Operator Fitting for Parameter Estimation of Stochastic Differential Equations

  journal={arXiv: Statistics Theory},
Estimation of parameters is a crucial part of model development. When models are deterministic, one can minimise the fitting error; for stochastic systems one must be more careful. Broadly parameterisation methods for stochastic dynamical systems fit into maximum likelihood estimation- and method of moment-inspired techniques. We propose a method where one matches a finite dimensional approximation of the Koopman operator with the implied Koopman operator as generated by an extended dynamic…

Parameter Estimation and Identification of Nonlinear Systems with the Koopman Operator

This framework is based on the key idea that nonlinear system identification in the state space is equivalent to linear identification of the Koopman operator in the space of observables and is shown to be efficient with a general class of systems, including chaotic systems, and well suited to low sampling rate datasets.

Extracting stochastic governing laws by non-local Kramers–Moyal formulae

This work uses the normalizing flows technology to estimate the transition probability density function from data, and substitutes it into the recently proposed non-local Kramers–Moyal formulae to approximate Lévy jump measure, drift coefficient and diffusion coefficient, and demonstrates that this approach can learn the stochastic differential equation with LÉvy motion.

Discovering transition phenomena from data of stochastic dynamical systems with Lévy noise.

The purpose of this present work is to extract information about transition phenomena from data of stochastic differential equations with non-Gaussian Lévy noise by using the relation between the stochastics Koopman semigroup and the infinitesimal generator of a stochastically differential equation to learn the mean exit time and escape probability from data.

Identification of Nonlinear Systems Using the Infinitesimal Generator of the Koopman Semigroup—A Numerical Implementation of the Mauroy–Goncalves Method

The subtle numerical details of the Koopman operator-based linearization method are addressed and a new implementation algorithm is proposed that alleviates these problems.

Koopman-Based Lifting Techniques for Nonlinear Systems Identification

A novel lifting technique for nonlinear system identification based on the framework of the Koopman operator is developed, an indirect method that does not require to compute time derivatives and is therefore well-suited to low-sampling rate data sets.

Introduction to the Koopman Operator in Dynamical Systems and Control Theory

This introductory chapter provides an overview of the Koopman operator framework. We present basic notions and definitions, including those related to the spectral properties of the operator. We also

Learning the temporal evolution of multivariate densities via normalizing flows

This work proposes a method to learn multivariate probability distributions using sample path data from stochastic differential equations and demonstrates that this approach can approximate probability density function evolutions in time from observed sampled data for systems driven by both Brownian and Lévy noise.

The aim of the Optim package is to enable researchers, users, and other Julia packages to solve optimization problems without writing such algorithms themselves.



Parameter estimation for differential equations: a generalized smoothing approach

A new method that uses noisy measurements on a subset of variables to estimate the parameters defining a system of non‐linear differential equations, based on a modification of data smoothing methods along with a generalization of profiled estimation is described.

A Data–Driven Approximation of the Koopman Operator: Extending Dynamic Mode Decomposition

This approach is an extension of dynamic mode decomposition (DMD), which has been used to approximate the Koopman eigenvalues and modes, and if the data provided to the method are generated by a Markov process instead of a deterministic dynamical system, the algorithm approximates the eigenfunctions of the Kolmogorov backward equation.

On the selection of ordinary differential equation models with application to predator‐prey dynamical models

The resulting method is shown to be an (asymptotically) oracle model selection method that selects the best predator‐prey ODE to model a lynx and hare population dynamical system among some well‐known and biologically interpretable ODE models.

Parameter estimation in ordinary differential equations for biochemical processes using the method of multiple shooting.

In silico investigations by simulating dynamical models of biochemical processes play an important role in systems biology and the literature regarding the practical implementation and providing some theoretical background is rarely available.

Bayesian parameter inference for stochastic biochemical network models using particle Markov chain Monte Carlo

Inference for the parameters of complex nonlinear multivariate stochastic process models is a challenging problem, but it is found here that algorithms based on particle Markov chain Monte Carlo turn out to be a very effective computationally intensive approach to the problem.
