SFI's Laurent Hébert-Dufresne has received the 2026 Erdős-Rényi Prize, the top honor for early-career researchers in network science. “This recognition reflects the deeply collaborative nature of complex systems research,” says Hébert-Dufresne.

#CCS2026 @ConfCompSys daily post: 29. TODAY is the abstract deadline for CCS 2026!! ccs26.cssociety.org Complex systems approaches are increasingly in demand in this rapidly changing, challenging world. Join us! cssociety.org sites.google.com/binghamton.e...

These days I saw a lot of arxiv papers (cs.AI and cs.MA) with AI generated schematics, screenshots of web page of plots (eg scatter plot), with captions embedded, too small font, and abuse of colors. I’m full 🫠

Don't miss the chance to assist online! We'd be happy to count with your participation and contributions to the conference, regardless whether they're online or in-person!

Don't forget the submission deadline for CCS on May 15th. October in upstate New York and Binghamton is spectacular and so is the list of keynotes we have planned! #ComplexSystems

This week I presented at this year's @complenet.bsky.social in Zaragoza. It was an amazing conference, with arguably the best cocktails and coffee breaks! 🧇🥐

Congratulation!! Well deserved!

#CCS2026 @ConfCompSys daily post: 22. Complex systems science is a truly interdisciplinary field. Explore the interactive topic network and see how your research fits: bingdev.binghamton.edu/sayama/compl... Abstract deadline May 15th ccs26.cssociety.org

Veronica discussed the integration, collaborations and thematic exploration in european countries using networks and embeddings. Collaborate more over time but money & project stays with the core, and research keeps digging the same rather than exploring new @verorsanigo.bsky.social #complenet2026

Ciro Cattuto gave a keynote speech on data collection, virus spreading (shared classroom matters more than who you are next to), and social dynamics (w/ a kitchen story between Italian and French). #complenet2026

Sebastian Kusch discussed how we can disentangle communities and ranking and proposed SBM models with ranking parameters, closing with a take way “poem” #complenet2026

It was great pleasure to get invitation for keynote speech to this welcoming, intimate conference.

Another great talk from @skojaku.bsky.social. Best talk from last year and keynote this year! The best talk this year will be invited as keynote next year! #CompleNet26

Bernardo introduced a random hypergraph model preserving the label assortativity (and degree) by representing a hypergraph as a bipartite net and swapping edges with the same node label and size of hyper edge. Applied to data to study social consensus (eg US legislation) #networks #complenet2026

How are protein interaction networks generated? We don’t have its evolution history. But can we infer it from the current state (networks and DNAs?) Bukyoung Jhun introduced a Bayesian inference method centered on duplication of genes. #complenet2026

Einstein gave a talk in this room, it turns out.

Bibandhan discusses the impact of airborne diseases on traffic networks! #complenet2026 b co

Breaking symmetries (putting observers in structurally isomorphic nodes) help identify the source of infection. And the number of observers reduces by collecting data about the evolution of disease spreading. #complenet2026

Gorka identified a need for coordinated international effort protecting sea animals that move without passport beyond national border, with a beautiful map of ecological networks. @complenet.bsky.social #complenet2026

CompleNet just started in a beautiful room in Paranonfo in Zaragoza! The photo is the coauthor network of all participants @complenet.bsky.social

The Higgs mechanism was proposed in 1964 by three independent teams. But here is the puzzle🤔: the "disruption index" says Higgs's paper is among the least disruptive ever. So what is going on? In our new paper, just out in #ScienceAdvances, we take up this puzzle: doi.org/10.1126/scia... 👇 1/7

Our paper "Scale invariance and statistical significance in complex weighted networks" is out on PRE: If the distribution of edge weights in your null model depends on the weights' unit, you will be in trouble! @filipisilva.bsky.social @skojaku.bsky.social journals.aps.org/pre/abstract...

I created a tool, snaketail, a snakemake wrapper that fixes workflow and restarts itself automatically when failed. The idea—feeding the tail (error log) to the head (system input) to self-heal—has practical values to create robust automation system! skojaku.github.io/snaketail.html

This is a beautiful visualization of recurrence relations and eigenvectors. (It’s Japanese so plz turn on auto translation).

I've also seen more and more figures that are apparently generated by generative AIs on preprints, with typos, broken arrows, and inconsistency with the main text body. Found yet another one today 🙃.

ppl should stop using ai-generated diagrams. you know i’m not anti-ai but they’re just not good at this yet! the problem is that diagrams have a very specific purpose: they’re meant to compress understanding into few key bits. ai vomits out poor approximations that aren’t conceptually compressed

Come and join our Discrete Laplacian workshop in Dresden, Germany 🙌! With Karel Devriendt, Otto Sumray, and Giulio Zucal, we are organising the workshop in MPI-CBG, 22-25 Jun 2026. Thanks to the support from Heather Harrington's group at CSBD, MPI! Abstract ddl: 1 Mar 2026 More details follow 🧵

New (competition funded) PhD opportunity with me, @iaciac.bsky.social and @dralgernon.bsky.social www.findaphd.com/phds/project... Higher-order networks and animal communication. Suited to someone keen on network science theory/computational modeling and keen to adapt this to ecology & evolution.

Can AI be a good task manager? I tested myself as a weekend project - skojaku.github.io/invisible-cy...

Claude code is moving from a coder to a general assistant. Personally, sending sensitive data to someone's server isn't an option. But w/ ollama "launch" feature, I may do w/ local LLMs. Time for experiment! (reading while me being fed with a cup of Miso soup) www.dtlarson.com/feed-the-beast

Thrilled to share our new paper in Science @science.org: “Scientific Production in the era of Large Language Models.” - LLMs boost productivity, especially for non-native speakers. - Writing complexity is now "decoupled" from scientific quality. - LLMs help discover more diverse literature.

🧵1/ A bit late to the party, but I want to introduce a pet project of mine—and my first single-author paper! 🎉 It tackles something that has quietly frustrated me for years: how we measure the similarity of two clusterings/community structures.

Nano Banana Pro unbelievably lowers the entry barrier for people interested in creating short Manga. This blog post describes the recipe (in Japanese). I get this Manga version of my lecture note on the position encoding in transformers, **in the first shot** 😮. note.com/konho/n/na8d...

I'm looking for a PhD student to join my lab at UAlbany for Fall 2026! We are data scientists studying the creation, flow, and impact of information. How do scientists collaborate? How does AI shape information access? What drives local innovation? Want to answer these questions? details below!

🚨 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

TLDR: communities are undetectable even if they are because of the variabilities of network topology. We look further into edge weights, showing that a higher variability in edge weights makes communities harder to be detected. Our results inform when to use edge weights and better edge reweighing.

Is #innovation born or made? Why do some places keep innovating while others fall behind? Is innovation the product of cities—or of deeper laws? Our new paper in npj Complexity explores these questions through the lens of a century of US patent data.🧵👇 nature.com/articles/s44...

When are communities detectable in weighted networks? You can find the answer in our latest preprint. Great collaboration with @filipisilva.bsky.social @skojaku.bsky.social arxiv.org/abs/2511.00214

Snakemake is essential for reproducible research—it organizes code, and acts as my second brain about code and data relations. A downside is its maintenance cost. It can be easily convoluted as a project progresses. This tool might resolve that. arxiv.org/html/2505.02...

I've been playing with Ollama Cloud that has a free cloud Qwen 3 Vision Language model, which is surprisingly good. I put together a small app that automatically renames screenshot files based on their content, which has been super helpful for organizing them. github.com/skojaku/scre...
