Simplified non-local block
Webb24 dec. 2024 · Based on this observation, we propose a simplification of the non-local block, which explicitly learns global context other than pairwise relations. The resulting block, called the global context (GC) block, consumes significantly less computation than the non-local block but performs with the same accuracy on several important tasks. WebbA Non-Local Block is an image block module used in neural networks that wraps a non-local operation. We can define a non-local block as: 𝕫 𝕪 𝕚 𝕩 z i = W z y i + x i. where y i is the output from the non-local operation and 𝕩 + x i is a residual connection. Source: Non-local Neural Networks.

WebbBased on this observation, we simplify the non-local block by explicitly using a query-independent attention map for all query positions. Then we add the same aggregated features using this attention map to the features of all query positions for form the output. This simplified block has sig-nificantly smaller computation cost than the ... Webbeither resemble a Transformer block [61] or a Non-Local block [63] (difference highlighted in Figure4). BoTNet is different from architectures such as DETR [10], VideoBERT [55], VILBERT [44], CCNet [34], etc by employing self-attention within the backbone architecture, in contrast to using them outside the backbone architecture.
Webb19 maj 2024 · The simplified non-local is defined as: \begin {aligned} y_i=x_i+W_v\sum _ {j=1}^N \frac {\exp (W_kx_j)} {\sum _ {l=1}^N \exp (W_kx_l)}x_j \end {aligned} (1) where x and y denote the input and output of the simplified non-local block respectively, i and j denote two positions and N is the number of positions in the feature map.
