When trying to calibrate to high-dimensional output (e.g., a spatial field), what is important to the credibility of the model is that key emergent physical phenomena are represented, even if not faithfully or in the right place. Commonly used approaches, which represent the output as a linear combination of a small set of basis vectors, often fail to appropriately compare model output and data when the position of key emergent phenomena shifts, consequently leading to poor model calibration. To overcome this, we present kernel-based history matching (KHM), generalizing the meaning of the technique sufficiently to be able to project model outputs and observations into a higher-dimensional feature space, where patterns can be compared without their location necessarily being fixed. We develop the technical methodology, present an expert-driven kernel selection algorithm, and then apply the techniques to the calibration of boundary layer clouds for the French climate model IPSL-CM.<\/jats:p>","DOI":"10.1137\/24m163253x","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T04:01:18Z","timestamp":1745553678000},"page":"591-612","source":"Crossref","is-referenced-by-count":0,"title":["Feature Calibration for Computer Models"],"prefix":"10.1137","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0227-1678","authenticated-orcid":true,"given":"Wenzhe","family":"Xu","sequence":"first","affiliation":[{"name":"School of Science, Beijing University of Posts and Telecommunications, Beijing, 100876 China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8917-3300","authenticated-orcid":true,"given":"Daniel B.","family":"Williamson","sequence":"additional","affiliation":[{"name":"Department of Mathematical Sciences, University of Exeter, UK and The Alan Turing Institute, The British Library, London, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederic","family":"Hourdin","sequence":"additional","affiliation":[{"name":"LMD-IPSL, Sorbonne University, CNRS, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romain","family":"Roehrig","sequence":"additional","affiliation":[{"name":"CNRM, Universit\u00e9 de Toulouse, M\u00e9t\u00e9o-France, CNRS, Toulouse, France."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"351","published-online":{"date-parts":[[2025,4,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1137\/16M1093008"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pcbi.1003968"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002\/2015WR016967"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1029\/2020MS002269"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.5194\/gmd-15-1913-2022"},{"key":"ref6","volume-title":"Pattern Recognition and Machine Learning","author":"Bishop C.
