for variable variable_idx as printed by printMachineReadableConfusionMatrices

The first entry is the name of the variable. The second entry is the value of variable_idx, The entry (r*numCols+c)+2 where r and c are both in 0..nv-1, nv being the number of values that the variable takes on, is the entry at row r and column c of *pMatrix

Parameters

variable_idx	the index of the variable in the relation
pRelation	a pointer to the relation from which the variable_idx-'th variable is taken. Cannot be NULL.
pMatrix	a pointer to the confusion matrix. (*pMatrix)[r][c] is the number of times that r was expected and c was received. Cannot be NULL.

static std::string GClasses::GLearnerLib::machineReadableConfusionHeader	(	std::size_t	variable_idx,
		const GRelation *	pRelation
	)

static

Returns the header for the machine readable confusion matrix for variable variable_idx as printed by printMachineReadableConfusionMatrices.

The header is comma-separated values. The first two entries in the header are "Variable Name","Variable Index". The rest of the entries fit the format "Expected:xxx/Got:yyy" where xxx and yyy are two values that the variable can take on.

Parameters

variable_idx	the index of the variable in the relation
pRelation	a pointer to the relation from which the variable_idx-'th variable is taken. Cannot be null

	)

static

static void GClasses::GLearnerLib::printMachineReadableConfusionMatrices	(	const GRelation *	pRelation,
		vector< GMatrix * > &	matrixArray
	)

static

Prints the confusion matrices as machine-readable csv-like lines.

The first line is a header giving the names of the columns for the next line. The first column is the name of the label variable for which the matrix is being printed. The rest of the columns are the names of the expected/got values (row/column in the input matrices)

Parameters

pRelation	the relation for which the confusion matrices are given. Cannot be NULL.
matrixArray	matrixArray[i] is null if there is no matrix to be printed. Otherwise matrixArray[i] is the confusion matrix for the i'th attribute of pRelation. Row r, column c of matrixArray[i] is the number of times the value r of the attribute was expected and c was encountered.
