Dynamic ensemble selection for multi -class classification with one-class classifiers

摘要

In this paper we deal with the problem of addressing multi-class problems with decomposition strategies. Based on the divide-and-conquer principle, a multi-class problem is divided into a number of easier to solve sub-problems. In order to do so, binary decomposition is considered to be the most popular approach. However, when using this strategy we may deal with the problem of non-competent classifiers. Otherwise, recent studies highlighted the potential usefulness of one-class classifiers for this task. Despite not using all the available knowledge, one-class classifiers have several desirable properties that may benefit the decomposition task.
