-----------------------------------------------------

*PyTorch Geometric Signed Directed* is a signed and directed extension library for [PyTorch Geometric](https://github.com/pyg-team/pytorch_geometric). It follows the package structure in [PyTorch Geometric Temporal](https://github.com/benedekrozemberczki/pytorch_geometric_temporal).

The library consists of various signed and directed geometric deep learning, embedding, and clustering methods from a variety of published research papers and selected preprints. 

We also provide detailed examples in the [examples](https://github.com/SherylHYX/pytorch_geometric_signed_directed/tree/main/examples) folder.
