WebHere, we propose a novel Attention Graph Convolution Network (AGCN) to perform superpixel-wise segmentation in big SAR imagery data. AGCN consists of an attention mechanism layer and Graph Convolution Networks (GCN). GCN can operate on graph-structure data by generalizing convolutions to the graph domain and have been … WebMar 20, 2024 · The attention mechanism gives more weight to the relevant and less weight to the less relevant parts. This consequently allows the model to make more accurate …
WebJan 1, 2024 · Graph attention networks (GATs) [18] utilized the attention mechanisms to assign aggregation weights to neighboring nodes. Relevant variants of graph attention networks have made progress in tasks related to time series modeling, e.g., traffic flow forecasting [37] and time series forecasting [38] . WebSep 15, 2024 · Based on the graph attention mechanism, we first design a neighborhood feature fusion unit and an extended neighborhood feature fusion block, which effectively increases the receptive field for each point. On this basis, we further design a neural network based on encoder–decoder architecture to obtain the semantic features of point clouds at ...
