HTER consistency in metrics
Several metrics and plots report HTER but I am not sure it is calculated the same way in all cases.
bob measure metrics and
bob measure epc both report HTER. However, I don't think they are calculated the same way.
What should be HTER anyway @bob? at least in biometrics, we have FMR, FNMR, FAR, and FRR.
HTER = (FMR+FNMR)/2 or
HTER = (FAR+FRR)/2?
FAR = FMR * (1 - FTA) FRR = FTA + FNMR * (1 - FTA)
