  abstract =     "Machine learning algorithms can suffer a performance
                 bias when data sets are unbalanced. This paper develops
                 a multi-objective genetic programming approach to
                 evolving accurate and diverse ensembles of
                 non-dominated solutions where members vote on class
                 membership. We explore why the ensembles can also be
                 vulnerable to the learning bias using a range of
                 unbalanced data sets. Based on the notion that smaller
                 ensembles can be better than larger ensembles, we
                 develop a new evolutionary-based pruning method to find
                 groups of highly-cooperative individuals that can
                 improve accuracy on the important minority class.",
