"Leave One Out Cross Validation on SVM"

moudar981

Hi all,
Applying Leave One Out Cross Validation is expensive, but there is very efficient way of applying it on SVM (as it can be applied only on the support vectors), is using this feature possible in Rapidminer?

best regards

Hi,

please explain how this could possibly work: The support vectors are determined on the set of examples during training phase each time the model is trained. On LOOCV this is exactly n times if we have n examples. How could you leave out examples if you don't even have a model to determine if they are Support Vectors or not?
