Yolov9 bad results

[alperemir]

Hello, as you suggested, I balanced the classes and performed the training again and I share the results as below. In the tests I have done, the new model results become worse when gloves and glasses are added. How can I solve this problem?

-old model

-new model

Thanks for your support.

Hello, this seems to be the problem with model, we do not heave the context - your message suggest that you were given some instructions from Roboflow - could you specify where? Maybe you could follow up with that specific person
