Option to invert the sign of the scores in ./bin/evaluate.py script
This issue was raised in the bob-devel group.
The script evaluate.py expects that the genuine scores are higher than the impostor scores. However, if you work with similarity measures, where the expectation is to have genuine scores lower than the impostors, this script will not work properly.
Would be nice to have an option in this script that just multiplies the scores by -1 if activated
