Question about loss calculation in AR model without handling mask #185

Open hertz-pj opened 6 months ago

hertz-pj commented 6 months ago

Regarding the loss calculation part of the AR model, why isn't the mask being handled?

total_loss = F.cross_entropy(logits, targets, reduction=reduction)

Normally, shouldn't it be:

total_loss = F.cross_entropy(logits.mask_selected(y_mask), targets.mask_selected(y_mask), reduction=reduction)

What's the reason for not considering the mask?

Hi, Did you understand why there is no mask in the ar loss?
