1. 本文亮点 使用DTW算法计算时间序列相似度,生产不同的子图,然后将多个子图和预先给定的空间领接矩阵集成成为一个时空融合图,得到隐藏的时空依赖关系。 引入门控膨胀卷积算法,并提出一种新的空间图和时间图的融合方法。 2. 现有方法的局限性 大多数现有模型仅利用给定的空间邻接矩阵进行图形建模,在对邻接矩阵建模时...
框架:它由(1)输入层,(2)stacked Spatial-Temporal Fusion Graph Neural Layers and (3) an output layer 输入和输出层是一个和两个全连接层,然后是激活层,如“ReLU”。每个Spatial-Temporal Fusion Graph Neural Layer由多个时空融合图神经模块(STFGN模块)和一个门控CNN模块组成,该模块包含两个并行的一维扩张卷...

2) The susceptibility of the existing graph neural networks (GNNs) to oversmoothing reflects an inherent limitation of these networks. As the network layers deepen, all node representations tend to converge to a uniform value, which greatly affects the ability of the employed model to capture long...

Gated GNN [后补] 最后像ASTGCN一样也是用Huber loss作为损失函数 附加知识点 dynamic time warping的作用是比较序列的相似性,举个例子是同一个人在不同时刻发同一个音,也不一定会有相同的时间序列。这样传统的欧式距离就无法计算。他具体怎么计算:比如简化来看,两段序列m和n,分别对于m和n个特征,逐一计算[m,n...
