The reported numbers are higher than DELG paper

[Jeff-Zilence]

Thank you so much for the nice repo. I notice that the performance of DELG (ResNet50 Global) is around 73 on ROxf M. But this repo claims to have 78.51, which is much higher. Do you have any idea about this performance gap? Could you highlight the key implementation differences that might cause this performance gap? Thank you for your time and consideration. Looking forward to hearing from you.
