Dear author team,
Nice to meet you.
Here comes a terrible problem, our team tested your model as a comparative experiment, but after 25 epochs in the dataset you named PB, we attained persistent auc 0.500 in the following long run. We trapped into the same dilemma in our own dataset ,too.
Below we attach the screenshot. We need your help, thanks!
