GCT first collects global information by computing the l2-norm of each channel. Next, a learnable vector α is applied to scale the feature. Then a competition mechanism is adopted by channel normalization to interact between channels.

Unlike previous methods, GCT first collects global information by computing the l₂-norm of each channel. Next, a learnable vector α is applied to scale the feature. Then a competition mechanism is adopted by channel normalization to interact between channels. Like other common normalization methods, a learnable scale parameter γ and bias β are applied to rescale the normalization. However, unlike previous methods, GCT adopts tanh activation to control the attention vector. Finally, it not only multiplies the input by the attention vector but also adds an identity connection. GCT can be written as: s = F_(gct)(X, θ) = tanh(γCN(αNorm(X)) + β) Y = s X + X

where α, β and γ are trainable parameters. Norm(·) indicates the L2-norm of each channel. CN is channel normalization.

A GCT block has fewer parameters than an SE block, and as it is lightweight, can be added after each convolutional layer of a CNN.

Papers per year the archive tags with this method, by the paper's archive date (8 dated). Bars are counts, not a trend claim.

Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
