Machine learning isn’t for everyone. I know chatgpt seems simple but it’s not. Don’t enter a field that you don’t have a passion for just because of it.

Thanks for the concern. Not entering the field because of ChatGPT. I have been in the field before the all the hype. I had simply moved to MLoPs and edge AI side of things in order to explore new items

I am working in this field for my PhD, so I think I can help.

A bit of self promotion, but my Master's thesis was about GNNs: https://arxiv.org/abs/2211.03666. It should be very beginner-friendly, since I had to write it while also learning about this step by step.

"Introduction to. Graph Neural Networks". Zhiyuan Liu and Jie Zhou. Tsinghua University is slightly outdated due to how fast this field is going on, but good intro.

"Graph Neural Networks Foundations, Frontiers, and Applications" (https://graph-neural-networks.github.io/) is cutting-edge, good reviews. I haven't read it though, but looks very promising.

Overviews and articles are also great, e.g. https://distill.pub/2021/gnn-intro/ or a well known (in this field) https://arxiv.org/abs/1901.00596. You should also definitely read papers about GCN (very intuitively written), GAT, GraphSAGE and GIN, the most classic 4 graph convolution architectures.

Fair comparison is, unfortunately, not common in this field. Many well-known works, e.g. GIN, do not even use a test set, and are quite unclear about this, so approach every paper with a lot of suspicion. This paper about fair comparison is becoming more and more used: https://arxiv.org/abs/1912.09893. This baseline, not GNN but similar, gives very strong results: https://arxiv.org/abs/1811.03508. I will be releasing a paper about a related method, LTP (Local Topological Profile), you can look out for it in the later part of the year.

Other interesting architectures to read about: graph transformers, Simple Graph Convolution (SGC), DiffPool, gPool, PinSAGE, DimeNet.

This very exciting area is just starting to develop, despite a lot of work done. There is no well working way to do transfer learning, for example. It is very hard to predict what will happen in 4-5 years, but e.g. Google Maps travel time prediction is currently based on GAT, and Pinterest recommendations on PinSAGE, so graph-based ML is already used in large-scale production systems. Those methods are also more and more commonly used in biological sciences, where molecular data is ubiquitous.

Thanks for all the resources!!

IMO the order of papers should be, although i realise this may be a bit too much looking back

• start off with spectral graph papers and the label propogation papers such as zhu 2003 zhou 2004.
• then the spectral convolution papers such as defferrard 2016.
• then the gcn paper and maybe the gat paper and how powerful are graph nns.

From there you are well set up to pick your poison on which type of graph ml to focus on. Dynamic vs static, hetro vs homo etc.

Some cool people to follow (i dont know much about the social media stuff)

Bronstein at twitter, petar velickovic at deep mind, xavier bresson, william hamilton. Sure there are loads more

Pytorch geometric and dgl have loads of good docs for practical examples.

Stanford CS224W: Machine Learning with Graphs is the best intro imho. You can find course official page in Standford’s website

Thanks!!

Thanks!!
