Parallel grid search for sklearn Gradient Boosting
"""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
the staged scores of the GBRT model averaged over all K folds.
You need an IPython ipcluster to connect to - for local use simply
