To address these challenges in emotion recognition, we propose a novel neural network model named Temporal-Spectral Graph Convolutional Network (TSGCN). To capture high-level information distributed in time, spatial, and frequency domains, TSGCN considers both neural oscillation changes in different ...

The construction of the network model has become the main technology of hyperspectral image classification, and it is also the current research focus of hyperspectral classification. In terms of graph convolutional networks, Mou et al.19proposed a nonlocal graph convolutional network (GCN). Wan et ...
算法名称:GCN(Graph Convolutional Network),2017 ICLR 直接处理图数据的卷积神经网络先后经历了:Spectral GCN、Chebyshev GCN、GCN的演变,其内在动力是通过不断简化模型、提升计算效率。GCN可以看作Spectral GCN的一阶近似表达,它更是连接谱域与空域图卷积网络的桥梁。
而如果你看过谱聚类(详细可看图卷积神经网络(Graph Convolutional Network, GCN)),当M等于标准化的laplace矩阵L时,即 \displaystyle L=I-\frac{1}{d} A ,你会知道如果设 \displaystyle x\in \{0,1\}^{V},(用1表示A类结点,用0表示B类结点),那么这A,B两类结点把他切割开,于是 \displaystyle \mathbf{...
Graph Convolutional Networks (GCNs) have drawn significant attention and become promising methods for learning graph representations. The most GCNs suffer the performance loss when the depth of the model increases. Similarly to CNNs, without specially designed architectures, the performance of a network...
