#2237: Addressed part of the comments above:

  • Methods are similar to the ones from SupportVectorMachineUtil
  • Cleaned up sample scripts
  • Elapsed time is shown in seconds
  • Included demo problem
  • Added stratified crossvalidation (shuffling is turned off by default)
  • Added different GridSearch methods with/without crossvalidation.
  • Fixed bug in fold generation when the number of folds is larger than the number of values
13:30 Changeset [11361] by bburlacu

#2234: Added the option to shuffle the crossvalidation folds (this option is on by default since libsvm does it too). Implemented stratified fold generation for classification data (ensures similar label distribution in each fold).
