Selecting relevant genes for cancer classification is an important issue. Most of the gene selection methods use univariate ranking criteria and arbitrarily choose a threshold to choose genes. However, the parameter setting may not be compatible to the selected classification algorithms. In this paper, we propose a new gene selection method (SVM-<jats:italic>t<\/jats:italic>) based on the use of<jats:italic>t-<\/jats:italic>statistics embedded in support vector machine. We compared the performance to two similar SVM-based methods: SVM recursive feature elimination (SVMRFE) and recursive support vector machine (RSVM). The three methods were compared based on extensive simulation experiments and analyses of two published microarray datasets. In the simulation experiments, we found that the proposed method is more robust in selecting informative genes than SVMRFE and RSVM and capable to attain good classification performance when the variations of informative and noninformative genes are different. In the analysis of two microarray datasets, the proposed method yields better performance in identifying fewer genes with good prediction accuracy, compared to SVMRFE and RSVM.<\/jats:p>","DOI":"10.1155\/2012\/712542","type":"journal-article","created":{"date-parts":[[2012,8,15]],"date-time":"2012-08-15T17:00:58Z","timestamp":1345050058000},"page":"1-12","source":"Crossref","is-referenced-by-count":3,"title":["Recursive Feature Selection with Significant Variables of Support Vectors"],"prefix":"10.1155","volume":"2012","author":[{"given":"Chen-An","family":"Tsai","sequence":"first","affiliation":[{"name":"Department of Agronomy, National Taiwan University, Taipei 106, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chien-Hsun","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Statistics, Columbia University, New York, NY 10027, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching-Wei","family":"Chang","sequence":"additional","affiliation":[{"name":"Division of Personalized Nutrition and Medicine, National Center for Toxicological Research, Food and Drug Administration, Jefferson, AR 72079, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun-Houh","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Statistical Science, Academia Sinica, 128 Academia Road, Section 2, Taipei 115, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"doi-asserted-by":"publisher","key":"2","DOI":"10.1126\/science.286.5439.531"},{"issue":"10","key":"3","doi-asserted-by":"crossref","first-page":"906","DOI":"10.1093\/bioinformatics\/16.10.906","volume":"16","year":"2000","journal-title":"Bioinformatics"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1093\/bioinformatics\/bth267"},{"key":"5","series-title":"Studies in Fuzziness and Soft Computing","first-page":"315","volume-title":"Combining SVMs with various feature selection strategies","year":"2006"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1038\/ng1502"},{"key":"9","first-page":"1205","volume":"5","year":"2004","journal-title":"Journal of Machine Learning Research"},{"doi-asserted-by":"publisher","key":"10","DOI":"10.1073\/pnas.201162998"},{"doi-asserted-by":"publisher","key":"11","DOI":"10.1186\/1471-2105-7-3"},{"doi-asserted-by":"publisher","key":"12","DOI":"10.1007\/s13042-011-0061-9"},{"issue":"3","key":"13","first-page":"745","volume":"9","year":"2012","journal-title":"IEEE\/ACM Transactions on Computational Biology and Bioinformatics"},{"doi-asserted-by":"publisher","key":"14","DOI":"10.1093\/bioinformatics\/btm344"},{"year":"1999","key":"15"},{"doi-asserted-by":"publisher","key":"16","DOI":"10.1073\/pnas.97.1.262"},{"doi-asserted-by":"publisher","key":"17","DOI":"10.1023\/A:1012487302797"},{"doi-asserted-by":"publisher","key":"1","DOI":"10.1186\/1471-2105-7-197"},{"doi-asserted-by":"publisher","key":"18","DOI":"10.1109\/TNB.2005.853657"},{"doi-asserted-by":"publisher","key":"19","DOI":"10.1038\/nm733"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/712542.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/712542.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/712542.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,20]],"date-time":"2017-06-20T18:53:51Z","timestamp":1497984831000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2012\/712542\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":17,"alternative-id":["712542","712542"],"URL":"https:\/\/doi.org\/10.1155\/2012\/712542","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"type":"print","value":"1748-670X"},{"type":"electronic","value":"1748-6718"}],"subject":[],"published":{"date-parts":[[2012]]}}}
