Summary: Support vector machine (SVMs) classification is a widely used and one of the most powerful classification techniques. However, a major limitation is that SVM cannot perform automatic gene selection. To overcome this restriction, a number of penalized feature selection methods have been proposed. In the R package penalizedSVM implemented penalization functions L1 norm and Smoothly Clipped Absolute Deviation (SCAD) provide automatic feature selection for SVM classification tasks.
Availability: The R package penalizedSVM is available from the Comprehensive R Archive Network (http://cran.r-project.org/) under GPL-2 or later.
