Therefore, a new method of multilayer nonnegative matrix factorization (NMF) in this paper is put forward, taking the hump shape J wave, for example, which can extract the original J wave signal from the ST segment and analyze the accuracy of extraction, showing the characteristics of hump shape J wave from the aspects of frequency domain, power spectrum, and spectral type, providing the basis for clinical diagnosis and increasing the reliability of the diagnosis of J wave.<\/jats:p>","DOI":"10.1155\/2014\/217067","type":"journal-article","created":{"date-parts":[[2014,10,12]],"date-time":"2014-10-12T17:01:59Z","timestamp":1413133319000},"page":"1-8","source":"Crossref","is-referenced-by-count":4,"title":["An Effective Way of J Wave Separation Based on Multilayer NMF"],"prefix":"10.1155","volume":"2014","author":[{"given":"Deng-ao","family":"Li","sequence":"first","affiliation":[{"name":"College of Information Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing-ang","family":"Lv","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ju-min","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"1","key":"1","first-page":"50","volume":"13","year":"1999","journal-title":"China Cardiac Pacemaker and Electrophysiology"},{"key":"2","first-page":"3","volume":"1","year":"2007","journal-title":"Journal of Clinical Electrocardiology"},{"issue":"6","key":"3","first-page":"360","volume":"8","year":"2004","journal-title":"Chinese Journal of Cardiac Arrhythmias"},{"issue":"6","key":"4","first-page":"1049","volume":"32","year":"2010","journal-title":"Piezoelectrics and Acoustooptics"},{"doi-asserted-by":"publisher","key":"5","DOI":"10.1046\/j.1540-8167.2003.02382.x"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1109\/TNN.2003.810616"},{"doi-asserted-by":"publisher","key":"9","DOI":"10.1109\/TPAMI.2006.60"},{"key":"10","series-title":"Lecture Notes in Computer Science","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1007\/11818564_17","volume-title":"Blind separation of multichannel biomedical image patterns by non-negative least-correlated component analysis","volume":"4146","year":"2006"},{"doi-asserted-by":"publisher","key":"11","DOI":"10.1109\/TSP.2013.2287683"},{"key":"8","first-page":"1457","volume":"5","year":"2004","journal-title":"Journal of Machine Learning Research"},{"doi-asserted-by":"publisher","key":"12","DOI":"10.1155\/2013\/896056"},{"doi-asserted-by":"publisher","key":"13","DOI":"10.1049\/el:20060983"},{"doi-asserted-by":"publisher","key":"14","DOI":"10.1142\/S0129065707001275"},{"doi-asserted-by":"publisher","key":"15","DOI":"10.1007\/s11063-009-9114-4"},{"doi-asserted-by":"publisher","key":"16","DOI":"10.1155\/2014\/953745"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2014\/217067.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2014\/217067.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2014\/217067.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T18:16:28Z","timestamp":1498155388000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2014\/217067\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":15,"alternative-id":["217067","217067"],"URL":"https:\/\/doi.org\/10.1155\/2014\/217067","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"type":"print","value":"1748-670X"},{"type":"electronic","value":"1748-6718"}],"subject":[],"published":{"date-parts":[[2014]]}}}
