Detailed Description

Class splitting a set into training set and validation set in a crossvalidation manner.

This is done in a balanced way, meaning the proportions between the classes in the trainingset is close to the proportions in the whole dataset. In the first k rounds each sample is returned k-1 times, for next round the samples are shuffled and... In total there are N partitions, in other words, each sample is in validation roughly N/k
