Graphsage torch
WebWhat is PyG? PyG is a library built upon PyTorch to easily write and train Graph Neural Networks for a wide range of applications related to structured data. PyG is both friendly to machine learning researchers and first-time users of machine learning toolkits.

The difference between edge_weight and edge_attr is that edge_weight is the non-binary representation of the edge connecting two nodes, without edge_weight the edge connecting two nodes either exists or it doesn't (0 or 1) but with the weight the edge connecting the nodes can have arbitrary value. Whereas edge_attr means the features …

We also provide a shell script run.sh for other datasets. WebThis tutorial formulates the link prediction problem as a binary classification problem as follows: Treat the edges in the graph as positive examples. Sample a number of non-existent edges (i.e. node pairs with no edges between them) as negative examples. Divide the positive examples and negative examples into a training set and a test set.
