Least-square support vector machines regression!
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

error installing/compiling kernlab
Hi everybody, I''m using R on a 64-bit Ubuntu 9.04 (Jaunty). I prefer to install R packages from source, even if they are available in Synaptic. The problem is that I can''t install/compile kernlab. Everything works fine until it gets to the lazy loading part: ** preparing package for lazy loading Creating a new generic function for "terms" in "kernlab"

cross validation in rvm not working? (kernlab package)
Hi, according to ?rvm the relevance vector machine function as implemented in the kernlab-package has an argument 'cross' with which you can perform k-fold cross validation. However, when I try to add a 10-fold cross validation I get the following error message: Error in match.arg(type, c("C-svc", "nu-svc", "kbb-svc", "spoc-svc",

Kernlab: multidimensional targets in rvm(), ksvm(), gausspr()
Hi there, I'm trying to do a regression experiment on a multidimensional dataset where both x and y in the model are multidimensional vectors. I'm using R version 2.9.2, updated packages, on a Linux box. I've tried gausspr(), ksvm() and rvm(), and the models are computed fine, but I'm always getting the same error message when I try to use predict(): "Error in

svm of e1071 package
Hello List, I am having a great trouble using svm function in e1071 package. I have 4gb of data that i want to use to train svm. I am using Amazon cloud, my Amazon Machine Image(AMI) has 34.2 GB of memory. my R process was killed several times when i tried to use 4GB of data for svm. Now I am using a subset of that data and it is only 1.4 GB. i remove all unnecessary objects before calling

Data format for KSVM
Hi, I have a process using svm from the e1071 library. it works. I want to try using the KSVM library instead. The same data used wiht e1071 gives me an error with KSVM. My data is a data.frame. sample code: svm_formula <- formula(y ~ a + B + C) svm_model <- ksvm(formula, data=train_data, type="C-svc", kernel="rbfdot", C=1) I get the following error:

BUG with LSSVM in R:
Hello, I have noticed a bug with LSSVM implementation in R. It could be a bug with the LSSVM itself that causes this problem. I thought I should post this message to see if anyone else is familiar with this problem and explain why the result is different for odd and even number of cases. Once the hyperplane is found using LSSVM, the prediction results vary when you predict odd or even number of

Problem using rvm in bash script
I am using rvm installed on Ubuntu 10.04 as recommended in the rvm docs (including changes to .bashrc) and all is working well with several versions of Rails, and Ruby 1.8.7 and 1.9.2. If I run rvm use 1.9.2 it says Using /home/colinl/.rvm/gems/ruby-1.9.2-p0 and if I run rvm info It shows exactly what I would expect for 1.9.2 and I can start the rails server and all is well. The problem arises if

a first opinion on rattle
Graham   I have installed rattle and is pretty intuitive and friendly. However, I miss some features of the original packages which cannot be invoked from rattle. For example, 'randomForest' package is used but random forests cannot be used in one of  -in my opinion- most powerful aspects like regression. The same about SVM . I would also say include RVM which the scientific literature

RVM on a Macbook
I have a Macbook with Snow Leopard and Macports. I have successfully run the script displayed below the heading "The following script will boostrap git + RVM..." on the page: http://rvm.beginrescueend.com/rvm/install/ However I can find no .bash_profile or .bashrc on my machine. The closest existing files are .profile in my root, .bash_login in my root, and setup.bash.in in a subfolder

Should be obvious, but how do I even know what versions of ruby are available for rvm to use with rvm install?
I''m getting back to learning rails and at one point I used rvm to install some rubies. Now I''m playing dumb and want to install the latest ruby version - latest beta. How in the world do I found out the name of it? I''d think it would be named somewhere here http://www.ruby-lang.org/en/downloads/ and then I could just do rvm install ruby-XYZ. I don''t get where I
