....the training set can be balanced by duplicating the training examples of the minority class or by creating new examples by corrupting existing ones with artificial noise (DeRouin et al. 1991) Solberg and Solberg (1996) do both: positives are duplicated and negatives are randomly sampled. Honda et al. 1997) reduce the imbalance by doing classification in two stages. In the first stage, the negatives most similar to the positives are included in the positive class. The second stage distinguishes these negatives from the true positives. This can be seen as a special case of multitask learning ....
