PyG (PyTorch Geometric) is a library built upon PyTorch to easily write and ... thanks to its easy-to-use message passing API, and a variety of operators ...

Creating Message Passing Networks¶. Generalizing the convolution operator to irregular domains is typically expressed as a neighborhood aggregation or message passing scheme. With \(\mathbf{x}^{(k-1)}_i \in \mathbb{R}^F\) denoting node features of node \(i\) in layer \((k-1)\) and \(\mathbf{e}_{j,i} \in \mathbb{R}^D\) denoting (optional) edge features from node \(j\) to node …

Oct 24, 2021 · 2 Classes you need to self define when you implement Graph Neural Network(GNN): MyNet(pytorch.nn.Moduel) MyGraphModel(torch_geometric.nn.MessagePassing) MyNet(pytorch.nn.Moduel) In your overall model structure, you should implement: (in __init__): call a MessagePassing child class to build massage-passing model (in forward): make sure the data follows the requirement of MessagePassing child class do the “iterative massage passing"(K-times) in forward, the final output will be the node ...

Library Highlights

r"""Computes or updates features for each edge in the graph. This function can take any argument as input which was initially passed. to :meth:`edge_updater`. Furthermore, tensors passed to :meth:`edge_updater` can be mapped to.

PyG provides the MessagePassing base class, which helps in creating such kinds of message passing graph neural networks by automatically taking care of message propagation. The user only has to define the functions ϕ , i.e. message (), and γ , i.e. update (), as well as the aggregation scheme to use, i.e. aggr="add", aggr="mean" or aggr="max".
