WebOct 24, 2024 · Unsupervised GraphSAGE has now been updated and tested for reproducibility. Ensuring all seeds are set, running the same pipeline should give reproducible embeddings. Currently "ensuring all seeds are set" for unsupervised GraphSAGE means: fixing the seed for these external packages: numpy, tensorflow, … Webh_neigh = graph. dstdata [ 'neigh'] # GraphSAGE GCN does not require fc_self. rst = self. fc_self ( h_self) + self. fc_neigh ( h_neigh) # activation if self. activation is not None: rst = self. activation ( rst) # normalization if self. norm is not None: rst = self. norm ( rst) return rst class GraphSAGE ( nn.
