Since kNN classifiers are sensitive to outliers and noise contained
in the training data set, many approaches have been proposed
to edit the training data so that the performance of the classifiers can
be improved. In this paper, through detaching the two schemes adopted
by the Depuration algorithm, two new editing approaches are derived.
Moreover, this paper proposes to use neural network ensemble to edit
the training data for kNN classifiers. Experiments show that such an
approach is better than the approaches derived from Depuration, while
these approaches are better than or comparable to Depuration.
