abstract = "One-class classification naturally only provides one
class of exemplars on which to construct the
classification model. In this work, multi-objective
genetic programming (GP) allows the one-class learning
problem to be decomposed by multiple GP classifiers,
each attempting to identify only a subset of the target
data to classify. In order for GP to identify
appropriate subsets of the one-class data, artificial
outclass data is generated in and around the provided
inclass data. A local Gaussian wrapper is employed
where this reinforces a novelty detection as opposed to
a discrimination approach to classification.
Furthermore, a hierarchical subset selection strategy
is used to deal with the necessarily large number of
generated outclass exemplars. The proposed approach is
demonstrated on three one-class classification datasets
and was found to be competitive with a one-class SVM
classifier and a binary SVM classifier.",
