featureRankedList {sigFeature} | R Documentation |
The variable "featureRankedList" contains the output of the function named "svmrfeFeatureRanking()".
data("featureRankedList")
The format is: int [1:2204] 1073 1404 1152 5 1253 1557 105 1207 792 57 ...
To solve the classification problem with the help of ranking the features an algorithm was proposed by Guyon named SVM-RFE. In this algorithm the dataset has been trained with SVM linear kernel model and removed the feature with smallest ranking criterion. This criterion is the w value of the decision hyperplane given by the SVM.
