Abstract
The problem of combining multiple feature rankings into a more robust ranking is investigated. A general framework for ensemble feature ranking is proposed, alongside four instantiations of this framework using different ranking aggregation methods. An empirical evaluation using 39 UCI datasets, three different learning algorithms and three different performance measures enable us to reach a compelling conclusion: ensemble feature ranking do improve the quality of feature rankings. Furthermore, one of the proposed methods was able to achieve results statistically significantly better than the others.
