Constrained Graph Variational Autoencoders for Molecule Design

NeurIPS 2018poster

Graphs are ubiquitous data structures for representing interactions between entities. With an emphasis on applications in chemistry, we explore the task of learning to generate graphs that conform to a distribution observed in training data. We propose a variational autoencoder model in which both e…

Graph Partition Neural Networks for Semi-Supervised Classification

ICLR 2018workshop

We present graph partition neural networks (GPNN), an extension of graph neural networks (GNNs) able to handle extremely large graphs. GPNNs alternate between locally propagating information between nodes in small subgraphs and globally propagating information between the subgraphs. To efficiently p…
