In practical … Witryna16 gru 2008 · Exploratory Undersampling for Class-Imbalance Learning. Abstract: Undersampling is a popular method in dealing with class-imbalance problems, which uses only a subset of the majority class and thus is very efficient. The main deficiency is that many majority class examples are ignored. We propose two algorithms to …
