Good Semi-supervised Learning That Requires a Bad GAN 恢复博客更新,最近没那么忙了,记录一下学习. Intro 本文是一篇稍微偏理论的半监督学习的文章,通过证明一个能够生成非目标分布的.低样本密度的样本的生成器,对半监督学习的效果有很大的提升,这样的生成器作者称之为Complement Generator,而提升的原因是生成的bad样本填充了特征空间的低密度区域,从而使得分类的分类面在低密度区域,从而避免了分类面穿过流形的情况,因而能够提升分…
by 南大周志华 摘要 监督学习技术通过学习大量训练数据来构建预测模型,其中每个训练样本都有其对应的真值输出.尽管现有的技术已经取得了巨大的成功,但值得注意的是,由于数据标注过程的高成本,很多任务很难获得如全部真值标签这样的强监督信息.因此,能够使用弱监督的机器学习技术是可取的.本文综述了弱监督学习的一些研究进展,主要关注三种弱监督类型:不完全监督,即只有一部分样本有标签:不确切监督,即训练样本只有粗粒度的标签:以及不准确监督,即给定的标签不一定总是真值. 关键词:机器学习,弱监督学习,监督学习…
