We apply the neural ODE to holographic QCD by regarding the weight functions as a bulk metric, and train the machine with lattice QCD data of chiral condensate at finite temperature. The machine finds consistent bulk geometry at various values of temperature and discovers the emergent black hole horizon in the holographic bulk automatically. The holographic Wilson loops calculated with the emergent machine-learned bulk spacetime have consistent temperature dependence of confinement and Debye-screening behavior. In machine learning models with physically interpretable weights, the neural ODE frees us from discretization artifact leading to difficult ingenuity of hyperparameters, and improves numerical accuracy to make the model more trustworthy.<\/jats:p>","DOI":"10.1088\/2632-2153\/abe527","type":"journal-article","created":{"date-parts":[[2021,2,10]],"date-time":"2021-02-10T22:44:33Z","timestamp":1612997073000},"page":"035011","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":23,"title":["Neural ordinary differential equation and holographic quantum chromodynamics"],"prefix":"10.1088","volume":"2","author":[{"given":"Koji","family":"Hashimoto","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5841-831X","authenticated-orcid":false,"given":"Hong-Ye","family":"Hu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4080-5340","authenticated-orcid":false,"given":"Yi-Zhuang","family":"You","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2021,5,12]]},"reference":[{"key":"mlstabe527bib1","doi-asserted-by":"publisher","DOI":"10.1103\/RevModPhys.91.045002","volume":"91","author":"Carleo","year":"2019","journal-title":"Rev.
