Confusion about asymmetricSmoothLoss

[alexzzhu]

I'm a little confused about the workings of the asymmetricSmoothLoss function. It looks like you compute smoothness losses for the valid (nonOccSmooth) and invalid sections (occSmooth) separately. However, at the end of the function, the sum of the losses is multiplied by the corrected valid mask. Doesn't this essentially eliminate the occSmooth losses? From my initial reading, it seems like the correct output of the function should be nonOccSmooth + (1.-valid) * occSmooth.
