论文摘要
ROC曲线下的区域（又称AUC）是评估分类器不平衡数据的性能的选择。 AUC最大化是指通过直接最大化其AUC分数来学习预测模型的学习范式。它已被研究了二十年来，其历史可以追溯到90年代后期，从那时起，大量工作就一直致力于AUC最大化。最近，对大数据和深度学习的深度最大化的随机AUC最大化受到了越来越多的关注，并对解决现实世界中的问题产生了巨大的影响。但是，据我们所知，没有对AUC最大化的相关作品进行全面调查。本文旨在通过回顾过去二十年来审查文献来解决差距。我们不仅给出了文献的全面看法，而且还提供了从配方到算法和理论保证的不同论文的详细解释和比较。我们还确定并讨论了深度AUC最大化的剩余和新兴问题，并就未来工作的主题提供建议。
Area under the ROC curve, a.k.a. AUC, is a measure of choice for assessing the performance of a classifier for imbalanced data. AUC maximization refers to a learning paradigm that learns a predictive model by directly maximizing its AUC score. It has been studied for more than two decades dating back to late 90s and a huge amount of work has been devoted to AUC maximization since then. Recently, stochastic AUC maximization for big data and deep AUC maximization for deep learning have received increasing attention and yielded dramatic impact for solving real-world problems. However, to the best our knowledge there is no comprehensive survey of related works for AUC maximization. This paper aims to address the gap by reviewing the literature in the past two decades. We not only give a holistic view of the literature but also present detailed explanations and comparisons of different papers from formulations to algorithms and theoretical guarantees. We also identify and discuss remaining and emerging issues for deep AUC maximization, and provide suggestions on topics for future work.
