public class NFoldCrossvalidatedSignalArrays

extends ncsa.d2k.core.modules.DataPrepModule

A module that collects input Signal arrays until a null input is received, splits each into N groups, creates one array containing all but one of the groups from all of the arrays, which is kept to be used as a test set. This process is repeated until each group has been part of the test set.
