Abstract : The goal of feature selection (FS) in machine learning is to find the best subset of features to create efficient models for a learning task. Different FS methods are then used to assess features relevancy. An efficient feature selection method should be able to select relevant and non-redundant features in order to improve learning performance and training efficiency on large data. However in the case of non-independents features, we saw existing features selection methods inappropriately remove redundancy which leads to performance loss. We propose in this article a new criteria for feature redundancy analysis. Using our proposed criteria, we then design an efficient features redundancy analysis method to eliminate redundant features and optimize the performance of a classifier. We experimentally compare the efficiency and performance of our method against other existing methods which may remove redundant features. The results obtained show that our method is effective in maximizing performance while reducing redundancy.
