The algorithm (1) determines an appropriate piecewise linear network (PLN) model by cross validation, (2) applies the orthonormal least square (OLS) procedure to the PLN model utilizing a Modified Schmidt procedure, and (3) uses a floating search algorithm to select features that minimize the output variance. The undesirable \"nesting effect\" is prevented by the floating search approach, and the piecewise linear OLS procedure makes this algorithm very computationally efficient because the Modified Schmidt procedure only requires one data pass during the whole searching process. The selected features are compared to those obtained by other methods, through cross validation with support vector machines (SVMs).<\/jats:p>","DOI":"10.1142\/s021821300600303x","type":"journal-article","created":{"date-parts":[[2006,12,15]],"date-time":"2006-12-15T11:50:55Z","timestamp":1166183455000},"page":"893-915","source":"Crossref","is-referenced-by-count":9,"title":["AN EFFICIENT FEATURE SELECTION ALGORITHM FOR COMPUTER-AIDED POLYP DETECTION"],"prefix":"10.1142","volume":"15","author":[{"given":"JIANG","family":"LI","sequence":"first","affiliation":[{"name":"Clinical Center, National Institutes of Health, Bethesda, MD 20892-1182, USA"}]},{"given":"JIANHUA","family":"YAO","sequence":"additional","affiliation":[{"name":"Clinical Center, National Institutes of Health, Bethesda, MD 20892-1182, USA"}]},{"given":"RONALD M.","family":"SUMMERS","sequence":"additional","affiliation":[{"name":"Clinical Center, National Institutes of Health, Bethesda, MD 20892-1182, USA"}]},{"given":"NICHOLAS","family":"PETRICK","sequence":"additional","affiliation":[{"name":"NIBIB\/CDRH, Joint Laboratory for the Assessment of Medical Imaging System, FDA, HFZ-140, 12720 Twinbrook Parkway, Rockville, MD 20852, USA"}]},{"given":"MICHAEL T.","family":"MANRY","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, Arlington, Texas, 76019, USA"}]},{"given":"AMY K.","family":"HARA","sequence":"additional","affiliation":[{"name":"Mayo Clinic Scottsdale, Scottsdale, AZ, USA"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2252011619"},{"key":"rf3","doi-asserted-by":"crossref","DOI":"10.1093\/oso\/9780198538493.001.0001","volume-title":"Neural networks for pattern recognition","author":"Bishop C.","year":"1995"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1016\/S0004-3702(97)00043-X"},{"key":"rf6","first-page":"81","volume":"1","author":"Quinlan J.
