Machine learning on graphs: A free, four part lecture course (octavian.ai)

It's possible others want to see a discussion on this topic but are themselves not familiar with it, and are therefore voting it up to draw attention to it. But I am speculating.

Could also be that there is little to discuss since they are planning to launch the course only in June.

Folks might just have found it interesting enough, registered for the course, upvoted it.

There are links to some interesting (basic) content on ML on graph data though

In the preamble they mention [0]. So I assume it is about when your data set consists of graphs (ML on graphs).
