Simultaneous Identification of Changepoints and Model Parameters in Switching Dynamical Systems

This repository contains the code for the paper Xiaoming Fu et al. "Simultaneous Identification of Changepoints and Model Parameters in Switching Dynamical Systems" (2024). To run the code repository locally, please check the Project.toml file for the required packages and install them in your local Julia environment.

Structure

scripts/Bayesian_ChangePointStudy main scripts to run the Bayesian inference for the models in the paper.
scripts/plot_scripts scripts to generate the figures in the paper.
src main Julia code used to build the ode models, adjoint sensitivity analysis, and Bayesian inference. Some of the code that calculates gradient information of the parameters are adapted from the SciMLSensitivity.jl with copyright Copyright (c) 2016-2020: ChrisRackauckas, Julia Computing.
data directory to save the generated simulation data and the raw data from covid-19-data.
test directory to run the tests for the correctness of reverse-mode AD and the gradient calculation of the parameters.
