The paper addresses this problem and presents an efficient solution through a combination of empirical mode decomposition (EMD) and kernel independent component analysis (KICA) methods. The nonlinear mixture signals are firstly decomposed into a set of intrinsic mode function (IMF) components using EMD, which can be combined with the original observed signals to construct a set of new signals. Thus, the original problem can be effectively transformed into a problem of over-determined BSS, which can be solved by the use of KICA. The adoption of particle swarm optimization (PSO) algorithm can further enhance the performance of the EMD\u2013KICA solution. The proposed solution is assessed through a set of simulation experiments and the numerical results demonstrate its effectiveness.<\/jats:p>","DOI":"10.1177\/0142331217691336","type":"journal-article","created":{"date-parts":[[2017,3,15]],"date-time":"2017-03-15T20:01:31Z","timestamp":1489608091000},"page":"1836-1845","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Particle swarm optimization-based empirical mode decomposition\u2013kernel independent component analysis joint approach for diagnosing wind turbine gearbox with multiple faults"],"prefix":"10.1177","volume":"40","author":[{"given":"Qian","family":"Yang","sequence":"first","affiliation":[{"name":"College of Electrical Engineering, Zhejiang University, Hangzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiang","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering, Zhejiang University, Hangzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miaoying","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering, Zhejiang University, Hangzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjun","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering, Zhejiang University, Hangzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,3,15]]},"reference":[{"key":"bibr1-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsv.2015.10.028"},{"key":"bibr2-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1109\/TIA.2015.2413963"},{"key":"bibr3-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.conengprac.2013.06.017"},{"key":"bibr4-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1109\/TNN.2005.849840"},{"key":"bibr5-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijhydene.2014.04.205"},{"key":"bibr6-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymssp.2012.09.015"},{"key":"bibr7-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2007.10.023"},{"key":"bibr8-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2015.2412913"},{"key":"bibr9-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2012.06.013"},{"key":"bibr10-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymssp.2011.02.017"},{"key":"bibr11-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2013.07.007"},{"issue":"1","key":"bibr12-0142331217691336","first-page":"195","volume":"9","author":"Liu XP","year":"2013","journal-title":"Journal of Computational Information Systems"},{"key":"bibr13-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1007\/s11721-009-0034-8"},{"key":"bibr14-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijhydene.2013.12.195"},{"key":"bibr15-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmecsci.2013.01.035"},{"key":"bibr16-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2012.01.047"},{"key":"bibr17-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1109\/78.542183"},{"key":"bibr18-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1109\/TEC.2006.889614"},{"key":"bibr19-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymssp.2010.10.002"},{"issue":"1","key":"bibr20-0142331217691336","first-page":"921","volume":"15","author":"Sprekeler H","year":"2014","journal-title":"The Journal of Machine Learning Research"},{"key":"bibr21-0142331217691336","doi-asserted-by":"publisher","DOI":"10.1016\/j.renene.2010.05.012"},{"key":"bibr22-0142331217691336","unstructured":"U.S. Department of Energy (2015) Statistics show bearing problems cause the majority of wind turbine gearbox failures.
