Question about negative loss #7

Closed CHEN-H01 closed 2 years ago

CHEN-H01 commented 2 years ago

Hi, I am very interested in your work! There's a question that baffles me:

I found that the nll loss is a negative number when training autobots, I wonder if this is a normal phenomenon? Why is nll loss a negative number?

Hi, Thank you for your interest in our work.

Indeed, this is normal behavior. NLL can have negative values when parameterizing Gaussian distributions.

Thanks!

Ohh, thanks! Because I've never seen negative loss can be used to train a model.
