Center node: "graph convolutional networks for molecules"
  Abstract: Representation learning for molecules is important for molecular properties prediction, material design, drug screening, etc. In this work a graph convolutional network architecture for learning representations for molecules is presented. An operation for convolving k-neighbourhood of a specific node in graph is defined, which is corresponding to kernel size of k in convolutional neural networks. Besides, A module of adaptive filtering is defined to find the sampling locations based on graph connections and node features.

Connected through hyperedge HE-1 (induced by source paper "graphsaint graph sampling based inductive learning method"):
