Fig. 4: Overview of the proposed Bi-correlational attention module (BCAM).
From: DuaL-branch similarity network with Bi-correlative attention for few-shot Shui script recognition
BCAM module consists of Cross-Correlational Attention (CCA) module and Self-Correlational Attention (SCA) module. fc indicates cross-correlational attention map, and fs indicates self-correlational attention map. C multiplies fc and fs with \({Z}_{S}^{{\prime} }\) and \({Z}_{Q}^{{\prime} }\) respectively and concatenates them along the channel dimension.
