External_attention in the code is strange, only do attention on channel, but no attention on pixel.

M is a set of "pattern" feature vectors (#vector = S), not feature vectors of pixels.
Conv1d.weight can be viewed as M, #out channel = S, # in channel = d.
Therefore the result of Conv1d will be the dot product between feature vectors of pixels and M's rows(shape of M = S × d = out × in, out channels ↔ rows).
k in code = S in paper, c in code = d in paper.
等一下，为什么你要用英文提问，作者也是**人啊。

ok, I get it.
谢谢你还先用英文回答🤣
