rkg3: The 'rkg3' class object

In KGode: Kernel Based Gradient Matching for Parameter Inference in Ordinary Differential Equations

The 'rkg3' class object

Description

This class provides advanced gradient matching method by using the ode as a regularizer.

Format

R6Class object.

Value

an R6Class object which can be used for improving ode parameters estimation by using ode as a regularizer.

Methods

iterate(iter,innerloop,lamb)

Iteratively updating ode parameters and interpolation regression coefficients.

witerate(iter,innerloop,dtilda,lamb)

Iteratively updating ode parameters and the warped interpolation regression coefficients.

full(par,lam)

Updating ode parameters and rkhs interpolation regression coefficients simultaneously. This method is slow but guarantee convergence.

Public fields

rk

the 'rkhs' class object containing the interpolation information for each state of the ode.

ode_m

the 'ode' class object containing the information about the odes.

Active bindings

ode_m

the 'ode' class object containing the information about the odes.
