Fig. 1. Strategy of network reconstruction from responses of time invariants.

(A) A networked dynamical system with unknown topology (gray) is perturbed by external driving signals I^m, m ∈ {1, …, M}. (B) Potentially noisy, disordered, low-resolution data are collected from several different experiments. (C) The centers of mass z^(m) of each of these distributions of points sampled in state space are calculated. (D) The changes ${\mathit{z}}_{\mathit{i}}^{(\mathit{m})}-{\mathit{z}}_{\mathit{i}}^{(0)}$ in response to driving signals I^(m) yield the network topology.
