Missing args in kernel.fit_transform()

1

**Describe the bug** The args in kernel.fit_transform is missing `y`. https://github.com/ysig/GraKeL/blob/33ffff18d99c13f8afc0438a5691cb1206b119fb/grakel/kernels/kernel.py#L169 This will cause problems when send into pipeline, for some kernel methods do not have local fit_transform implantation. **To...

In the implementation of `global_normalize_bipartite_adjacency` function, there is a comment https://github.com/riannevdberg/gc-mc/blob/722f37dde381f9a2c2aa1f91e1e79a63dfba5c03/gcmc/preprocessing.py#L79 But I don't see the augmented adj (adj+I) in and before the function. Where is the adj+I? Why does...

Hi @Ruiqi-Hu, I see here https://github.com/Ruiqi-Hu/ARGA/blob/a970fa583d8c474b18f950da06bf91da03a647db/ARGA/arga/model.py#L67 you injected a Gaussian noise to the first layer. * What's the purpose of doing so? Based on the original implementation of GAE, https://github.com/tkipf/gae/blob/a1aecb00de894859f509f2d392135086a86946a0/gae/model.py#L55-L69...

Compatible with py3

Fix the issue in #186 Changes * send `edge_index` to `device` * assign `self_mat` to `device` to match `edge_index` * passed the `pytest` ```bash $ pytest test/ ============================================ test session...

Overall, if we have two sparse matrices, then the multiplication should be sparse as well, in order to improve the performance. Example like https://github.com/scipy/scipy/blob/a03f15fe43cb68c132192af22deb73b69ef201bf/scipy/sparse/compressed.py#L496-L530 And the `spspmm` function in the...
