ChebyNet的卷积公式为: 令K=1,即只使用一阶切比雪夫多项式。 此时, 由切比雪夫多项式的迭代定义我们知道.所以 令 ,则 上式 又 是对称归一化的拉普拉斯矩阵,即 因此上式 再令 如果我们令 则 将其推广到矩阵形式则得到我们耳熟能详的GCN卷积公式: 未完待续。

ChebyNet[Defferrardet al., 2016] introduces a polynomial parametrization to convo-lution kernel, i.e., convolution kernel is taken as a polyno-mial function of the diagonal matrix of eigenvalues. Subse-quently, Kipf and Welling[Kipf and Welling, 2017] proposed graph convolutional network (GCN) via a localized rst-order approximation to ChebyNet.
