Add performance metrics

[NilsB98]

Use F1-Score, Accuracy etc. to evaluate the performance of the model.

which .py is used for evaluation metric? Thank you for your help

[NilsB98]

Hi @Henry0528, currently this is not implemented and will probably be realized via a function in the utils, which can then be used within the training (main.py) script as well as the inference scripts.
But I'll implement this soon.

ok, I'm looking forward to your future update!
