extends CaseControlLikeSampling<I,​D>
    The idea behind this Sampling method is to weight instances depended on the way a pilot estimator p classified them. Instances that p classified right but was unsure contain the most information and are most likely to be chosen. Instances that p is very sure about and Instances that p is quite sure about their actual class and classified them falsely, are medium likely to be chosen. Instances that p is very unsure about their actual class and classified them falsely are not likely to be chosen. Note that any instance still has a base probability to be chosen.
