Query: Constrained information flows in temporal networks reveal intermittent
  communities   Many real-world networks represent dynamic systems with interactions that
change over time, often in uncoordinated ways and at irregular intervals. For
example, university students connect in intermittent groups that repeatedly
form and dissolve based on multiple factors, including their lectures,
interests, and friends. Such dynamic systems can be represented as multilayer
networks where each layer represents a snapshot of the temporal network. In
this representation, it is crucial that the links between layers accurately
capture real dependencies between those layers. Often, however, these
dependencies are unknown. Therefore, current methods connect layers based on
simplistic assumptions that do not capture node-level layer dependencies. For
example, connecting every node to itself in other layers with the same weight
can wipe out dependencies between intermittent groups, making it difficult or
even impossible to identify them. In this paper, we present a principled
approach to estimating node-level layer dependencies based on the network
structure within each layer. We implement our node-level coupling method in the
community detection framework Infomap and demonstrate its performance compared
to current methods on synthetic and real temporal networks. We show that our
approach more effectively constrains information inside multilayer communities
so that Infomap can better recover planted groups in multilayer benchmark
networks that represent multiple modes with different groups and better
identify intermittent communities in real temporal contact networks. These
results suggest that node-level layer coupling can improve the modeling of
information spreading in temporal networks and better capture intermittent
community structure.
