Re: [R] Hello all, How can I get corss-validation MSE of SVM in e1071?

The caret package is so good, I am learning it, but one problem is that nearZeroVar function can be used to identify near zero–variance variables and it only identify, how can I remove those variables that were identify, because I have many zero- or near zero- ones, it is not realistic to

[R] Hello all, How can I get corss-validation MSE of SVM in e1071?

as known, svm need tune some parameters like cost,gamma and epsilon to get better performance,but one question appear, how can i monitor the performance . generally speaking ,we chose the cross-validation MSE in the training set, but It seems svm can not return the cross-validation MSE value, we

You can get this using the caret package. There are a few package vignettes that come with the package and a JSS article http://www.jstatsoft.org/v28/i05/paper about the package. Max On Fri, Dec 18, 2009 at 12:26 PM, bbslover dlu...@yeah.net wrote: as known, svm need tune some parameters
