Question about the mask in code

[handsomelys]

I would like to ask, what do triplet masks and other masks in the code do? Looking forward to your answer!

As said in the paper:

During training, there may exist some false negatives. 
For example, the correct entity happens to appear in another triple within the same batch. 
We filter out such entities with a binary mask.

If a <h, r, t> triple is true according to the training data, we do not consider t as a negative. We use a mask to implement this mechanism.
