We introduce the idea of utilizing ensembles of Kernel Minimum Enclosing Balls to detect novel datapoints. To this end, we propose a novelty scoring methodology that is based on combining the outcomes of the corresponding characteristic functions of the fitted balls. We empirically evaluate our model by presenting experiments on synthetic as well as real world datasets.
