**TLDR:** An efficient convolution structure that reduces CNN computation by separating spatial and channel transformations.

<p>Depthwise separable convolution reduces computational burden significantly by splitting standard convolution into two stages. First, a spatial filter is applied separately to each channel; then cross-channel information is combined through pointwise convolution. It is a core building block of efficient CNN designs for mobile and embedded systems. It offers a strong balance between parameter efficiency and performance.</p>
