One advantage of the ESMD method is to determine an optimal global mean curve in an adaptive way which is better than the common least-square method and running-mean approach; another one is to determine the instantaneous frequency and amplitude in a direct way which is better than the Hilbert-spectrum method. These will improve the adaptive analysis of the data from atmospheric and oceanic sciences, informatics, economics, ecology, medicine, seismology, and so on. <\/jats:p>","DOI":"10.1142\/s1793536913500155","type":"journal-article","created":{"date-parts":[[2013,8,29]],"date-time":"2013-08-29T04:29:08Z","timestamp":1377750548000},"page":"1350015","source":"Crossref","is-referenced-by-count":103,"title":["EXTREME-POINT SYMMETRIC MODE DECOMPOSITION METHOD FOR DATA ANALYSIS"],"prefix":"10.1142","volume":"05","author":[{"given":"JIN-LIANG","family":"WANG","sequence":"first","affiliation":[{"name":"College of Science, Qingdao Technological University, East Jialingjiang Road 777, Huangdao Region of Qingdao 266520, P.
