Decision trees are intelligible, but do they perform well enough that you should use them? Have SVMs replaced neural nets, or are neural nets still best for regression, and SVMs best for classificatio

Best Ensembles are Big & Ugly!427:21:09
Best Ensembles are Big & Slow!444:02:05
Can’t we make the ensembles smaller, faster, and easier to use by eliminating some base-level models?473:38:41
