dgl.ops.copy_e_minο
- dgl.ops.copy_e_min(g, x)ο
Generalized SpMM function. It regards edge feature as message. Then aggregates the message by min on destination nodes.
- Parameters:
g (DGLGraph) β The input graph
x (tensor) β The edge features.
- Returns:
The result tensor.
- Return type:
tensor
Notes
This function supports autograd (computing input gradients given the output gradient).
The min function will return zero for nodes with no incoming messages. This is implemented by replacing all infinity values to zero.
