原始语种摘要: Abstract(#br)Abstaining classifiers refrain from uncertain classifications to decrease errors and have been widely applied in critical fields. There are two types of abstaining classifiers: Chow’s rule-based and receiver operating characteristic (ROC)-based. Chow’s rule is obtained by minimizing the overall error rate given a reject rate. Therefore, Chow’s rule-based classifiers do not consider the difference between false positives and false negatives. ROC-based abstaining classifiers minimize cost functions; therefore, costs of classification and rejection need to set during the training stage. However, in real-world applications, misclassification costs of different classes are usually unequal. Furthermore, costs of classification and rejection are not easy to obtain and they may vary...
