On the consistency of auc optimization

Webis whether the optimization of surrogate losses is consistent with AUC. 1.1. Our Contribution We first introduce the generalized calibration for AUC optimization based on minimizing the pairwise surrogate losses, and find that the generalized cal-ibration is necessary yet insufficient for AUC consistency. For example, hinge Web30 de set. de 2024 · Recently, there is considerable work on developing efficient stochastic optimization algorithms for AUC maximization. However, most of them focus on the least square loss which may be not the best option in practice. The main difficulty for dealing with the general convex loss is the pairwise nonlinearity w.r.t. the sampling distribution …

Webfor AUC optimization the focus is mainly on pairwise loss, as the original loss is also defined this way and consistency results for pairwise surrogate losses are available as … Webwith AUC, as will be shown by Theorem 1 (Section 4). In contrast, loss functions such as hinge loss are proven to be inconsistent with AUC (Gao & Zhou, 2012). As aforementioned, the classical online setting can-not be applied to one-pass AUC optimization because, even if the optimization problem of Eq. (2) has a closed

WebAUC optimization on graph data, which is ubiquitous and important, is seldom studied. Different from regular data, AUC optimization on graphs suffers from not only the class imbalance but also topology imbalance. To solve the complicated imbalance problem, we propose a unified topology-aware AUC optimization framework. Webranking of the data through empirical AUC maximization. The consistency of the test is proved to hold, as soon as the learning procedure is consistent in the AUC sense and its capacity to detect ”small” deviations from the homogeneity assumption is illustrated by a simulation example. The rest of the paper is organized as follows.
