depthwise separable convolutions or group convolutions into the building blocks to strike an excellent trade-off between representation capability and computational cost. However, we notice that both designs do not fully take the 1 convolutions (also called pointwise convolutions in [12]) into account, which require considerable complex-ity.

Depthwise separable convolutions, which our proposed architecture is entirely based upon. While the use of spa-tially separable convolutions in neural networks has a long history, going back to at least 2012 [12] (but likely even earlier), the depthwise version is more recent.

The L-point circular convolution of x1[n] and x2[n] is shown in OSB Figure 8.18(e), which can be formed by summing (b), (c), and (d) in the interval 0 ≤ n ≤ L − 1. Since the length of the linear convolution is (2L-1), the result of the 2L-point circular con­ volution in OSB Figure 8.18(f) is identical to the result of linear convolution.
