These ensemble methods include resampling-based, e.g., under/over-sampling, and reweighting-based ones, e.g., cost-sensitive learning.
Webon cost sensitive learning: assigning a high cost to misclassification of the minority class, and trying to minimize the overall cost. Domingos (1999) and Pazzani et al. (1994) are among these. The other approach is to use a sampling technique: Either down-sampling the majority class or over-sampling the minority class, or both.
