TL;DR
本文提出了利用排名约束估计与低维标签嵌入之间的对应关系来发现一种新的、快速的标签嵌入算法，并展示了其在多类问题和多标签问题中的应用，最终实现了指数级的运行时间优化，其中在两个大规模公共数据集上的结果优于现有技术。
Abstract
Many modern multiclass and
multilabel problems
are characterized by increasingly large output spaces. For these problems,
label embeddings
have been shown to be a useful primitive that can improve computational a
