The major challenge in processing these signals is the extraction of the global characteristics of the data due to their huge dimension and the complex relationship among various genes. Statistical methods are used in broad spectrum in this domain. But, various limitations like extensive preprocessing, noise sensitiveness, requirement of critical input parameters and prior knowledge about the microarray dataset emphasise the need for better exploratory techniques. Transform oriented signal processing techniques are successful in many data processing techniques like image and video processing. But, the use of wavelets in analyzing the microarray bio-signals is not sufficiently probed. The aim of this paper is to propose a wavelet power spectrum based technique for dimensionality reduction through gene selection and classification problem of gene microarray data. The proposed method was administered on such datasets and the results are encouraging. The present method is robust to noise since no preprocessing has been applied. Also, it does not require any critical input parameters or any prior knowledge about the data which is required in many existing methods.<\/jats:p>","DOI":"10.1142\/s0219691308002409","type":"journal-article","created":{"date-parts":[[2008,4,29]],"date-time":"2008-04-29T10:36:48Z","timestamp":1209465408000},"page":"375-389","source":"Crossref","is-referenced-by-count":5,"title":["A WAVELET APPROACH FOR CLASSIFICATION OF MICROARRAY DATA"],"prefix":"10.1142","volume":"06","author":[{"given":"S.","family":"PRABAKARAN","sequence":"first","affiliation":[{"name":"Indian Institute of Information Technology and Management, Gwalior, India"}]},{"given":"R.","family":"SAHU","sequence":"additional","affiliation":[{"name":"Indian Institute of Information Technology and Management, Gwalior, India"}]},{"given":"S.","family":"VERMA","sequence":"additional","affiliation":[{"name":"Indian Institute of Information Technology and Management, Gwalior, India"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"crossref","first-page":"1072","DOI":"10.1681\/ASN.V1251072","volume":"12","author":"Kurella M.","journal-title":"J.
