 +In multi-class classification problem, the training data and the
 +out-of-sample test data may have different distributions. A method called BCOPS
 +(balanced and conformal optimized prediction sets) constructs a prediction set C(x)
 +as a subset of class labels, possibly empty. It tries to optimize the out-of-sample
 +performance, aiming to include the correct class as often as possible, but also
 +detecting outliers x, for which the method returns no prediction (corresponding to
 +C(x) equal to the empty set).
