BayesValidRox

An open-source, object-oriented Python package for surrogate-assisted Bayesain Validation of computational models. This framework provides an automated workflow for surrogate-based sensitivity analysis, Bayesian calibration, and validation of computational models with a modular structure.

Features

• Surrogate modeling with Polynomial Chaos Expansion
• Global sensitivity analysis using Sobol Indices
• Bayesian calibration with MCMC using emcee package
• Bayesian validation with model weights for multi-model setting

Installation

The best practive is to create a virtual environment and install the package inside it.

To create and activate the virtual environment run the following command in the terminal:

  python3 -m venv bayes_env
  cd bayes_env
  source bin/activate

You can replace bayes_env with your preferred name. For more information on virtual environments see this link.

Now, you can install the latest release of the package on PyPI inside the venv with:

  pip install bayesvalidrox

and installing the version on the master branch can be done by cloning this repo and installing:

  git clone https://git.iws.uni-stuttgart.de/inversemodeling/bayesvalidrox.git
  cd bayesvalidrox
  pip install .
