- total_n_estimators should be sum(n_estimators) not len(..)
- keyword argument should be after non-keyword argument (call of ``_parallel_build_estimators`` with ``delayed`` on line 365-366.
Add to bagging.Bagging._parallel_build_estimators a total_n_estimators parameter, to improve the (optional) information printed if verbose > 1.
It felt weird to see 6 times in a row "building estimator 1 of 1" without any idea of total number of estimators to build, now it's fixed.
Register OneVsRestRegressor as meta estimator
Rename to a more sensible name
Parallel predict and sparse support
Started MultiOutput documentation
Move code to new file multioutput.py
Continuing the move to new multioutput module
Added sample weight support
Better test for sample weights and actually support weights
Added a new test using weighted vs repeated samples to
test sample weight support. Uncovered that weights
were not actually passed on to underlying estimator.
Comment on multiprocess overheads
Move parallel_helper to utils.fixes
This helper works around a python2 limitation on pickling
instance methods
Example of multi-output regression with gradient boosting
Switch to uniform weighted score and updated example
The example now uses a RF with and without the MultiOutput
meta estimator
Added note for removing `score` method
Addressing comments on MultiOutputRegressor
MultiOutputregressor better test for weighted samples
Fix ups
Use explicit keyword argument for passing sample weights and
fix random_state on train-test split in the example
max_samples='auto' replaces max_samples=256 as the default
setting. Recalculate max_depth based on the actual value
of max_samples after checking range and other constraints
