Question about code.

[Fay-why]

hi~ Thanks for your clear codes. I have two questions and hope for you to reply. 1.why Line 58 above multiply the (batch_size * (pos_size + neg_size))?? In your paper, this item didn't show up. 2. I saw a lot of mask in your codes, but I'm not much clear about the meaning of mask.
