How Knowledge Graphs Will Transform Data Management And Business

Nice article that describes how different companies including BenevolentAI are using knowledge graphs and what are the challenges of using them.

Generalization Bounds of GNN

Expressiveness, that is what class of graphs can be represented by GNN, has been extensively studied during the last two years. On the other hand, generalization, i.e. ability to represent correctly unseen graphs is just gaining attention. Here are some papers that study generalization of GNN.

Tsinghua University Releases First AutoML Toolkit for Graph Datasets & Tasks

At least in the research papers, hyperparameter tuning, feature engineering, architecture and model search, stacking and boosting have been largely ignored and I have a good faith that in the coming year there will be more papers that extensively perform all of those to gain additional boost in performance. This AutoGL PyTorch Framework does just this. It's based off PyG, contains a few standard datasets and models, has several HP algorithms, generates graphlet, pagerank, and other features, stacks models' predictions, and more. Looks very promising.

Graph Machine Learning: Highlights 2020

Here is my short presentation at ODS (video in Russian) about the state of Graph ML in 2020: top-3 applications and perspectives for the next year.

Geometric ML becomes real in fundamental sciences

A new post by Michael Bronstein: top-3 papers in 2020 about applications of graphML to drug development. I agree that this field is getting momentum and more companies, small and big, will look into application of GNNs to molecule predictions. There is even a graph ML researcher position available in the industrial company. Exciting times for those who are interested in graphs, ML, and biology.

Happy New Year 2021!

Thank you all who followed and shared my posts this year! My very first post was a year ago and since then I wrote 380+ more. The community grew to 1700+ subscribers, who motivated me to learn more and share exciting works done in this community. In 2021 I wish you stay connected in this disconnected world! Peace.
