Hi Julian.
Since I am not an expert on pymvpa I will let the others answer your precise question.

But I have a script building upon pymvpa and pp to do cross validation for parameter search
on multiple cores and over ssh.

It's only a couple of lines and very easy to use.
Let me know if you're interested.

Cheers,
Andy

Hello,

i'm currently working on a project where i have to select hyperparameters for 
the libSVM implementation which generate a model which fits a dataset best 
(compared to other hyperparameters). Is there any implementation available in 
pymvpa accomplishes this job? I found Modelselector but as i unterstood the 
logic it needs the classifier/model to have a method called 
compute_log_marginal_likelihood which the SVM clfers seem to lag.
