We systematically develop a technique for reconstructing the phase dynamics equations for coupled oscillators from data. For autonomous oscillators and for two interacting oscillators we demonstrate how phase estimates obtained from general scalar observables can be transformed to genuine phases. This allows us to obtain an invariant description of the phase dynamics in terms of the genuine, observable-independent phases. We discuss the importance of this transformation for characterization of… 

Reconstruction of two-dimensional phase dynamics from experiments on coupled oscillators.

It is shown that the two-dimensional approach reveals behavior not detected by the one-dimensional model in a driven experimental oscillator, and the dependence of the coupling functions on the coupling magnitude and coupling time delay is quantified.

Reconstructing phase dynamics of oscillator networks.

This work generalizes the recent approach to the reconstruction of phase dynamics of coupled oscillators from data to cover the case of small networks of coupled periodic units and first reconstruct genuine phases and then obtain the coupling functions in terms of these phases.

Phase Coupling Estimation from Multivariate Phase Statistics

This work derives a closed-form solution for estimating the phase coupling parameters from observed phase statistics and derives a regularized solution to the estimation and shows that the resulting procedure improves performance when only a limited amount of data is available.

High-order phase reduction for coupled oscillators

We explore the phase reduction in networks of coupled oscillators in the higher orders of the coupling parameter. For coupled Stuart–Landau oscillators, where the phase can be introduced explicitly,

Dynamical Bayesian inference of time-evolving interactions: from a pair of coupled oscillators to networks of oscillators.

A method based on dynamical Bayesian inference that facilitates the simultaneous detection of time-varying synchronization, directionality of influence, and coupling functions can distinguish unsynchronized dynamics from noise-induced phase slips and is generalized to encompass networks of interacting oscillators and thus demonstrates its applicability to small-scale networks.

Experimental study of synchronization of coupled electrical self-oscillators and comparison to the Sakaguchi-Kuramoto model.

The collective phase dynamics of Wien-bridge oscillators coupled resistively are explored, and it is shown that the coupling can be quantitatively described by Sakaguchi's modification to the Kuramoto model.

Efficient determination of synchronization domains from observations of asynchronous dynamics.

Reconstructing the phase dynamics from data, this work successfully determine synchronization domains of noisy and chaotic oscillators by developing an approach for a fast experimental inference of synchronization properties of an oscillator.

Extracting phase coupling functions between networks of dynamical elements that exhibit collective oscillations: Direct extraction from time-series data

Many real-world systems are often regarded as weakly coupled limit-cycle oscillators, in which each oscillator corresponds to a dynamical system with a large number of degrees of freedom exhibiting

Reconstruction of Phase Dynamics from Macroscopic Observations Based on Linear and Nonlinear Response Theories

We propose a novel method to reconstruct phase dynamics equations from responses in macroscopic variables to weak inputs. Developing linear and nonlinear response theories in coupled

Coupling functions in networks of oscillators

Networks of interacting oscillators abound in nature, and one of the prevailing challenges in science is how to characterize and reconstruct them from measured data. We present a method of



Uncovering interaction of coupled oscillators from data.

A technique for reconstructing the phase dynamics equations for weakly coupled oscillators from data is developed and it is demonstrated that natural frequencies of oscillators can be recovered if several observations of coupled systems at different coupling strengths are available.

An approach is presented for extracting phase equations from multivariate time series data recorded from a network of weakly coupled limit cycle oscillators. Our aim is to estimate important

Determination of a coupling function in multicoupled oscillators.

A new method to determine a coupling function in a phase model is theoretically derived for coupled self-sustained oscillators and applied to Belousov-Zhabotinsky (BZ) oscillators. The synchronous

The experiment-based model properly describes in-phase and antiphase mutual entrainment with positive and negative interactions in small sets as well as dynamical clustering in populations of oscillators.

Inferring Asymmetric Relations between Interacting Neuronal Oscillators

A pilot study in one healthy subject reveals that asymmetry of interactions between different brain areas may strongly change with the transition from external to internal pacing, while the degree of synchronization hardly changes.

Estimation of delay in coupling from time series.

It is demonstrated that a time delay in weak coupling between two self-sustained oscillators can be estimated from the observed time series data and analytically and numerically that irregularity of the phase dynamics is essential for determination of the delay.

Estimation of coupling between time-delay systems from time series.

The method allows one to detect the presence of certain types of linear coupling between two time- delay systems, to define the type, strength, and direction of coupling, and to recover the model equations of coupled time-delay systems from chaotic time series corrupted by noise.
