摘要: In this paper, we perform an empirical study of the impact noise on cost-sensitive (CS) learning, through observations how a CS learner reacts to mislabeled training examples in terms misclassification cost and classification accuracy. Our results theoretical analysis indicate that can raise serious concerns for classification, especially when misclassifying some classes becomes extremely expensive. Compared general inductive problem handling data cleansing is more crucial, should be carefully investigated ensure success learning.
