How to predict links between present and a new node with PyG/GraphSage autoencoder?

I am a newbee in the field of GNN and want to use PyTorch Geometric (PyG) to train a Graph Neural Network (GNN) to predict links (edges) between nodes in a graph using an autoencoder (with a modified version of the PyG link prediction example with…

Keras model predicting different outputs for the same input

I am using stellargraph for learning a GraphSage model. This is my code: num_samples = [10, 5] unsupervised_samples = UnsupervisedSampler(G,nodes=G.nodes(),length=10, number_of_walks=5) # Generate training data for the encoder model generator =…

Neo4j GraphSage: inconsistency between runs

On Neo4j, running gds.beta.graphSage.mutate yields inconsistent results: for the same model, a given node n gets different embeddings between runs. This happens despite the graph being constant (nodes, arcs, initial features, they are all the same…
