Multi-View Graph Convolutional Network(MV-GCN) 多视图学习是以一种基础的数据增强技术可以从不同角度描述数据。图建模的是关系,而这种关系是多样的,单一的视图很难精确描述,并且,网络中可能会有噪声。为丰富结点之间的关系,本文从高阶拓扑和特征相似性两个视角出发。基于原始邻接矩阵和原始特征生成两个视图并使用任...
具体来说,我们引入了一个传播卷积块( Propagating Graph Convolution),并重用了时间模块用来从空间和时间域近似估计缺失的停车位,然后通过基于熵的机制将它们融合。 用北京和深圳两个城市的数据来评估SHARE(Semi-supervised Hierarchical Recurrent Graph Neural Network),结果显示比其余七个要好。 3. Framework Overview ...
Graph neural networkHypergraphSoft SSLGraph-based semi-supervised learning (SSL) assigns labels to initially unlabelled vertices in a graph. Graph neural networks (GNNs), esp. graph convolutional networks (GCNs), are at the core of the current-state-of-the art models for graph-based SSL ...

你的graph建的这么漂亮的话(上面都是蓝色的,下面都是红色的). 你的data要足够多,如果data不够多的话,这个地方没收集到data,那这个点就断掉了,那这个information就传不过去了,比如下图就出现四个小的cluster。 其实你要算smothness时不一定要放在output的地方,如果你今天是deep neural network的话,你可以把你...
To circumvent these problems, a novel semi-supervised locality-preserving dense graph neural network (GNN) with autoregressive moving average (ARMA) filters and context-aware learning (DARMA-CAL) is proposed for HSI classification. In this work, we introduce the ARMA filter instead of a spectral ...
