论文摘要
最近的作品揭示了设计损失功能的重要范式,该损失功能与骨总损失不同。单个损失衡量样本上模型的质量,而总损失结合了每个训练样本的个体损失/分数。两者都有一个共同的过程,将一组单个值集合到单个数值值。排名顺序反映了设计损失时个人价值观之间最基本的关系。此外,可以将损失分解成单个术语的合奏的可分解性成为组织损失/得分的重要特性。这项调查对机器学习中的基于等级的可分解损失进行了系统的全面审查。具体而言,我们提供了损失功能的新分类法,遵循总损失和个人损失的观点。我们确定聚合器以形成此类损失,这些损失是集合功能的示例。我们将基于等级的分解损失组织为八类。遵循这些类别,我们回顾有关基于等级的总损失和基于等级的个人损失的文献。我们描述了这些损失的一般公式,并将其与现有的研究主题联系起来。我们还建议未来的研究方向涵盖基于等级的可分解损失的未开发,剩余和新兴问题。
Recent works have revealed an essential paradigm in designing loss functions that differentiate individual losses vs. aggregate losses. The individual loss measures the quality of the model on a sample, while the aggregate loss combines individual losses/scores over each training sample. Both have a common procedure that aggregates a set of individual values to a single numerical value. The ranking order reflects the most fundamental relation among individual values in designing losses. In addition, decomposability, in which a loss can be decomposed into an ensemble of individual terms, becomes a significant property of organizing losses/scores. This survey provides a systematic and comprehensive review of rank-based decomposable losses in machine learning. Specifically, we provide a new taxonomy of loss functions that follows the perspectives of aggregate loss and individual loss. We identify the aggregator to form such losses, which are examples of set functions. We organize the rank-based decomposable losses into eight categories. Following these categories, we review the literature on rank-based aggregate losses and rank-based individual losses. We describe general formulas for these losses and connect them with existing research topics. We also suggest future research directions spanning unexplored, remaining, and emerging issues in rank-based decomposable losses.
