bias in bbox #2

Open xarryon opened 1 year ago

xarryon commented 1 year ago

Thanks for this new deepfake detection work! I tested this project and find the bboxes may bring biases during generation. Does this phenomenon may harm the performance? image

It may increase the bounding box regression loss during the training phase. In my experiments, such high regression loss will limit the softmax loss convergence. So I think It may harm the model performance, please check your code and fix this bug~

Actually I just use the code from CADDM without much changes, have you ever encounter this phenomenon?
