Channel attention (such as SE and ECA) learns which feature channels are important, outputs a channel-dimensional weight vector, and shares it across all spatial positions; spatial attention (such as the CBAM spatial branch and Non-local) learns which positions are important, outputs a spatial weight map, and shares it across all channels.
