关于半监督学习的综述，包括了所有主要方法，比如cotraining算法等等，可以对该领域有一个全面的认识

希腊希尔维亚的模式识别的源码。可以用来学习模式识别。-Source code in Matlab for Pattern Recogintion from xi la

半监督学习co-training 回归算法的java代码实现。-COREG is a co-training style semi-supervised regression algorithm, which employs two kNN regressors using different distance metrics to select the most confidently labeled unlabeled examples for each other.

用java实现了co-training，用于少量标注数据来获取大量的标注数据，也在于解决数据不均衡问题(This is an algorithm for aspect-based sentiment analysis using co-training, a semi-supervised machine learning algorithm that partitions the machine learning features into two sufficient and uncorre
