Use of k=hwc for selecting beta

[KellyWuuu]

Hi! The paper is really great, and thank you for sharing the code here.

I have a quick question about how you calculate k. In the paper, it is said that k = hwc, where h is height, w is width and c is channels. However, when I referred to Appendix C for VGG-16, it seems that k needs to equal 1. Would you mind explaining the calculation of k and its use?

Thanks a lot!

Hi! Thank you for your interest in our paper. Also in the Appendix, k = hwc. In the Appendix C, there is only the Figure 10. How do you got the impression that k=1?

Thank you for your reply!
Maybe I'm making a wrong connection. So, I'm looking at the third column of Figure 10, and the top and bottom heatmaps looked the same. Since the bottleneck is inserted at the same layer, conv4_1, I'm getting a sense that beta = 10 = 10/k.

Using k = hwc makes k an extremely large number; will this make beta too small?
