摘要:

在实践中存在许多为机器学习分类任务注释数据集的方法,这些方法超出了通常的类标签。这些是令人感兴趣的,因为它们可以简化或促进注释的收集,同时不会极大地影响所得到的机器学习模型。其中许多属于弱标签或注释的保护范围。然而,不同的替代品之间的关系并不总是很清楚。在本文中,我们提出了一个弱监督设置分类框架,目的是:(1)帮助数据集所有者或注释者在规定注释过程时浏览弱监督中的可用选项,以及(2)向机器学习从业者描述数据集的现有注释,以便我们允许他们理解学习过程的含义。为此,我们确定的关键因素,消除薄弱的监督,并设计了一系列的尺寸,分类大多数现有的方法。我们将展示如何在文献中常见的设置适合的框架内,并讨论其在实践中可能的用途。

英文摘要:

Many ways of annotating a dataset for machine learning classification tasks that go beyond the usual class labels exist in practice. These are of interest as they can simplify or facilitate the collection of annotations, while not greatly affecting the resulting machine learning model. Many of these fall under the umbrella term of weak labels or annotations. However, it is not always clear how different alternatives are related. In this paper we propose a framework for categorising weak supervision settings with the aim of: (1) helping the dataset owner or annotator navigate through the available options within weak supervision when prescribing an annotation process, and (2) describing existing annotations for a dataset to machine learning practitioners so that we allow them to understand the implications for the learning process. To this end, we identify the key elements that characterise weak supervision and devise a series of dimensions that categorise most of the existing approaches. We show how common settings in the literature fit within the framework and discuss its possible uses in practice.
