Been using pymvpa for a few months now and really enjoying it - thanks
for all the good work!
I was curious if it would be possible/useful to switch out the libsvm
backend to the dense version mentioned here:
http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/#1. They claim
approximately 40% increase in speed (though for much larger data sets
than normal for mri), and since all fmri data is dense, it seems a
natural move to me. Has anyone experimented with this? Or is a similar
improvement already included in the pymvpa libsvm wrapper? Or do you
think the performance increase would be negligible?
