May 07, 2021 · GAE and Node2Vec for edge analysis. Today's tutorial shows how to use previous models for edge analysis. We first use Graph Autoencoder to predict the existence of an edge between nodes, showing how simply changing the loss function of GAE, can be used for link prediction. Later, we propose the use of Node2Vec for edge-label prediction.

Aug 10, 2021 · The code used in this example was taken from the PyTorch Geometric’s GitHub repository with some modifications . A Summary. To summarize everything we have done so far: Generate numerical representations for each node in the graph (node degree in this case). Construct a PyG custom dataset and split data into train and test.
