class IBoostingStatistics : public virtual IStatistics¶
- #include <statistics.hpp>
Defines an interface for all classes that provide access to gradients and Hessians which serve as the basis for learning a new boosted rule or refining an existing one.
Subclassed by boosting::IDecomposableStatistics< RuleEvaluationFactory >, boosting::INonDecomposableStatistics< NonDecomposableRuleEvaluationFactory, DecomposableRuleEvaluationFactory >
Public Types
-
template<typename ScoreType>
using DenseScoreMatrixVisitor = std::function<void(const CContiguousView<ScoreType>&)>¶ A visitor function for handling score matrices of the type
CContiguousView.
-
template<typename ScoreType>
using SparseScoreMatrixVisitor = std::function<void(const SparseSetView<ScoreType>&)>¶ A visitor function for handling score matrices of the type
SparseSetView.

inline virtual ~IBoostingStatistics()¶
-
virtual void visitScoreMatrix(DenseScoreMatrixVisitor<float32> dense32BitVisitor, DenseScoreMatrixVisitor<float64> dense64BitVisitor, SparseScoreMatrixVisitor<float32> sparse32BitVisitor, SparseScoreMatrixVisitor<float64> sparse64BitVisitor) const = 0¶
Invokes one of the given visitor functions, depending on which one is able to handle the type of matrix that is used to store the currently predicted scores.
- Parameters:
dense32BitVisitor – The visitor function for handling objects of the type
CContiguousView<float32>dense64BitVisitor – The visitor function for handling objects of the type
CContiguousView<float64>sparse32BitVisitor – The visitor function for handling objects of the type
SparseSetView<float32>sparse64BitVisitor – The visitor function for handling objects of the type
SparseSetView<float64>
