reset_parameters()

Resets all learnable parameters of the module.

forward(x: Tensor, adj: Tensor, mask: Optional[Tensor] = None, add_loop: bool = True) → Tensor

Forward pass.

Parameters:

• x (torch.Tensor) – Node feature tensor \(\mathbf{X} \in \mathbb{R}^{B \times N \times F}\), with batch-size \(B\), (maximum) number of nodes \(N\) for each graph, and feature dimension \(F\).

• adj (torch.Tensor) – Adjacency tensor \(\mathbf{A} \in \mathbb{R}^{B \times N \times N}\). The adjacency tensor is broadcastable in the batch dimension, resulting in a shared adjacency matrix for the complete batch.

• mask (torch.Tensor, optional) – Mask matrix \(\mathbf{M} \in {\{ 0, 1 \}}^{B \times N}\) indicating the valid nodes for each graph. (default: None)

• add_loop (bool, optional) – If set to False, the layer will not automatically add self-loops to the adjacency matrices. (default: True)
