Reconstruction of Ordinary Differential Equations From Time Series Data

  title={Reconstruction of Ordinary Differential Equations From Time Series Data},

  journal={arXiv: Data Analysis, Statistics and Probability},
We develop a numerical method to reconstruct systems of ordinary differential equations (ODEs) from time series data without {\it a priori} knowledge of the underlying ODEs using sparse basis learning and sparse function reconstruction. We show that employing sparse representations provides more accurate ODE reconstruction compared to least-squares reconstruction techniques for a given amount of time series data. We test and validate the ODE reconstruction method on known 1D, 2D, and 3D systems…

Predicting dynamical system evolution with residual neural networks
It is shown how by training neural networks with ResNet-like architecture on the solution samples, models can be developed to predict the ODE system solution further in time and the predicted solution remains stable for much longer times than for other currently known models.
Neural ordinary differential equations for ecological and evolutionary time‐series analysis
Inferring the functional shape of ecological and evolutionary processes from time‐series data can be challenging because processes are often not describable with simple equations. The dynamical

A regression method based upon group sparsity that is capable of discovering parametrized governing dynamical equations of motion of a given system by time series measurements is proposed, giving a promising new technique for disambiguating governing equations from simple parametric dependencies in physical, biological and engineering systems.
Flexible Model Induction through Heuristic Process Discovery
This paper describes FPM, a system that implementsuctive process modeling by composing knowledge about algebraic rate expressions and about conceptual processes like predation and remineralization in ecology, and compares its failure-driven approach with a naive scheme that generates all possible processes at the outset.


Equations of Motion from a Data Series
A method to reconstruct the deterministic portion of the equations of motion directly from a data series to represent a vast reduction of a chaotic data set’s observed complexity to a compact, algorithmic specification is described.
Automated reverse engineering of nonlinear dynamical systems
This work introduces for the first time a method that can automatically generate symbolic equations for a nonlinear coupled dynamical system directly from time series data, applicable to any system that can be described using sets of ordinary nonlinear differential equations.

It is claimed that the problem of estimating parameters in systems of ordinary differential equations which give rise to chaotic time series is naturally tackled by boundary value problem methods and Lyapunov exponents can be computed accurately from time series much shorter than those required by previous methods.
Synchronization of Lorenz-based chaotic circuits with applications to communications
An analogy between synchronization in chaotic systems, nonlinear observers for deterministic systems, and state estimation in probabilistic systems is established and the performance of the Lorenz SCS is compared to an extended Kalman filter for providing state estimates when the measurement consists of a single noisy transmitter component.
Deterministic nonperiodic flow
Finite systems of deterministic ordinary nonlinear differential equations may be designed to represent forced dissipative hydrodynamic flow. Solutions of these equations can be identified with
Distilling Free-Form Natural Laws from Experimental Data
This work proposes a principle for the identification of nontriviality, and demonstrated this approach by automatically searching motion-tracking data captured from various physical systems, ranging from simple harmonic oscillators to chaotic double-pendula, and discovered Hamiltonians, Lagrangians, and other laws of geometric and momentum conservation.
Precise Undersampling Theorems
The phase transition approach is reviewed here and the broad range of cases where it applies is described, including exceptions and state challenge problems for future research.
