Code

EPR

Code to reproduce paper results (or as close as possible, depending on data-availability). Each publication has a Jupyter notebook.

Mostly probabilistic/Bayesian ML for engineering applications, particularly performance and health monitoring. Scripts are provided to test and demonstrate the EPR module.

Notebooks for papers
