摘要:

获取大的带注释的数据集对于训练成功的机器学习模型至关重要,并且它通常是实践中的瓶颈。弱监督提供了一种有前途的替代方案,通过使用多个噪声分类生成概率标签来生成没有地面实况注释的标记数据集。这个过程可以扩展到大型数据集,并在医疗保健和电子商务等不同领域展示了最先进的性能。从用户生成的知识库中学习的一个实际问题是,它们的创建需要手工制作它们的人的创造力,远见和领域专业知识,这是一个繁琐和主观的过程。我们开发了第一个框架,互动式弱监督的方法,提出了启发式和学习用户反馈给每个建议的启发式。我们的实验表明,只需要少量的反馈迭代训练模型,实现高度竞争力的测试集性能,而无需访问地面真实训练标签。我们进行了用户研究,结果表明用户能够有效地提供启发式反馈,并且测试集结果跟踪模拟预言机的性能。

英文摘要:

Obtaining large annotated datasets is critical for training successful machine learning models and it is often a bottleneck in practice. Weak supervision offers a promising alternative for producing labeled datasets without ground truth annotations by generating probabilistic labels using multiple noisy heuristics. This process can scale to large datasets and has demonstrated state of the art performance in diverse domains such as healthcare and e-commerce. One practical issue with learning from user-generated heuristics is that their creation requires creativity, foresight, and domain expertise from those who hand-craft them, a process which can be tedious and subjective. We develop the first framework for interactive weak supervision in which a method proposes heuristics and learns from user feedback given on each proposed heuristic. Our experiments demonstrate that only a small number of feedback iterations are needed to train models that achieve highly competitive test set performance without access to ground truth training labels. We conduct user studies, which show that users are able to effectively provide feedback on heuristics and that test set results track the performance of simulated oracles.
