Code for different emulation/calibration work

• code/ contains general emulation/calibration code used across multiple projects, including:

  • code/FastHM.R contains fast history matching code (for high dimensional output) from Salter & Williamson 2022 https://www.dl.begellhouse.com/journals/52034eb04b657aea,7ba373b25cc40b46,0c41fc6d5a39a9c2.html

  • code/rotation_functions.R contains main basis emulation code from Salter et al 2019 https://www.tandfonline.com/doi/shareview/10.1080/01621459.2018.1514306 Examples relating to this code are also in this folder, as well as wrappers for combining this code with RobustGasp and mogp_emulator (reproduced from old repository https://github.com/JSalter90/RotateBasis)

  • code/discrepancy.R (coming soon) will contain code for reframing history matching/calibration as a classification problem, with several worked toy examples

• applications/ contains specific applications , including:

  • applications/raikoke emulating the NAME volcanic ash dispersion model, https://acp.copernicus.org/articles/24/6251/2024/

  • application/SECRET pulmonary and systemic model emulation

  • application/SECRET/Example_EmulateTS.html A worked example of emulating high-dimensional output
