heteSAGE is semi-supervised graphSAGE model that support metapaths of heterogeneous features.
- Heterogeneous features include sparse and dense features of multi type of vertexes.
- Share weights between multi-metapaths
- Use the attention mechanism to aggregate the results of multi-metapaths embedding of the same node type
- Use graphSAGE aggregate method to aggregate multi-hops features
trainning sample contains <target id, context id, ..., label>
