Max-Margin Stacking and Sparse Regularization for Linear Classifier Combination and Selection.
Abstract
The main principle of stacked generalization (or Stacking) is using a
second-level generalizer to combine the outputs of base classifiers in an
ensemble. In this paper, we investigate different combination types under the
stacking framework; namely weighted sum (WS), class-dependent weighted sum
(CWS) and linear stacked generalization (LSG). For learning the weights, we
propose using regularized empirical risk minimization with the hinge loss. In
addition, we propose using group sparsity for regularization to facilitate
classifier selection. We performed experiments using two different ensemble
setups with differing diversities on 8 real-world datasets. Results show the
power of regularized learning with the hinge loss function. Using sparse
regularization, we are able to reduce the number of selected classifiers of the
diverse ensemble without sacrificing accuracy. With the non-diverse ensembles,
we even gain accuracy on average by using sparse regularization.
