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{...
基于谱方法的图卷积神经网络(Spectral Graph Convolutional Network)也应运而生,一时间大有文体两开...噢不,百花齐放的态势。但诚然新生力量有着席卷一切的朝气,却也不可避免地带有不够完备洗练的稚嫩。 归根到底,还是因为SGFT借以发家的压箱底的本事——傅里叶变换,本身具有一定的局限性。在这方面,信号处理专业出...

Despite the progress that has been made, rich and informative spectral information of HSI has been largely underutilized by existing methods which employ convolutional kernels with limited size of receptive field in the spectral domain. To address this issue, we propose a spectral graph reasoning ...
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
