Local phase transitions in a model of multiplex networks with heterogeneous degrees and inter-layer coupling
Nedim Bayrakdar, Valerio Gemmetto, Diego Garlaschelli
Multilayer networks represent multiple types of connections between the same set of nodes. Clearly, a multilayer description of a system adds value only if the multiplex does not m…
Reconstruction of multiplex networks with correlated layers
Valerio Gemmetto, Diego Garlaschelli
The characterization of various properties of real-world systems requires the knowledge of the underlying network of connections among the system's components. Unfortunately, in ma…
Irreducible network backbones: unbiased graph filtering via maximum entropy
Valerio Gemmetto, Alessio Cardillo, Diego Garlaschelli
Networks provide an informative, yet non-redundant description of complex systems only if links represent truly dyadic relationships that cannot be directly traced back to node-spe…
ScienceWISE: Topic Modeling over Scientific Literature Networks
Andrea Martini, Artem Lutov, Valerio Gemmetto +11
We provide an up-to-date view on the knowledge management system ScienceWISE (SW) and address issues related to the automatic assignment of articles to research topics. So far, SW…
Ground truth? Concept-based communities versus the external classification of physics manuscripts
Vasyl Palchykov, Valerio Gemmetto, Alexey Boyarsky +1
Community detection techniques are widely used to infer hidden structures within interconnected systems. Despite demonstrating high accuracy on benchmarks, they reproduce the exter…
Multiplexity and multireciprocity in directed multiplexes
Valerio Gemmetto, Tiziano Squartini, Francesco Picciolo +2
Real-world multi-layer networks feature nontrivial dependencies among links of different layers. Here we argue that, if links are directed, dependencies are twofold. Besides the or…
Multiplexity versus correlation: the role of local constraints in real multiplexes
Valerio Gemmetto, Diego Garlaschelli
Several real-world systems can be represented as multi-layer complex networks, i.e. in terms of a superposition of various graphs, each related to a different mode of connection be…
Mitigation of infectious disease at school: targeted class closure vs school closure
Valerio Gemmetto, Alain Barrat, Ciro Cattuto
School environments are thought to play an important role in the community spread of airborne infections (e.g., influenza) because of the high mixing rates of school children. The…
