python - Randomized stratified k-fold cross-validation in scikit-learn? -

-

is there built-in way scikit-learn perform shuffled stratified k-fold cross-validation? 1 of common cv methods, , surprised couldn't find built-in method this.

i saw cross_validation.kfold() has shuffling flag, not stratified. unfortunately cross_validation.stratifiedkfold() not have such option, , cross_validation.stratifiedshufflesplit() not produce disjoint folds.

am missing something? planned?

(obviously can implement myself)

the shuffling flag cross_validation.stratifiedkfold has been introduced in current version 0.15:

http://scikit-learn.org/0.15/modules/generated/sklearn.cross_validation.stratifiedkfold.html

this can found in changelog:

shuffle option cross_validation.stratifiedkfold. jeffrey blackburne.
