Hello
Thank you for your amazing job!
According your paper, gamma (in Section 4.2) is the most import parameter. but in your code, I doesn't see it. But in your code, there is the increase_ratio, which doesn't show in your paper. What does the increase_ratio mean?
And what does the Lambda1 and Lambda2 mean? These two doesn't show in your paper and it seems like that these two are only balance the loss1 and loss2. Is that right?
Thank you in advance!
