Query: Effective phase connectivity from observations   We present a novel approach for recovery of the directional connectivity of a
small oscillator network by means of the phase dynamics reconstruction from
multivariate time series data. The main idea is to use a triplet analysis
instead of the traditional pair-wise one. Our technique reveals effective phase
connectivity which is generally not equivalent to structural one. We
demonstrate that by comparing the coupling functions from all possible triplets
of oscillators, we are able to achieve in the reconstruction a good separation
between existing and non-existing connections, and thus reliably reproduce the
network structure.
