In addition, the block count sketch Kaczmarz (BCSK) algorithm is also given, which selects multiple different rows simultaneously at each iteration. We prove that our methods converge to the unique solution of the linear systems. Finally, the numerical experiments show the high efficiency and robustness of our methods.<\/jats:p>","DOI":"10.3233\/faia231071","type":"book-chapter","created":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T15:09:40Z","timestamp":1702566580000},"source":"Crossref","is-referenced-by-count":0,"title":["Two Count Sketch Kaczmarz Algorithms for Linear Systems"],"prefix":"10.3233","author":[{"given":"Yikang","family":"Wang","sequence":"first","affiliation":[{"name":"School of Science, Chongqing University of Posts and Telecommunications, Chongqing, 400065"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pingping","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Science, Chongqing University of Posts and Telecommunications, Chongqing, 400065"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Fuzzy Systems and Data Mining IX"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA231071","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T15:09:41Z","timestamp":1702566581000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA231071"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,12]]},"ISBN":["9781643684703","9781643684710"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia231071","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,12,12]]}}}
