Classification metrics.

Metric	Equation
Accuracy (ACC)	$\frac{\text{TPV}+\text{TNV}}{\text{TPV}+\text{TNV}+\text{FNV}+\text{FPV}}$
Precision	$\frac{\text{TPV}}{\text{TPV}+\text{FPV}}$
Recall	$\frac{\text{TPV}}{\text{TPV}+\text{FNV}}$
F1-measure	$2\ast \frac{\text{Precision}.\text{Recall}}{\text{Precision}+\text{Recall}}$
