class NonDecomposableCompleteRuleEvaluationFactory : public boosting::INonDecomposableRuleEvaluationFactory
#include <rule_evaluation_non_decomposable_complete.hpp>

Allows to create instances of the class INonDecomposableRuleEvaluationFactory that allow to calculate the predictions of complete rules, which predict for all available outputs.

Public Functions

NonDecomposableCompleteRuleEvaluationFactory(float64 l1RegularizationWeight, float64 l2RegularizationWeight, const Blas &blas, const Lapack &lapack)
Parameters:

  • l1RegularizationWeight – The weight of the L1 regularization that is applied for calculating the scores to be predicted by rules

  • l2RegularizationWeight – The weight of the L2 regularization that is applied for calculating the scores to be predicted by rules

  • blas – A reference to an object of type Blas that allows to execute BLAS routines

  • lapack – An reference to an object of type Lapack that allows to execute BLAS routines

virtual std::unique_ptr<IRuleEvaluation<DenseNonDecomposableStatisticVector>> create(const DenseNonDecomposableStatisticVector &statisticVector, const CompleteIndexVector &indexVector) const override

Creates and returns a new object of type IRuleEvaluation that allows to calculate the predictions of rules that predict for all available outputs, based on the gradients and Hessians that are stored by a DenseNonDecomposableStatisticVector.

Parameters:

  • statisticVector – A reference to an object of type DenseNonDecomposableStatisticVector. This vector is only used to identify the function that is able to deal with this particular type of vector via function overloading

  • indexVector – A reference to an object of type CompleteIndexVector that provides access to the indices of the outputs for which the rules may predict

Returns:

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

virtual std::unique_ptr<IRuleEvaluation<DenseNonDecomposableStatisticVector>> create(const DenseNonDecomposableStatisticVector &statisticVector, const PartialIndexVector &indexVector) const override

Creates and returns a new object of type IRuleEvaluation that allows to calculate the predictions of rules that predict for a subset of the available outputs, based on the gradients and Hessians that are stored by a DenseNonDecomposableStatisticVector.

Parameters:

  • statisticVector – A reference to an object of type DenseNonDecomposableStatisticVector. This vector is only used to identify the function that is able to deal with this particular type of vector via function overloading

  • indexVector – A reference to an object of type PartialIndexVector that provides access to the indices of the outputs for which the rules may predict

Returns:

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