Reduced ensemble size stacking [ensemble learning]
Niall Rooney, David W. Patterson, Chris Nugent · 2005
We investigate an algorithmic extension to the technique of stacked regression that prunes the size of a homogeneous ensemble set based on a consideration of the accuracy and diversity of the set members. We show that the pruned ensemble set is as accurate on average over the data-sets tested as the nonpruned version, which provides benefits in terms of its application efficiency and reduced complexity of the ensemble.
