Why use "CAddTable" instead of concatenating features in the memory network?

Hi Visdial Team,

I have a question regarding to combining the history and question features in the memory network encoder. Why do you use element add instead of simply concatenating like you did in the late fusion encoder? Is there any advantages in this?

Thank you in advance!

Best,
Rui

To be as close to the Memory Networks paper as possible. We haven't tried concatenating. Let us know how things go if you do :)
