Abstract
Classification over imbalanced datasets is a highly interesting topic given that many real-world classification problems present a concrete class with a much smaller number of patterns than the others. In this work we shall explore the use of large, fully connected and potentially deep MLPs in such problems. We will consider simple MLPs, with ReLU activations, softmax outputs and categorical cross-entropy loss, showing that, when properly regularized, these relatively straightforward MLP models yield state of the art results in terms of the areas under the ROC curve for both two-class problems (the usual focus in imbalanced classification) as well as for multi-class problems.
