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{...

Furthermore, the feature fusion for the entropy feature vectors and the original data is realized by the multi-scale convolutional layers. Then, the spectral graph convolution network (SGCN) is employed to detect the abnormal electricity consumption and to output specific electricity consumption case....
首先,由于在一般图上没有类似FFT的算法,所以正变换和反图的傅里叶变换的计算产生了复杂度为O(n^2),其次,光谱滤波系数是基相关的,因此,在一个图上学习到的光谱CNN模型不能转移到另一个图上。这与[37]相反,其中滤波器系数的频率响应表示为\hat{g_i}=g(\lambda_i),其中g(\lambda)是频率λ的平滑传递函数...

CNNs reduce the size of the grid via pooling and subsampling layers. 多尺度聚类( multiscale clustering):they input all the feature maps over a cluster, and output a single feature for that cluster. Figure 1 illustrates a multiresolution clustering of a graph with the corresponding neighborhoods...
In particular, we propose two constructions, one based upon a hierarchical clustering of the domain, and another based on the spectrum of the graph Laplacian. We show through experiments that for low-dimensional graphs it is possible to learn convolutional layers with a number of parameters ...
In recent years, graph convolutional network has been widely used in hyperspectral image classification because of its feature aggregation mechanism, which can simultaneously represent the features of a single node and neighboring nodes. However, there a
