However, when applied across diverse systems and processes, biasing protocols often require time- and resource-consuming fine-tuning. In search of robustness, we automate a prominent biasing method, Umbrella Sampling, by leveraging the Umbrella Integration formalism for free-energy calculation. To estimate the value of an integral, i.e., the free energy, our Bayesian Umbrella Quadrature (BUQ) method iteratively selects gradient samples, i.e., bias locations, that most reduce the posterior integral variance based on a noise-tolerant Gaussian process model, which also effectively interpolates between samples. We validate the method for a conformational change in a small peptide, a water-to-ice phase transition, and a substitution chemical reaction; demonstrating that BUQ provides an automated free-energy calculation framework that is accurate and robust across fundamentally different systems and processes. To ease adoption, we interface BUQ with widespread simulation packages and share hyperparametrization guidelines.<\/jats:p>","DOI":"10.1021\/acs.jctc.6c00120","type":"journal-article","created":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T10:55:36Z","timestamp":1781175336000},"page":"9332-9342","source":"Crossref","is-referenced-by-count":1,"title":["Bayesian Umbrella\nQuadrature Automates Free-Energy\nCalculations Across Diverse Molecular Systems and Processes"],"prefix":"10.1021","volume":"22","author":[{"given":"Eline K.","family":"Kempkes","sequence":"first","affiliation":[{"name":"University of Amsterdam , , Science Park 904 , ,","place":["Amsterdam, The Netherlands, 1098 XH"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4776-5521","authenticated-orcid":true,"given":"Alberto","family":"Pe\u0301rez de Alba Orti\u0301z","sequence":"additional","affiliation":[{"name":"University of Amsterdam , , Science Park 904 , ,","place":["Amsterdam, The Netherlands, 1098 XH"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,6,11]]},"reference":[{"key":"2026092209070148200_cit1","doi-asserted-by":"publisher","first-page":"459","DOI":"10.1063\/1.1730376","article-title":"Studies\nin molecular dynamics.
