openaccess.thecvf.comspatial graph convolution and temporal graph convolution. For spatial graph convolution, the neighbor set of joints is defined as an adjacent matrix A ∈ {0,1}N×N. To spec-ify the spatial location of graph convolution, the adjacent matrix is typically partitioned into 3 partitions: 1) the cen-tripetal group, which contains neighboring nodes ...

arxiv.orgof spatial-temporal graph convolution (ST-GCN) will be applied and gradually generate higher-level feature maps on the graph. It will then be classified by the standard Softmax classifier to the corresponding action category. the form of 2D or 3D coordinates, we construct a spatial temporal graph with the joints as graph nodes and natural

openaccess.thecvf.comspatial-temporal graph, which is a series of disjoint and isomorphic skeleton graphs at different time steps carrying information in both spatial and temporal dimensions. For robust action recognition from skeleton graphs, an ideal algorithm should look beyond the local joint con-nectivity and extract multi-scale structural features and

www.ijcai.org3.2 Graph CNNs for Extracting Spatial Features The trafÞc network generally organizes as a graph structure. It is natural and reasonable to formulate road networks as graphs mathematically. However, previous studies neglect spatial attributes of trafÞc networks: the connectivity and globality of the networks are overlooked, since they are split
