摘要:

多标签排名将实例映射到来自多个可能类别的预测标签的排名集合。多标签学习问题的排名方法因其在多标签分类中的成功而受到关注,其中一种著名的方法是成对标签排名。然而,大多数现有的方法假设,只有部分信息的偏好关系是已知的,这是推断从分区的标签分为一个积极的和消极的集合,然后对待标签具有同等的重要性。在本文中,我们专注于独特的挑战,排名时,真正的标签集的顺序提供。我们提出了一种新的专用损失函数,通过对错误排序的对进行惩罚来优化模型,并利用输入中的排序信息。我们的方法在合成和真实世界排名的数据集上都实现了最佳的性能指标,并在标签的整体排名上有所改进。我们的实验结果表明,我们的方法是可推广到各种多标签分类和排名任务,同时揭示了一个校准到一定的排名排序。

英文摘要:

Multi-label ranking maps instances to a ranked set of predicted labels from multiple possible classes. The ranking approach for multi-label learning problems received attention for its success in multi-label classification, with one of the well-known approaches being pairwise label ranking. However, most existing methods assume that only partial information about the preference relation is known, which is inferred from the partition of labels into a positive and negative set, then treat labels with equal importance. In this paper, we focus on the unique challenge of ranking when the order of the true label set is provided. We propose a novel dedicated loss function to optimize models by incorporating penalties for incorrectly ranked pairs, and make use of the ranking information present in the input. Our method achieves the best reported performance measures on both synthetic and real world ranked datasets and shows improvements on overall ranking of labels. Our experimental results demonstrate that our approach is generalizable to a variety of multi-label classification and ranking tasks, while revealing a calibration towards a certain ranking ordering.
