Some concerns: 1. There is too much-overleaped information in Table 1, Table 2, and Figure 1. Figure 1 includes all information presented in Tables 1 and 2. 2. What’s the logic between the proposed method and [9] and [16]? Why the authors compare the proposed method with [9] first, then [16]? Why the authors only compare the computational cost with [9], but [16]? Is the computational cost a big contribution to this paper? Is that a big issue in a practical scenario? That part is weird to me and there is no further discussion about it in the rest of this paper. 3. Why the proposed column smoothing method produces better result compare with block smoothing method? 4. The accuracy drop for the Imagenet dataset is a concern, which makes the proposed method in-practical.
