Information Theoretic Combination of Classifiers with Application to AdaBoost

摘要

Combining several classifiers has proved to be an efficient machine learning technique. We propose a new measure of the goodness of an ensemble of classifiers in an information theoretic framework. It measures a trade-off between diversty and individual classifier accuracy. This technique can be directly used for the selection of an ensemble in a pool of classifiers. We also propose a variant of AdaBoost for directly training the classifiers by taking into account this new information theoretic measure.
