very simple question.
I have an input [Batch, C_1, H, W],
and want an output [Batch, C_1, H, 1],
and I am going to use a Conv2D with kernel shape (1, W).
However, I only want to use W parameters for this.
If I use the group option I can decrease my weights, and minimally I will have for every channel a set of own weights. However, this gives me C_1 x W weights.
Is there anything better than using a loop or am I blind.
