摘要:

随着使用机器学习算法的应用程序数量的增加,对用于训练此类算法的标记数据的需求加剧。获取标签通常涉及雇用人类进行注释,这直接转化为培训和工作成本。众包平台使标记更便宜,更快,但它们仍然涉及巨大的成本,特别是对于待标记的潜在候选数据集很大的情况。在本文中,我们描述了一种方法和一个原型系统,旨在解决这一挑战,在工业环境中的Web规模的问题。我们讨论了如何有效地选择用于机器学习算法训练的数据以降低成本的想法。通过仔细选择要标记的实例,我们展示了以降低成本实现良好性能的结果。我们提出的算法是作为管理和生成训练数据集的框架的一部分提出的,该框架包括人类计算元素等组件。

英文摘要:

As the number of applications that use machine learning algorithms increases, the need for labeled data useful for training such algorithms intensifies. Getting labels typically involves employing humans to do the annotation, which directly translates to training and working costs. Crowdsourcing platforms have made labeling cheaper and faster, but they still involve significant costs, especially for the cases where the potential set of candidate data to be labeled is large. In this paper we describe a methodology and a prototype system aiming at addressing this challenge for Web-scale problems in an industrial setting. We discuss ideas on how to efficiently select the data to use for training of machine learning algorithms in an attempt to reduce cost. We show results achieving good performance with reduced cost by carefully selecting which instances to label. Our proposed algorithm is presented as part of a framework for managing and generating training datasets, which includes, among other components, a human computation element.
