I am researching methods to make an attendance system, where the professor clicks few photos (2 to 3)
and upload on app where automatic attendance is given for about 80 students. I am limited training Data, which is the biggest drawback and major issue we need to counter. I made a basic model that trains and marks attendance.

How do I train it to work like a Reward Punishment system where I can manually tell it who the person is it wasn’t able to recognize so it learns on the way.
