class DenseCoverageMatrix : public DenseMatrixDecorator<AllocatedCContiguousView<uint32>>
#include <matrix_coverage_dense.hpp>

A two-dimensional matrix that stores how often individual examples and labels have been covered in a C-contiguous array.

Public Functions

DenseCoverageMatrix(uint32 numRows, uint32 numCols, float64 sumOfUncoveredWeights)
Parameters:

  • numRows – The number of rows in the matrix

  • numCols – The number of columns in the matrix

  • sumOfUncoveredWeights – The sum of the weights of all examples and labels that have not been covered yet

float64 getSumOfUncoveredWeights() const

Returns the sum of the weights of all examples and labels that have not been covered yet.

Returns:

The sum of the weights of all examples and labels that have not been covered yet

void increaseCoverage(uint32 row, View<uint32>::const_iterator majorityLabelIndicesBegin, View<uint32>::const_iterator majorityLabelIndicesEnd, View<float64>::const_iterator predictionBegin, View<float64>::const_iterator predictionEnd, CompleteIndexVector::const_iterator indicesBegin, CompleteIndexVector::const_iterator indicesEnd)

Increases the number of times the elements at a specific row of this matrix are covered, given the predictions of a rule that predicts for all available labels.

Parameters:

  • row – The row

  • majorityLabelIndicesBegin – An iterator to the beginning of the indices of the labels that are relevant to the majority of the training examples

  • majorityLabelIndicesEnd – An iterator to the end of the indices of the labels that are relevant to the majority of the training examples

  • predictionBegin – An iterator to the beginning of the predictions

  • predictionEnd – An iterator to the end of the predictions

  • indicesBegin – An iterator to the beginning of the label indices

  • indicesEnd – An iterator to the end of the label indices

Increases the number of times the elements at a specific row of this matrix are covered, given the predictions of a rule that predicts for a subset of the available labels.

Parameters:
