Graph Neural Networks in Keras

[Patrick Reiser]

Hello,

I am working with Graph Neural Networks in science and research.

Graph neural networks have gained a lot of attention in recent years. 

I have started to work with batched graphs in the style of keras by creating kgcnn (https://github.com/aimat-lab/gcnn_keras) some time ago.

Of course this was my first attempt in preparing general modules in a library style and there is much I would improve on in a second iteration, especially on the backend and data loading part.

I would like to ask the keras developers, if there is a Keras-Graph or Keras-GNN similar to Keras-CV or Keras-NLP planned in the future?

An implementation within Keras-Core sounds very intriguing. 

If yes then I am happy to contribute.

Thanks

Hi Patrick,

Nice work with KGCNN!

There's TF-GNN, which might as well be called Keras-GNN since it's entirely based on the Keras API.

TF-GNN is likely going to be TF-only for the foreseeable future, due to its fundamental reliance on `tf.ExtensionTypes` for custom graph types. If you want to start something that works with JAX and PyTorch as well, there's definitely an opportunity there.

Best,

Francois

Hello,

thank you very much for your fast answer.

Okay I understand, I think I would like to start something that works with JAX and PyTorch as well.

Thanks
Patrick
