The recent trend in software development shows more and more importance on graphical user interface. A graphical user interface is often seen as just indispensable. There are several important components of a graphical user interface, such as, menu, listbox, toolbox, command button, scrollbar, tree navigator, dialog box etc. A command button is a very fundamental element of a graphical user int...

We consider the problem of binary classification where the classifier may abstain instead of classifying each observation. The Bayes decision rule for this setup, known as Chow’s rule, is defined by two thresholds on posterior probabilities. From simple desiderata, namely the consistency and the sparsity of the classifier, we derive the double hinge loss function that focuses on estimating cond...

We consider multi-label classification problems in application scenarios where classifier accu-racy is not satisfactory, but manual annotation is too costly. In single-label problems, a wellknown solution consists of using a reject option, i.e., allowing a classifier to withhold unreliabledecisions, leaving them (and only them) to human operators. We argue that this solution can be<...
