CBAM: sequential channel and spatial feature attention

Contribution grade

Convolutional visual recognition · Human-designed research method or resource

Reference score125,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Combined shared-MLP channel attention using average/max pooling with a subsequent spatial-attention map, providing a plug-in convolutional feature-refinement module.

Scientific scope

Combined shared-MLP channel attention using average/max pooling with a subsequent spatial-attention map, providing a plug-in convolutional feature-refinement module. Extends channel attention and prior spatial gating rather than inventing all neural attention. Sequential channel-then-spatial gating is distinct from SE-only recalibration and token-pair self-attention. Lightweight overhead and accuracy improvements are benchmark-dependent. General visual recognition work is in scope despite one author's company affiliation.
