TL;DR: Novel feature selection method based on neural estimation of mutual information
Abstract: We describe a novel approach to supervised feature selection based on neural estimation of mutual information between features and targets. Our feature selection filter evaluates subsets of features as an ensemble, instead of considering one feature at a time as most feature selection filters do. This allows us to capture sophisticated relationships between features and targets, and to take such sophisticated relationships into account when selecting relevant features. We give examples of such relationships, and we demonstrate that in this way we are capable of performing an exact selection, whereas other existing methods fail to do so.
