Introduction

In recent years, the field of machine learning (ML) has made significant strides in various applications, including the estimation of parameters in complex systems. One such system is the coupled ordinary differential equation (ODE), which is widely used to model various phenomena in physics, biology, and engineering. However, estimating the parameters of a coupled ODE can be a challenging task, especially when dealing with noisy and incomplete data. In this article, we will discuss the dynamic parameter estimation of coupled ODE on time-series data using ML methods.

Background

Coupled ODEs are a class of mathematical models that describe the behavior of complex systems by representing the interactions between different components. These models are widely used in various fields, including physics, biology, and engineering, to study the behavior of complex systems. However, estimating the parameters of a coupled ODE can be a challenging task, especially when dealing with noisy and incomplete data.

SINDy: A Method for Identifying Coupled ODEs

SINDy (Sparse Identification of Nonlinear Dynamics) is a method for identifying coupled ODEs from time-series data. This method uses a combination of sparse regression and machine learning techniques to identify the nonlinear dynamics of a system from a set of time-series data. SINDy has been widely used in various applications, including the study of complex systems in physics, biology, and engineering.
