Question about loss

Minglin-Chen opened this issue · comments

Hi, I realize that you use Chamfer loss here which always has a positive value. However, the loss curve shown in figure here has a negative value. That really confuses me.

I want to know whether the loss used in the figure is Chamfer loss or other loss?

Hi,
It's because we plot the log of the chamfer distance. It helps to see when the network has converged.
Let me know if you have more feedback / question.
Best regards,
Thibault

Thanks, Thibault. It is clear for me.
