In this paper, a strictly concave approximation of MOCU – referred to as “Soft MOCU” – is proposed, which can be used to define an acquisition function for Bayesian active learning with a theoretical convergence guarantee. This study shows that the Soft MOCU based Bayesian active learning outperforms other existing methods, with the important additional benefit of theoretical guarantee of convergence to the optimal classifier.
