| """Parallel grid search for sklearn's GradientBoosting. | |
| This script uses IPython.parallel to run cross-validated | |
| grid search on an IPython cluster. Each cell on the parameter grid | |
| will be evaluated ``K`` times - results are stored in MongoDB. | |
| The procedure tunes the number of trees ``n_estimators`` by averaging | |
