Label smooth cross
WebLabel smoothing (Szegedy et al.,2016;Pereyra et al.,2024;Muller et al.¨ ,2024) is a simple means of correcting this in classification settings. Smooth-ing involves simply adding a small reward to all possible incorrect labels, i.e., mixing the standard one-hot label with a uniform distribution over all labels. This regularizes the training ... Web@staticmethod def logging_outputs_can_be_summed ()-> bool: """ Whether the logging outputs returned by `forward` can be summed across workers prior to calling …
