Projects

XGCN
XGCN is a light-weight and easy-to-use library for large-scale GNN embedding. XGCN includes xGCN - an implementation for the TheWebConf 2023 paper: xGCN: An Extreme Graph Convolutional Network for Large-scale Social Link Prediction - which achieves remarkable accuracy and efficiency on large graphs, including an industrial dataset with 100 million nodes.
