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.

I need help to improve it and all the steps, like –
How is CNN helpful here ?
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.
Any help, advice or suggestions.

This is my first Research Project, who please answer everything in Details, I am still learning. 0_0
