Academic Guide:Age and Gender detection for thesis

[Ninja At Work]

Hi all
I'm going to choose the age and gender detection field for my AI master thesis.

There's one model in the zoo from the openu.ac.il students (more detail):
" Age/Gender.net are models for age and gender classification trained on the Adience-OUI dataset. See the Project page. "

please help me about how to increase accuracy or performance?
by improving the current algorithm
or new network layer composite/design
or any creative idea to do with dataset(else replacing with Resnet)

(also I'll be very excited if you are a PhD. graduate/student and can guide me a little to narrow the research)
any help would be appreciated

-thanks
