Node Clustering: 根据连接性将相似的节点分组。 Link Prediction: 预测缺失的链接。 Influence Maximization: 识别有影响的节点。 Extending Convolutions to Graphs 卷积神经网络在图像中提取特征方面是非常强大的。而图像本身可以看作是一种非常规则的网格状结构的图,其中单个像素为节点,每个像素处的RGB通道值为节点特征...

Graph embedding(GE)也叫做network embedding(NE)也叫做Graph representation learning(GRL),或者network representation learning(NRL),最近有篇文章把graph和network区分开来了,说graph一般表示抽象的图比如知识图谱,network表示实体构成的图例如社交网络, 我觉得有点过分区分了。图1.1是整个GE大家族,本文只介绍绿色的,蓝色...
社交广告(lookalike)/社区挖掘/link prediction CV领域,尤其是3D 例如:基于人体骨架关键点的人类动作识别——ST-GCN(AAAI 2018)。 ST-GCN主要原理: 1. 在每一帧内部,按照人体的自然骨架连接关系构造空间图; 2. 在相邻两帧的相同关键点连接起来,构成时序边; 3. 所有输入帧中关键点构成节点集(node set),步骤 ...
