Gated Graph Sequence Neural Networks. Recent advances in graph neural nets (not covered in detail here) Attention-based neighborhood aggregation: Graph Attention Networks (Velickovic et al., 2018) Graph-structured data appears frequently in domains including chemistry, natural language semantics, social networks, and knowledge bases. A graph-level predictor can also be obtained using a soft attention architecture, where per-node outputs are used as scores into a softmax in order to pool the representations across the graph, and feed this graph-level representation to a neural network. We have explored the idea in depth. We provide four versions of Graph Neural Networks: Gated Graph Neural Networks (one implementation using denseadjacency matrices and a sparse variant), Asynchronous Gated Graph Neural Networks, and Graph ConvolutionalNetworks (sparse).The dense version is faster for small or dense graphs, including the molecules dataset (though the difference issmall for it).
