about accuracy

[shenhaibb]

I use res50-C5
when I don't use the pre-training model, the accuracy is only 59%. After using the pre-training model, the accuracy reaches 80%.
However, my experiment on YOLOv5s is only 75%.
Should I use the pre-training model? What may be the reason for my situation?

Yes, it is better to use the pre-trained model given performance and training time. We suggest you to read this paper for a deeper understanding.
