Semi supervised classification with graph convolutional networks

  1. 1. SEMI-SUPERVISED CLASSIFICATION WITH GRAPH CONVOLUTIONAL NETWORKS
  2. 2. Schematic depiction of multi-layer Graph Convolutional Network (GCN) for semisupervised learning with C input channels and F feature maps in the output layer. The graph structure (edges shown as black lines) is shared over layers, labels are denoted by Y
  3. 3. A neural network model for graph-structured data should take both the graph structure and feature description of nodes into account Fast Approximate Convolution on Graphs:
  4. 4. D D-AA Symmetric normalized Laplacian: Combinatorial Laplacian: Graph structure
  5. 5. Loss function:
  6. 6. experiments
  7. 7. Appendix: Proof: 1.
  8. 8. 2.
  9. 9. 3.
