This repository contains several methods to estimate the catalyst activity of a chemical reactor.

• Linear System Identification approach.
• Gaussian Process bases system identification using Reduced Rank method.
• Partial differential equation parameter estimation with latent force.

To use this package, please install the following prerequisities:

1. SIPPY package from github. Follow the instruction there.
2. Numba version should be later than 0.47.
3. Pytorch
4. tqdm

Explanation of files and folders:

1. Documentation contains a pdf file related to the PDE approach.
2. Python Notebook is the folder where all python notebook can be found.
3. chemReactor.py is the file that runs the finite rank GP system identification.
4. finiteDimensionalGP is a library that contains classes for finite rank GP system identification.
5. GPutils.py is a numerical library that is used in chemReactor.py.
6. PDE.py is a numerical library that is used in a Python notebook about PDE approach.
7. finiteRankGPsysID_example.py is the test file which runs the finite rank GP system identification for a toy model.
