Chris Lin iirc has advocated partitioning the examples then concatenation the
individual classifiers.
You could do that and then do a second pass of learning: find the 1% of
examples that are the hardest for the ensemble and learn over them.
Regardless, it will be adhoc unless you use an out of
I think @glouppe is likely to contribute some evolution for the ensembles
of trees models once he gets back from ECML 2012 where he has a paper on

any particular problem. However as soon as I began using a much bigger
dataset (with the exact same code), I got this threading error:
