class IInstanceSamplingWithReplacementConfig

#include <instance_sampling_with_replacement.hpp>

Defines an interface for all classes that allow to configure a method for selecting a subset of the available training examples with replacement.

Subclassed by InstanceSamplingWithReplacementConfig

Public Functions

inline virtual ~IInstanceSamplingWithReplacementConfig()

virtual float32 getSampleSize() const = 0

Returns the fraction of examples that are included in a sample.

Returns:

The fraction of examples that are included in a sample

virtual IInstanceSamplingWithReplacementConfig &setSampleSize(float32 sampleSize) = 0

Sets the fraction of examples that should be included in a sample.

Parameters:

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

Returns:

A reference to an object of type IInstanceSamplingWithoutReplacementConfig that allows further configuration of the method for sampling instances

class InstanceSamplingWithReplacementConfig : public IInstanceSamplingConfig, public IInstanceSamplingWithReplacementConfig

#include <instance_sampling_with_replacement.hpp>
