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 well [27]. While these approaches can significantly increase scalability [28], for very large datasets their sequential nature can still be problematic. Web只有满足一致性,我们才可以替换。高老师的这篇文章On the Consistency of AUC Pairwise Optimization就证明了哪些替代损失函数是满足一致性的。 通过替换不同的损失函数,可以得到不同的目标式,从而进行求解。关于怎么求解AUC的文章也有很多,比如说:
Data Removal from an AUC Optimization Model SpringerLink
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 … Web2 de ago. de 2012 · AUC is an important performance measure and many algorithms have been devoted to AUC optimization, mostly by minimizing a surrogate convex loss on a … how many days till 22 october

Web3 de ago. de 2012 · Thus, the consistency of AUC is crucial; however, it has been almost untouched before. In this paper, we provide a sufficient condition for the asymptotic consistency of learning approaches based on surrogate loss functions. Based on this result, we prove that exponential loss and logistic loss are consistent with AUC, but … 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. WebAUC (area under ROC curve) is an important evaluation criterion, which has been popularly used in many learning tasks such as class-imbalance learning, cost-sensitive learning, … high standard shotgun for sale
