Binary relevance多标签分类
WebApr 8, 2024 · ----- • Binary Relevance方式的优点如下： • 实现方式简单，容易理解； • 当y值之间不存在相关的依赖关系的时候，模型的效果不错。 • 缺点如下： • 如果y直接存在相互的依赖关系，那么最终构建的模型的泛化能力比较 弱； • 需要构建q个二分类器，q为待 ... 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：
