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{...
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...
In this paper, we introduce the novel concept of Graph Convolutional Networks (GCN) for brain analysis in populations, combining imaging and non-imaging data. We represent populations as a sparse graph where its vertices are associated with image-based feature vectors and the edges encode ...

Moreover, by decoding the holistic FCN from various perspectives through multiple spectral Graph Convolutional Neural Networks and fusing their results with decision-level ensembles, we further improve the performance of MDD diagnosis. Our approach is easily implemented with minimal modifications to ...
