A dynamic integration algorithm for an ensemble of classifiers

subject

description

Numerous data mining methods have recently been developed, and there is often a need to select the most appropriate data mining method or methods. The method selection can be done statically or dynamically. Dynamic selection takes into account characteristics of a new instance and usually results in higher classification accuracy. We discuss a dynamic integration algorithm for an ensemble of classifiers. Our algorithm is a new variation of the stacked generalization method and is based on the basic assumption that each basic classifier is best inside certain subareas of the application domain. The algorithm includes two main phases: a learning phase, which collects information about the quality of classifications made by the basic classifiers into a performance matrix, and an application phase, which predicts the goodness of classification for a new instance produced by the basic classifiers using the performance matrix. In this paper we present also experiments made on three machine learning data sets, which show promising results.
