Adv Loss is not supported by the paper???

[xljhtq]

Hi, I want to know where the adv loss is different from the domain loss??
In another word, the adv loss in the paper "Adversarial Multi-task Learning for Text Classification" has not described clearly. So i want to know what the equation is??

[FrankWork]

total_loss = task_loss + adv_loss + diff_loss + l2_loss

@FrankWork In your code, "total_loss = task_loss + adv_loss + diff_loss + l2_loss" , to minimize the total_loss, then the adv_loss will be decreasing. But in reality, we should let adv_loss increase in order to get the shared feature.
So what I should do to maximize the adv_loss or minimize the adv_loss ???

[FrankWork]

there is a function flip_gradient to maximize the adv_loss

Hi, do you know equivalent function of flip_gradient in pytorch
