The paper studies parameter identification in ordinary differential equation (ODE) models with time-varying parameters, using noisy and sparse observations. It proposes TVMAGI, a time-varying manifold-constrained Gaussian process inference method that places Gaussian process priors on system components and parameters and enforces ODE-consistent derivative behavior through manifold constraints, which avoids numerical integration and improves computation time; the approach also supports missing data or unobserved components and addresses identifiability via the Gaussian process prior. Three simulation examples, including an infectious disease compartmental model, are used to demonstrate robustness and efficiency compared with numerical integration and Bayesian filtering methods. The paper does not provide a specific stated limitation in the provided text beyond focusing on simulation demonstrations. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match related to biomedical dynamic-system modeling.

Abstract

Identification of parameters in ordinary differential equations (ODEs) is an important and challenging task when modeling dynamic systems in biomedical research and other scientific areas, especially with the presence of time-varying parameters. This article proposes a fast and accurate method, TVMAGI (Time-Varying MAnifold-constrained Gaussian process Inference), to estimate both time-constant and time-varying parameters in the ODE using noisy and sparse observation data. TVMAGI imposes a Gaussian process model over the time series of system components as well as time-varying parameters, and restricts the derivative process to satisfy ODE conditions. Consequently, TVMAGI completely bypasses numerical integration and achieves substantial savings in computation time. By incorporating the ODE structures through manifold constraints, TVMAGI enjoys a principled statistical construct under the Bayesian paradigm, which further enables it to handle systems with missing data or unobserved components. The Gaussian process prior also alleviates the identifiability issue often associated with the time-varying parameters in ODE. Unlike existing approaches, TVMAGI can be applied to general nonlinear systems without specific structural assumptions. Three simulation examples, including an infectious disease compartmental model, are provided to illustrate the robustness and efficiency of our method compared with numerical integration and Bayesian filtering methods.
