WebThe EER is the point where the FAR is equal to FRR. The lower is the EER, the better is the system in the average case. The EER can be calculated from the DET curve, which plots the false rejection rate vs. the false acceptance rate, as being the point that crosses the curve or the closest point to the perfect one.

WebDET curve （2）matlab. Draw a DET curve is usually drawn in a normal deviation scale, so data scale transformation is required before drawing. Refer to the implementation of metrics.detcurvedisplay (fpr = fpr_det, fnr = fnr_det) in Sklearn, you can see that several key transformation steps are as follows: WebAxis warping. The normal deviate mapping (or normal quantile function, or inverse normal cumulative distribution) is given by the probit function, so that the horizontal axis is x = probit(P fa) and the vertical is y = probit(P fr), where P fa and P fr are the false-accept and false-reject rates..
