On optimal reject rules and ROC curves
In this paper we make the connection between two approaches for supervised classification with a rejection option. The first approach is due to Tortorella and is based on ROC curves and the second is a generalisation of Chow s optimal rule. 2004 Elsevier B.V. All rights reserved.
متن کاملROC curves and the test
In this paper we review the Receiver Operating Characteristic ROC curve and the test statistic in relation to the analysis of a confusion matrix We then show how these two methods are related and propose an extension to the ROC curve so that it shows contours of values These contours can be used to provide further insight into the appropriate setting of the decision threshold for a particular a...
متن کاملResampling ROC curves
Receiver operating characteristic (ROC) curves are very popular for evaluating a diagnostic test or score performances in various decision making applications: medicine, marketing, credit scoring etc. The ROC curve provides a concise graphical representation of the trade off between sensitivity and specificity. We will focus here on supervised classification into two groups. Error rate estimati...
متن کاملROC Curves for Steganalysts
There are different approaches in the literature for the assessment of steganographic algorithms and steganalytic attacks. In the early papers it was considered sufficient to show the existence of an effect for one or a few examples only. The more the area of steganography evolved, the more diverse became the goals and the harder to measure the improvements. Many branches of science are facing ...
