What's the meaning of logit_laplace_eps here since both the input and output are [0,1] tensors.

DALL-E/dall_e/utils.py

Line 51 in 5be4b23

return (1 - 2 * logit_laplace_eps) * x + logit_laplace_eps

See page 13 of the paper (https://arxiv.org/pdf/2102.12092.pdf#page=13):

It takes a [0,1] tensor as input and outputs an [0.1,0.9] tensor.
