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.

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 … WebIn this section, we first propose an AUC optimization method from positive and unlabeled data and then extend it to a semi-supervised AUC optimization method. 3.1 PU-AUC Optimization In PU learning, we do not have negative data while we can use unlabeled data drawn from marginal density p(x) in addition to positive data: X U:= fxU k g n U k=1 ...

An interesting problem is to study AUC consistency on linear function spaces for further work. Gao and Zhou [19] gave a sufficient condition and a necessary condition for AUC consistency based on minimizing pairwise surrogate losses, but it …
WebThe Area under the ROC curve (AUC) is a well-known ranking metric for problems such as imbalanced learning and recommender systems. The vast majority of existing AUC-optimization-based machine learning methods only focus on binary-class cases, while leaving the multiclass cases unconsidered. In this …
