摘要:
多标签排序是机器学习中的一项核心任务。然而,在具有相关度分数反馈的多标签排序设置中,最根本的可学习性问题仍未得到解答。本文刻画了在批处理和在线两种设置下,针对一大类排序损失的多标签排序问题的可学习性。在此过程中,我们基于可学习性给出了两类排序损失的等价类,这些等价类涵盖了实践中使用的大多数(即便不是全部)损失。
英文摘要:
Multilabel ranking is a central task in machine learning. However, the most fundamental question of learnability in a multilabel ranking setting with relevance-score feedback remains unanswered. In this work, we characterize the learnability of multilabel ranking problems in both batch and online settings for a large family of ranking losses. Along the way, we give two equivalence classes of ranking losses based on learnability that capture most, if not all, losses used in practice.
