Dear R-community,
I was using SVM regression (svm {e1071}) for predictions of single
soil properties of a huge data set (3000 samples). There are for the
eps-regression using the radial basis kernel three optimization
parameters needed.
To make things easier (using only two optimization parameters and not
loosing performance) I wanted to use LS SVM regression
(lssvm{kernlab}). But it looks to me that it is not yet implemented.
At least I got error messages, which I could not find a solution for
(Error in if (n !_dim(y)[1] stop ("Labels y and data x dont match").
Otherwise I could not find another LSSVM regression implementation in
R, or is there?
Regards,
Thomas
