Accuracy-FLOPs curves of MutualNet and US-Net

[Lutong-Qin]

Dear Author,

I have been reading your paper and aim to apply the proposed Mutualnet in my own research domain. I have several concerns regarding the results obtained in Mutualnet. I am particularly confused by how the performance gap between Mutualnet and USNet varies as the Flops decrease.
For example, Figure 4(a) clearly indicates that as the FLOPs decrease, there is a significant drop in accuracy for USNet, while Mutualnet exhibits a slower decline and shows a considerable advantage. I want to know the performance gap between Mutualnet and USNet would widen or narrow, as the FLOPs decreases. Does it have a clear tendency？According to our understanding, the Mutualnet would behave better at lower computational budget. Is it right?
It will be greatly appreciated if you could provide deep insight into this. Many thanks for your kindly help.
