Functions

std::unique_ptr<ICsrLabelMatrix> createCsrLabelMatrix(uint32 *indices, uint32 *indptr, uint32 numRows, uint32 numCols)

Creates and returns a new object of the type ICsrLabelMatrix.

Parameters:

  • indices – A pointer to an array of type uint32, shape (numDenseElements), that stores the column indices of all dense elements explicitly stored in the matrix

  • indptr – A pointer to an array of type uint32, shape (numRows + 1), that stores the indices of the first element in indices that corresponds to a certain row. The index at the last position is equal to numDenseElements

  • numRows – The number of rows in the label matrix

  • numCols – The number of columns in the label matrix

Returns:

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

class ICsrLabelMatrix : public virtual IRowWiseLabelMatrix
#include <label_matrix_csr.hpp>

Defines an interface for all label matrices that provide row-wise access to the labels of individual examples that are stored in a sparse matrix in the compressed sparse row (CSR) format.
