Graph WaveNet for Deep Spatial-Temporal Graph Modeling - …

Graph WaveNet for Deep Spatial-Temporal Graph ModelingZonghan Wu1,Shirui Pan2 ,Guodong Long1,Jing Jiang1,Chengqi Zhang11 Centre for Artificial Intelligence, FEIT, University of Technology Sydney, Australia2 Faculty of Information Technology, Monash University, , Graph Modeling is an importanttask to analyze the spatial relations and temporaltrends of components in a system. Existing ap-proaches mostly capture the spatial dependency ona fixed Graph structure, assuming that the under-lying relation between entities is , the explicit Graph structure (relation)does not necessarily reflect the true dependency andgenuine relation may be missing due to the incom-plete connections in the data. Furthermore, ex-isting methods are ineffective to capture the tem-poral trends as the RNNs or CNNs employed inthese methods cannot capture long-range tempo-ral sequences.

proposed a first approximation of Chebyshev spectral fil-ter [Defferrard et al., 2016]. From a spatial-based perspec-tive, it smoothed a node’s signal by aggregating and trans-forming its neighborhood information. The advantages of their method are …
