周志华团队：深度森林挑战多标签学习，9大数据集超越传统方法

Web通过将多标签学习问题转化为每个标签独立的二元分类问题，即Binary Relevance 算法[Tsoumakas and Katakis, 2007]是一种简单的方法，已在实践中得到广泛应用。虽然它的目标是充分利用传统的高性能单标签分类器，但是当标签空间较大时，会导致较高的计算成本。 Web3.1.1 Binary Relevance(first-order) Binary Relevance的核心思想是将多标签分类问题进行分解，将其转换为q个二元分类问题，其中每个二元分类器对应一个待预测的标签。例如，让我们考虑如下所示的一个案例。我们有这样的数据集，X是独立的特征，Y是目标变量。 优点：
