Hello guys,
I have a data set with 10 features and 2 classes. How can I partition it so that I can obtain training set and test set ? Are there any specific algorithms for doing this?
Thanks

Let me share what I've found searching on the net. There are some methods specifically cross validation used for this. These are implemented in the Matlab with the names: crossvar.
If you have any other method please post.
