Cost sensitive search
WebA more general setting is cost-sensitive classification where the costs caused by different kinds of errors are not assumed to be equal and the objective is to minimize the expected costs. In case of class-dependent costs the costs depend on the true and predicted class label. The costs c ( k, l) for predicting class k if the true label is l ... WebJun 18, 2010 · Cost-sensitive subspace learning for face recognition. Abstract: Conventional subspace learning-based face recognition aims to attain low recognition errors and assumes same loss from all misclassifications. In many real-world face recognition applications, however, this assumption may not hold as different misclassifications could …
