**TLDR:** A CNN module that reweights feature channels using global context.

<p>Squeeze-and-Excitation blocks enable CNNs to dynamically adjust channel importance depending on the input example. First, a global summary is computed, then the model learns how strongly each channel should be emphasized. Because it can yield strong performance gains with relatively small overhead, it has been integrated into many modern architectures. It is one of the most successful forms of channel attention.</p>
