Proposed merge of Draft:Graph neural network into Graph neural network

Draft contains more information than article. Robert McClenon (talk) 05:34, 7 July 2021 (UTC)[reply]

Oh wow, yeah your article is far more detailed. I second this Zaya (talk) 16:17, 7 July 2021 (UTC)[reply]

The tone of the draft is practitioner oriented, as seen here:

On the other hand, GNN not only be able to applied to non-Euclidean data but also Euclidean data such as sentences, images or videos since such data can be represented as graph data if organized properly.

That's effectively speculative language lifted right out of a funding request (more research required).

On the other hand, the following encyclopedic claim from the current stub article is not found in the draft:

It has been mathematically proven that GNNs are a weak form of the Weisfeiler–Lehman graph isomorphism test, so any GNN model is at most as powerful as this test.

On the basis of these surface details, I'm concerned that the draft is so thoroughly practitioner oriented as to be somewhat unbalanced. It's not the point of Wikipedia to document GNNs as a happening thing. On the other hand, I applaud the tremendous expansion of coverage the draft seems to embody (I'm not expert enough to decide this for myself).

The current stub is woefully inadequate, so in my mind the question is not whether to merge, but how to merge. First of all, the matter is to decide the right encyclopedic stance, and then I think the best of both worlds will easily fall into place. — MaxEnt 21:51, 24 July 2021 (UTC)[reply]

I am new to editing a wiki article and my profession is actually researching about deep learning in computer vision, so indeed my writing style was more like a computer-vision-oriented review paper, and I am not sure if this is proper for a wiki article.

The ICLR paper related to this sentence:

It has been mathematically proven that GNNs are a weak form of the Weisfeiler–Lehman graph isomorphism test, so any GNN model is at least as powerful as this test.

can be placed after GAT in the draft as another subgraph since the model proposed in the paper (GIN) is also a spatial approach. And the rest of the current article can be easily added to the introduction of the draft. Since I only write things that I have surveyed during my research, most methods I mentioned are computer-vision-oriented and hence somehow unbalanced. In my opinion, my draft is just a start, and it surely requires more experts in different areas who are using GNNs such as social networks, citation networks, biological or chemistry science fields to help edit this artical.

Overview of the article

A very detailed article, with a good math formalism to explain how to represent and implement GNNs. You may contact me at my talk page.

Review of the article

SlipherD (talk) 12:58, 1 July 2022 (UTC) -- The article is very well done and explains GNNs in deep detail, covering also some interesting applcations. My edits regarded only the use of the word "where" after a formula, which should - in general - not be capitalized. Also, but I would like confirmation on this, perhaps the $a$ just before the end of the subsection Graph attention network should be an $\mathbf {a}$ ? Good work and thank you![reply]
