中文摘要
主流机器学习工具依赖于人类注释训练数据的可用性。如今,在所谓的大数据时代,机器学习的应用程序可以获得非常大量的未注释(也称为未标记)数据。因此,人们对设计机器学习工具非常感兴趣,这些工具可以利用如此大量的原始、未注释的数据来减少对学习过程的人为干预。最近出现的各种机器学习范式都解决了这个问题。这些范式包括聚类、主动学习、半监督学习、领域适应和迁移学习,以及向`弱教师‘学习’(如通过众包获得的监督)。
英文摘要
Mainstream machine learning tools depend on the availability of human annotated training data. Nowaday, in what is called the ``big data" era, applications of machine learning have access to very large amounts of un-annotated (a.k.a. unlabeled) data. Consequently, there is vast interest in designing machine learning tools that can utilize such big pools of raw, unannotated data to reduce the need for human intervention in the learning process. Various recently arising machine learning paradigms address this issue. These include Clustering, Active Learning, Semi-Supervised Learning, Domain Adaptation and Transfer Learning, as well as Learning from ``Weak Teachers" (like supervision obtained via crowdsourcing).
