三、Graph Convolutional Network (GCN) 对于图结构数据,GCN可以对直接连接的节点进行卷积运算,对本地信息进行编码。通过多层GCNs的消息传递,图中的每个节点都可以了解到更多的全局信息。大多数以前的工作(Zhang et al.,2019;Sun等人,2019b)通过编码依赖树和合并单词之间的依赖路径来扩展GCN模型。他们在句子的句法依赖...
code:ccchenhao997/dualgcn-absa 3 Graph Convolutional Network (GCN) 受传统卷积神经网络(CNN) 和图嵌入的启发,GCN 是一种直接在图上运行的高效 CNN 变体(Kipf 和 Welling,2017)。对于图结构化数据,GCN 可以在直接连接的节点上应用卷积操作来编码局部信息。通过多层 GCN 的消息传递,图中的每个节点都可以学习到...
Furthermore, a dense graph convolutional network is designed to extract and fuse the spatial鈥搒pectral and topological features from the shallow to deep layers for classification. A soft-shifting optimization strategy is implemented by defining a new loss from full bands and selected bands to ...

non-local就是gcn中的特例,文中只是downsample之后再进行non-local,而且效果更好。但是channel维度上并不是先进行降维。channel(也就是文章中说的feature space)加了一个laplacian smoothing(Wf作为训练的权重),似乎没有关于这个laplacian smoothing的 ablation。
Our Dual Graph Convolutional Network (DGCNet) models the global context of the input feature by modelling two orthogonal graphs in a single framework. The first component models spatial relationships between pixels in the image, whilst the second models interdependencies along the channel dimensions of...
Graph Convolutional Network (GCN) 这个就很传统了,大家再熟悉下。 DualGCN Syntax-based GCN (SynGCN) 为了解决依存句法产生定的错误问题,这里使用的是生成依存句法之前的依存关系概率矩阵,其中,这里使用的目前句法SOTA模型LAL-Parser (Mrini et al., 2019). ...
