The JMLR LaTeX template enforces the use of {algorithm2e} to typeset algorithms, package I am not familiar withโmy weapon of choice is {algorithmicx}โyet I'm starting to see the appeal.
{algorithm2e} does provide you with more flexibility! For instance, the flexibility to wish you'd never been born

๐ We extend motif analysis to directed hypergraphs to detect recurring local structures, including feedback and reinforcement patterns.
๐ We propose three measures of higher-order reciprocity in directed hypergraphs: exact, strong, and weak. All systems show reciprocity, but the patterns vary across domains.
๐ฅ We analyze overlaps between source and target sets to track recurring co-senders and co-receivers. This lets us ask whether nodes sit in stable โteamsโ or keep reshuffling partners.
๐พ We introduce a fingerprint of directed hyperedge structure using source and target set-size patterns, then use it to compute distances between datasets. The similarities we find line up with domains.
We study directed higher-order interactions, where each interaction links a set of sources to a set of targets (many-to-many). This is the kind of interaction you get in emails, Bitcoin transactions, metabolic reactions, and citations. We ask how these systems are organized at the microscale.

When can higher-order networks be simplified without losing what matters?
New papers in @physrevlett.bsky.social and @natcomms.nature.com by Federico Battiston & collaborators introduce structural and dynamical reducibility frameworks for higher-order networks.

How complex should network models be?
๐จ In our latest paper we quantify (if and) when higher-order interactions are informative versus reducible to pairwise structure without losing functional signal (e.g., diffusion behavior).

๐จ๐จ New paper out! With @colltoaction.bsky.social, @fralotito.bsky.social, and a bunch of offline co-authors ๐ we published "HIF: The hypergraph interchange format for higher-order networks" doi.org/10.1017/nws....
At NetPlace, we try to build spaces for junior researchers to come together to learn from each other and develop their craft. Our seminar series does just this, integrating the sharing of scientific knowledge and discussion about the process of science. We hope Ph.D. students from complex systems, network science, and interdisciplinary research in general will join us for a monthly talk and discussion. Elena Candellone (Thursday, Oct. 2) Louis Boucherie (Thursday, Nov. 6) Haily Merritt (Thursday, Dec. 4)
Weโre excited to announce the line-up for our fall seminar series! We have three awesome speakers who will share their research and perspectives on the craft of science.
๐จ๐จ New preprint just dropped! In collaboration with @colltoaction.bsky.social, Cliff Joslyn, @fralotito.bsky.social, Audun Myers, Joshua Pickard, Brenda Praggastis, and Przemysลaw Szufel, we define a new data sharing standard for higher-order networks. arxiv.org/abs/2507.11520

Average day in AI discourse:
- The big tech paper saying LLMs are harmless toys,
- The influencer claiming LLMs are an existential threat.
The lovely Netplace people and their wonderful energy and ideas created some great opportunities for connections and engagement. It was really nice to work with them!
