Abstract: This work proposes a method for estimating the weight distribution of a network with Gauss edge weights using a time series collected from controlled measurements of the stable dynamics of the network. Comparing the weight distribution obtained using this method with that using another scheme demonstrates that the former is effective and accurate for estimating the weight distributionP(w)of coupled oscillator networks in a broad coupling strength region. This method enables the topological properties of underlying networks to be determined from only a time series of measurements because it depends on no prior information about the dynamical system. In addition, the method is rather robust against noise.
