Random search vs. GridSearchCV

Question

I want to use random search algorithm instead of grid search with scikit-learn. But I can only find GridSearchCV estimator in documentation. Is it possible to use random search instead of grid search in scikit-learn?

Answer 1

Random search was added to the dev version 5 days ago, so yes you can, if you're willing to use the bleeding edge version. Otherwise, either wait for the next (0.14) release, or consider using hyperopt.
