfig : public IPartitionSamplingConfig, public IRandomBiPartitionSamplingConfig

#include <partition_sampling_bi_random.hpp>

Allows to configure a method for partitioning the available training examples into a training set and a holdout set that randomly splits the training examples into two mutually exclusive sets.

Public Functions

RandomBiPartitionSamplingConfig()

virtual float32 getHoldoutSetSize() const override

Returns the fraction of examples that are included in the holdout set.

Returns:

The fraction of examples that are included in the holdout set

virtual IRandomBiPartitionSamplingConfig &setHoldoutSetSize(float32 holdoutSetSize) override

Sets the fraction of examples that should be included in the holdout set.

Parameters:

holdoutSetSize – The fraction of examples that should be included in the holdout set, e.g. a value of 0.6 corresponds to 60 % of the available examples. Must be in (0, 1)

Returns:

A reference to an object of type IRandomBiPartitionSamplingConfig that allows further configuration of the method for partitioning the available training examples into a training set and a holdout set

virtual std::unique_ptr<IPartitionSamplingFactory> createPartitionSamplingFactory() const override

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
