Attention gate (AG). The gating signal g is obtained from a coarse feature map in the decoder, which provides information to disambiguate irrelevant information in the low-level feature map x in the encoder. The concatenated features x and g are linearly mapped to a \(F_i\)-dimensional intermediate space. The attention mask \(\theta\) guides the attention gate to capture only the important information \({\hat{x}}\)
