I really enjoyed this paper on graphical attention RNNs. It is basically a clever way to combine a Graph Attention Mechanism (Veličković et al., 2017) with a Diffusion Convolutional RNN (Li et al., 2017). As the authors did not provide an implementation, I decided to create one myself. My implementation can be found here.

Hope it may be of use to somebody. Any feedback would be greatly appreciated.
