Check out our paper "Network community detection via neural embeddings" led by @sadamori (w Filippo Radicchi and Santo Fortunato)!
https://www.nature.com/articles/s41467-024-52355-w
We argue that n2v can encode community structure down to the detectability limit due to its connection to spectral embedding.
Approaches based on neural graph embeddings have shown their effectiveness for complex networks analysis, including link prediction and node classification. The authors uncover strengths and limits of neural embeddings with respect to the task of detecting communities in networks.

Come join us at the Inverse Complexity Lab! @invcomplexity
We’re hiring a post-doctoral researcher to join our group at IT:U, Linz, Austria.
https://skewed.de/lab/call.html
Deadline is 30 Nov 2024.
We are looking for an early-stage or more advanced postdoctoral scholar who is interested in building on our ongoing projects, or developing their own research agenda related to inverse problems in network science, complex systems modeling, and/or connections to machine learning.
This position is not bound to a particular research project, and the successful applicant will enjoy intellectual independence and freedom to choose research topics.
We’re seeking applicants with a background in Physics, Computer Science, Statistics, Applied Mathematics, or related fields, and with an interest in interdisciplinary research.
This position is guaranteed for 3 years. The gross salary range is € 66,532 to € 72,000 (indexed for inflation), depending on previous experience.
The employment conditions in Austria include completely free health care (also for family members), social security benefits, 25 days per year of paid vacations, flexible working hours, and possibility of home office.

This paper looks like a nice guide for causal inference with instrumental variables. I haven't read whole thing closely yet, but it seems to go through each assumption and what happens if they are violated (not often exposed & explained well).
