SaigeClassRoc

• #include <SaigeVisionAPI.h>

ROC curve and AUROC of a single class, computed during validation at training time.

The lengths of fpr, tpr, and threshold are identical (numPoints), but may differ across classes. For SEG models these are pixel-level metrics.

Public Attributes

Type	Name
int	classIndex Class index this ROC belongs to, matching SaigeModelInfo::classNames. Note that classes without a metric (e.g. the OK class of SEG) are omitted, so indices may be non-contiguous.
float	auroc Area under the ROC curve.
int	numPoints Number of points in the fpr, tpr, and threshold arrays.
const float *	fpr False positive rates, length numPoints.
const float *	tpr True positive rates, length numPoints.
const float *	threshold Thresholds, length numPoints.
