Confused by the loss function.

[JinYang88]

In your code, you minimized -(oloss + nloss).mean()

which means (oloss+nloss) should be large.
So, "oloss become large and nloss become small " is expected.

Although -(oloss+nloss) decrease, I got oloss become small and nloss become large, how so?

Thank you for the feedback.
Can you provide a reduced, reproducible case sample? Like, small dataset and a configuration for it.

When computing nloss, the author uses function .neg to make the nloss smaller when training.
