Grouped convolution is a convolution technique whereby the standard convolution is applied separately to an input matrix diced into equal parts along the channel axis. As shown in Figure 7 , the input is divided into equal parts along the channel axis, and group convolution is then applied separately.

Convolution reverb does indeed use mathematical convolution as seen here! First, an impulse, which is just one tiny blip, is played through a speaker into a space (like a cathedral or concert hall) so it echoes. (In fact, an impulse is pretty much just the Dirac delta equation through a speaker!)The core unit of MobileNet is depth-wise separable convolution, which is an operation that decomposes a standard convolution into two parts: depth-wise convolution and point-wise convolution, as shown in Table 2.1.
