Graph neural network (Graph NN) is a recent research hotspot, especially the "Graph Networks" proposed by DeepMind, which is expected to enable deep learning to achieve causal reasoning. However, this paper is difficult to understand. Dr. Deng Wei, the chief AI scientist of Fosun Group and the founder of DaDian Medical, analyzed the significance of DeepMind “Figure Network” based on the clear classification of GNN review by Professor Yu Shilun of Tsinghua University.
