In this article we will cover one of the most influential attention mechanisms proposed in computer vision: channel attention, as seen in Squeeze-and-Excitat…
At last, we use feature transform block to explore the channel-wise interdependencies. The output of high-level feature xˆh∈RC×H×W is obtained as: (6)xˆh=Relu(Bbn(Lln(δ)⊗xh′)) Here, Lln(⋅) represents a LayerNorm, Bbn(⋅) is batch normalization, Relu(⋅) is ...

Linear codes are algebraic codes, typically over a finite field, where the (symbol-wise) sum of two codewords is always a codeword and the (symbol-wise) multiplication of a codeword by a field element is also a codeword. Linear codes that are also block codes are linear block codes. ...
(6), and * is an element-wise multiplication procedure between Gℓ,a2 and each two-dimensional filter of Qi,ξ. Qi,ℓa is the regulated filter of Qi,ξ by the a- scaled Gabor filter Gℓ,a. Then a Gabor oriented filter (GoF) is defined as:(21)Cia=Ci,1a,Ci,2a,…,Ci,Ua....
It is worth highlighting some obvious similarities between the pairwise error probability and the diversity-multiplexing trade-off in correlated Rayleigh slow fading channels at both infinite and finite SNR (see Section 5.9). In the high SNR regime, the diversity-multiplexing trade off remains unaffec...
where ⊗⊗ denotes channel-wise multiplication, and 𝑌𝑖Yi refers to the feature map weighted by the multi-scale channel attention weight vector, which has stronger feature representation and modeling capability, The concatenation operator is more efficient than the summation operator because it ...
𝑊𝑖∈𝑅3×𝐶×𝐶Wi∈R3×C×C denotes the weights of the dilated convolution with kernel size 3, C input channels and C output channels, 𝑏𝑖bi is bias vector of the ith dilated convolutional layer, ⊙ is the element-wise multiplication operator and 𝜎σ is the sigmoid activa...
The operation ⊙⊙ represents element-wise multiplication across different dimensions of the kernel space. The operation ∗∗ denotes convolution. Figure 7. Structure of the ODConv. Building on the concepts introduced for SlimNeck and ODConv, we aimed to both reduce the inference speed and ...
