Question about position encoding in Relationshipness(nn.Module)

[mandal4]

Thank you for a nice work!

I found that there is pos_encoding argument in class Relationshipness (relationshipness.py)
I guess it is to regress each relationshipness with considering geometric location of each box.
But i found any expression about it in the paper.
Did you use pos_encoding to report the experimental result?

Thanks,
