- Aggregated classification trees have gained recognition due to improved stability, and frequently reduced bias. However, the adaptation of this approach to the k nearest neighbors method (kNN), faces some difficulties: the relatively high stability of these classifiers, and an increase of misclassifications when the variables without discrimination power are present in the training set. In this paper we propose aggregated kNN classifier with feature selection. Its classification accuracy has been verified on the real data with added irrelevant variables.
