在物理、化學、生物的領域上,我們常常會用微分方程模型去描述自然的現象。而對於這樣一個微分方程模型,我們可能僅能觀測到裡面的其中某幾個參數。在這樣的情形底下,我們該如何去做微分方程模型的參數估計?這就是我們要討論的議題。在考慮到電腦計算的速度以及參數估計的精確度,本文以Hindmarsh-Rose Type model做為例子,提供了一套參數估計的方法。
In physics, chemistry and biology,
many researcher try to describe natural phenomena by ordinary differential equations (ODE)
due to the fact that a lot of elegant theorem can be found in ODE and its nonlinear properties.
With the observed information and some prior knowledge for a potential model,
parameter estimation of an ODE model often requires a lot of computation works,
such as a numerical integration of the ODE system and minimization of the log-likelihood function.
In this paper, we consider a partially observed ODE model: 2D-HR type model.
With the partially information, we present a simple way (iterative estimation process)
without too mach computation to estimate the parameters in this model.
