[pymvpa] retraining

[Scott Gorlin]

Hi guys,

What's the latest thoughts on precalculated/retrainable classifiers?  
I.e., it could greatly speed up cross-validated model selection... it 
looks like libsvm's precomputed kernel isn't implemented though, is this 
due to a wrapper limitation?  Or are people generally using other 
classifiers which have clf.retrain() implemented?

If I were to implement this, any tips on where to begin?
