Community structure in real-world networks from a non-parametrical synchronization-based dynamical approach

Abstract: This work analyzes the problem of community structure in real-world networks based on the synchronization of nonidentical coupled chaotic Rössler oscillators each one characterized by a defined natural frequency, and coupled according to a predefined network topology. The interaction scheme contemplates an uniformly increasing coupling force to simulate a society in which the association between the agents grows in time. To enhance the stability of the correlated states that could emerge from the synchronizati… Show more

“…Another option would therefore be to employ asymmetrical measures, such as Granger and/or partial directed coherence, to construct effective connectivity models and determine whether healthy controls and patients showed different causal association resting measurements. Moreover, although our selection of coherence thresholds is consistent with one of the more common procedures in the literature, our thresholds could instead be determined by parameterless approaches derived from adaptive neighborhood algorithms (Moujahid et al, 2012). …”

“…A parameterless mechanism adapts the characteristic frequencies of coupled oscillators according to a dynamic connectivity matrix deduced from correlated data. [27] In Ref. [28], a generalized Kuramoto model is considered, the phases of the nodes are naturally separated into several clusters after a period of evolution, and each cluster corresponds to a community in the network.…”
