I don't know how often Adobe support/tech staff frequent these pages but I have an idea that will help with facial recognition error rates (which are currently VERY high).
Allow us to add specific data about each person we add. Namely allow us to place a date for each person specifying the first time they would have appeared in our photography. This would ensure their name is not considered for photos of an older timestamp. I arrived at this idea by the simple need to not have my son in the first years of his life (there are many photos!) identified as my daughter who had not even been born yet.
It would also help to be able to state an end date for when a specific person would not appear in photos. The possibilities are extensive if you consider this line of thought.
I hope this idea is noted and (even better) implemented soon.
