filter sizes

[JohannesBrand]

Hi,

Thank you a lot for sharing the code for your paper. It's really helpful.

I understand that the downward stream covers the vertical dependencies (i.e. vertical stack from the van den Oord paper), but I'm not sure how the downward + right stream works: If I'm correct, the downward + right stream uses filter_size [2,2] between res blocks. Why is the vertical part needed? would a filter_size [1,2] not cover all the horizontal dependencies?

and does the padded channel of ones from the beginning act like a bias term?

Thank you
