[32] first apply GCNs to model the skeleton data. They construct a spatial graph based on the natural connections of joints in the hu-man body and add the temporal edges between correspond-

In graph-based SLAM, the poses of the robot are modeled by nodes in a graph and labeled with their position in the environment [21], [18]. Spatial constraints between poses that

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

On the other hand, we have non-spectral approaches (Duvenaud et al., 2015; Atwood & Towsley, 2016; Hamilton et al., 2017), which define convolutions directly on the graph, operating on groups of spatially close ...
