Question about the Figure 5 (CA visualization) in paper

[Lecanyu]

Hi, I'm interested about the Figure 5, Visualization of internal feature maps with their channel attentions, in your paper.

Could you please tell me more details about how you calculate the activation maps for channels? Or pubilish the relevant code about the activation map calculation.

Thanks

Sorry for the late reply.
From what I remember, I simply grabbed the channel with the highest channel attention score for each Residual Group and displayed it as a heatmap (don't exactly remember the color coding of the heatmap, though).

For instance, for ResGroup1, there are 12 ResBlocks and 128 channels, so 128*12 attention scores in total. I just took the one with the maximum attention score. Same for the other Groups.
