Abstract

Feature selection consists on selecting relevant features in order to focus the learning search. A simple and efficient setting for feature selection is to rank the features with respect to their relevance. When several rankers are applied to the same data set, their outputs are often different. Combining preference lists from those individual rankers into a single better ranking is known as rank aggregation. In this study, we develop a method to combine a set of ordered lists of feature based on an optimization function and genetic algorithm. We compare the performance of the proposed approach to that of well-known methods. Experiments show that our algorithm improves the prediction accuracy compared to single feature selection algorithms or traditional rank aggregation techniques.
