Finding linear classifiers that maximize AUC scores is important in ranking research. This is naturally formulated as a 1-norm hard/soft margin optimization problem over pn pairs of p positive and n negative instances. However, directly solving the optimization problems is impractical since the problem size (pn) is quadratically larger than the given sample size (p + n). In this paper, we give ...

In a randomised controlled trial (RCT) we are usually trying to answer the question of which treatment is best. Sometimes, though, may be considering that do not believe will perform better than an existing option but has other benefits: it could cheaper, easier deliver or more acceptable patients. For example, need for urodynamic testing compared with simple office evaluation before stress inc...
