Dynamic classifier integration method

Abstract

The diversity of application domains of pattern recognition makes it difficult to find a highly reliable classification algorithm for sufficiently interesting tasks. In this paper we propose a new combining method, which harness the local confidence of each classifier in the combining process. Our method is at the confluence of two main streams of combining multiple classifiers: classifier fusion and classifier selection. This method learns the local confidence of each classifier using training data and if an unknown data is given, the learned knowledge is used to evaluate the outputs of individual classifiers. An empirical evaluation using five real data sets has shown that this method achieves a promising performance and outperforms the best single classifiers and other known combining methods we tried. © Springer-Verlag Berlin Heidelberg 2005.
