Inverse Complexity Lab

Last week we had our second “Inverse Complexity Lab Retreat” at wonderful Traunkirchen! skewed.de/lab/group.ht... Nothing like eldritch C++ incantations by the sunny lakeside! 🏖️

Good news everyone! 🎉 The new version 3.0 of graph-tool is just out with major improvements! See below. graph-tool.skewed.de graph-tool is a comprehensive and efficient Python library to work with networks, including structural, dynamical, and statistical algorithms, as well as visualization. 1/N

Early Christmas... The @frame.work laptops for our group members @invcomplexity.skewed.de arrived last week!

I’m happy to share that, as of April 1st, I will be taking on a W3 Professorship in Complex Systems and Network Science at the Goethe University Frankfurt @goetheuni.bsky.social.

Want to learn more about our recent work disentangling the conflation between hypergraphs and higher-order interactions? I will be giving a @beyondtheedge.network seminar March 16, 2026 3:00 PM CET. Paper: arxiv.org/abs/2602.16937 Zoom link here: www.beyondtheedge.network/event/semina...

New blog post: "Higher orders need higher standards" skewed.de/lab/posts/hi... I discuss our current work disentangling misconceptions around "higher-order" networks: arxiv.org/abs/2602.16937 Explainer thread for the paper here: bsky.app/profile/tiag...

New on the arxiv: “Graphs are maximally expressive for higher-order interactions” arxiv.org/abs/2602.16937 We clarify central misconceptions in the recent literature on "higher-order networks". w/ @piratepeel.bsky.social , @manlius.bsky.social, and @thilogross.bsky.social Explainer 🧵: 1/N

I wrote a blog post about the often stated but never explained assumption that communities in graphs should always be connected. This is inconsistent with statistical significance and null models that underlie the most widely employed methods. skewed.de/lab/posts/co...

Just out on @royalsocietypublishing.org: "Scalable network reconstruction in subquadratic time" royalsocietypublishing.org/doi/10.1098/... Previous explainer thread here: bsky.app/profile/tiag... Code here: graph-tool.skewed.de/static/docs/...

Double feature, just out on @royalsocietypublishing.org: "Uncertainty quantification and posterior sampling for network reconstruction" Previous explainer thread here: bsky.app/profile/tiag... Code here: graph-tool.skewed.de/static/docs/... royalsocietypublishing.org/doi/10.1098/...

Very happy that Lena joined the group! 🚀

🎓 Short interview with me by the lovely people at @cams.ehess.fr , where I wrapped up my PhD this summer ✨ In 🇫🇷, with a longer version also available in 🇬🇧: shorturl.at/FjNRA

Tomorrow 1.30-2.30pm, poster ID 82

Attending @ic2s2.bsky.social? Checkout the poster presented by @thomrobiglio.bsky.social! #ic2s2

New preprint: “Multiscale patterns of migration flows in Austria: regionalization, administrative barriers, and urban-rural divides”, with @thomrobiglio.bsky.social, Martina Contisciani, @martonkarsai.bsky.social, arxiv.org/abs/2507.11503

Are you from the US and would like to work as a postdoc in Austria, maybe in our lab? 25 new fellowships will be available in July from the @oeaw.bsky.social: www.oeaw.ac.at/en/news/25-n... If you are interested; get in touch!

@invcomplexity.skewed.de bike train to @netsciconf.bsky.social @ituaustria.bsky.social

A couple of weeks ago we had our first “Complexity Lab Retreat” at great location in Traunkirchen! skewed.de/lab/group.ht... We had the opportunity to flex our methodological muscles and learn the dark secrets of the C++ internals of @graph-tool.skewed.de! 💀🤘

🚨 New paper on ArXiv: “Uncertainty quantification and posterior sampling for network reconstruction” TL;DR; We present an efficient method to sample the entire ensemble of possible network reconstructions that are compatible with an indirect observation, e.g. a dynamics. Short thread: 1/N

Good news for Arch GNU/Linux users! Graph-tool is now available in the main repository! To install it, just do: pacman -S python-graph-tool The days of compiling graph-tool from AUR are over! Rejoice! 🎉

Get 2025 started by reducing your compile times! graph-tool.skewed.de

🚨 Job alert 🚨 IT:U is hiring 5 professors (open rank) in Data Science, very broadly defined! Focuses include (among others): 1. Theoretical Foundations of Data Science 2. Data Science in Biological Systems 3. Data Science in Human Mobility it-u.at/en/careers/p... 1/2
