The conference is officially underway – here are some moments from the opening session.

New preprint out! 📣 “Emerging Activity Temporal Hypergraph (EATH), a model for generating realistic time-varying hypergraphs” with @giuliacencetti.bsky.social and @alainbarrat.bsky.social arxiv.org/abs/2507.01124 How can we generate realistic time-varying hypergraphs? 1/8 🧵⬇️

Delighted to announce the #CCS25 Scientific Dissemination Event! 🌐Free public event in italian called "La complessità è semplice?" 📅 Wednesday, September 3rd, 20:30 📍Teatro dei Rinnovati in the Palazzo Pubblico of Siena 🔗 ccs25.cssociety.org/public-disse...

@xgi.bsky.social in the wild 👀

Cosimo giving a compelling overview of his pairwise and higher-order network comparison measures

@beyondtheedge.network student Cosimo Agostinelli presenting higher-order dissimilarity measures as a way to compare temporal snapshots, empirical data to synthetic null models, etc.

Very nice higher-order generative model to try and reproduce the empirical dynamics

The hypercoreness ranking correlation between two timestamps is strongly dependent on the timescale (negative correlations for long enough time gap)

@marco-mancastroppa.bsky.social talking about temporal evolution from the lens of "hypercores" --- a higher-order extension of the k-core measure for pairwise networks

Now out our new preprint “Higher-order dissimilarity measures for hypergraph comparison”! www.arxiv.org/abs/2503.16959 With Cosimo Agostinelli and @alainbarrat.bsky.social We extend to hypergraphs similarity measures defined previously only on pairwise networks. 🧵⬇️ 1/5

New work with @alainbarrat.bsky.social! How to generate surrogate temporal networks to replace real ones: arxiv.org/abs/2411.05477 Surrogates will have: - no temporal length limit - local dynamics similar to the real one - mesoscale features like clustering and modularity - long-term memory effects
