Is it possible to apply your GCN on directed graphs ?

Hi @tkipf ,

I'm wondering if it's possible to apply GCN on directed graphs !

If no, is that related to the fact that :

1. Laplacian is not invariant to rotation. how come ?
2. Laplacian matrix is not circulant ? If yes, why it is important to be circulant ?

Thank you a lot Thomas
