New paper! If you’ve got temporal interactions among two distinct sets of objects (i.e. customers and products they purchased online), here is a principled, nonparametric way to construct hypergraphs representing cohesive interaction structures in the data.

Thanks to SoBigData TNA access, I got the occasion to visit Giulio Rossetti at KDD Lab Pisa in Pisa during the last 3 weeks. Stay tuned to see the results! Spoiler: it is related to community detection and CDlib - Community Discovery Library.

Your network data might be characterized by higher-order structure, or maybe not.

Kudos to Valentina Pansanella that today successfully defended her PhD.
It was a real pleasure to supervise her during these last 3y. Ad Maiora!!
