wmin-model is a Colibri PDF-model that implements the Proper Orthogonal Decomposition (POD) parametrisation presented in arXiv:2507.16913.

Primary Workflows:

PDF Fits with POD Parametrisation: Perform parton distribution function (PDF) fits on NNPDF data using the Colibri Bayesian workflow and the linear POD parametrisation.
POD-Basis Construction: Generate a Proper Orthogonal Decomposition (POD) basis.

wmin-model implements the NNPOD methodology, providing a linear PDF model optimized for Bayesian inference in high-energy physics.

Installation:

git clone https://github.com/HEP-PBSP/wmin-model.git
cd wmin-model
conda env create -f environment.yml
