Making sense of torch_geometric utils softmax
If you've spent any time building Graph Neural Networks (GNNs), you've likely realized that torch_geometric utils softmax is one of those tiny but absolutely essential tools in your PyTorch Geometric (PyG) toolkit. It's the secret sauce behind graph attention mechanisms and edge weight normalization. Unlike a standard softmax you might use in a vanilla neural network, the graph version has to handle something much more chaotic: irregular connectivity. ...
