Inferring signed social networks from contact patterns
Dávid Ferenczi, Jean-Gabriel Young, Leto Peel
Social networks are typically inferred from indirect observations, such as proximity data; yet, most methods cannot distinguish between absent relationships and actual negative tie…
Higher order trade-offs in hypergraph community detection
Jiaze Li, Michael T. Schaub, Leto Peel
Extending community detection from pairwise networks to hypergraphs introduces fundamental theoretical challenges. Hypergraphs exhibit structural heterogeneity with no direct graph…
Detectability of minority communities in networks
Jiaze Li, Leto Peel
Community structure is prevalent in real-world networks, with empirical studies revealing heterogeneous distributions where a few dominant majority communities coexist with many sm…
Academic collaborations and movements towards successful careers in physics
Mingrong She, Jan Bachmann, Fariba Karimi +1
Collaboration networks evolve throughout academic careers, yet few studies systematically examine how these network dynamics relate to long-term career success and mobility. Analys…
Graphs are maximally expressive for higher-order interactions
Tiago P. Peixoto, Leto Peel, Thilo Gross +1
We demonstrate that graph-based models are fully capable of representing higher-order interactions, and have a long history of being used for precisely this purpose. This stands in…
