Common Measure in Face Verification
In face verification task, we have several metrics to measure model performances. Verification Rate (FR) under False Acceptance Rate First, we need to understand the false acceptance rate. There is a table showing reality and prediction. false acceptance rate is defined as “the percentage of identification instances, in which unauthorised cases are incorrectly accepted”. $$ FAR = \frac{FA}{FT} = \frac{False_Negative}{False_Negative+True_Negative} $$ Verification rate is the accuracy of a verification model....
