WebPost concatenation, similar to ShuffleNet v2, a channel shuffle strategy is adopted to enable cross-group information flow along the channel dimension. Thus the final output is of the same dimension as that of the input tensor to the SA layer. Code. The following code snippet provides the structural definition of the SA layer in PyTorch.
