[pymvpa] Parameter Search SVM

[Andreas Mueller]

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

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.
