How to determine the width parameter

drcege opened this issue · 1 comments

May I ask how to determine the width parameter w?

For example in Table 3, Res2Net-50 (Preserved complexity) of settings 48wx2s, 26w×4s, and 14w×8s have the same FLOPs as ResNet-50 of 64w.
How did you get the values 48, 26, and 14? Can you share the calculation formula?

We adjuct the width of models with each scale to make the overall parameters and FLOPS constant with resnet-50. It's easy to keep the Flops as the overall structure is not changed.
