摘要:

半监督学习已经成为一种流行的框架,用于提高建模精度,同时控制标记成本。基于扩展的随机复合似然,我们量化的渐进精度的生成半监督学习。在这样做的过程中,我们通过提供一个替代框架来衡量与不同标签政策相关的价值,并解决标记多少数据以及以何种方式标记的基本问题,从而补充了无分布分析。我们展示了我们的方法与模拟研究和现实世界的实验,使用朴素贝叶斯文本分类和MRF和CRF的结构化预测在NLP。

英文摘要:

Semisupervised learning has emerged as a popular framework for improving modeling accuracy while controlling labeling cost. Based on an extension of stochastic composite likelihood we quantify the asymptotic accuracy of generative semi-supervised learning. In doing so, we complement distribution-free analysis by providing an alternative framework to measure the value associated with different labeling policies and resolve the fundamental question of how much data to label and in what manner. We demonstrate our approach with both simulation studies and real world experiments using naive Bayes for text classification and MRFs and CRFs for structured prediction in NLP.
