At this point, I decided to first apply the linear SVM by tuning the parameters. The code looks like this: svm_model<-svm(MIS_Status~.,data=train_processed,kernel="linear")tune_result<-tune(svm,MIS_Status~.,data=train_processed,kernel="linear",ranges=list(cost=c(0.1,1...

In this paper, we propose a hybrid of support vector machine and smoothly clipped absolute deviation with group-specific tuning parameters (gSVM-SCAD) to select informative genes within pathways before the pathway evaluation process. Experiments conducted on gender and lung cancer datasets shows that ...
