Incrementally adding new faces

[sferaud]

Hi,

I've implemented a solution with yolo3 borrowing some things from your contribution.
I can detect various faces, but training is proving a bit slow for my requirements.
Would it be possible to incrementally add new faces? Meaning, just train the new face on top of the previous weights, so as not to train the model for all classes from scratch every time a new face appears.

Any input on this would be appreciated.
