OSNN: An Online Semisupervised Neural Network for Nonstationary Data Streams.

Learning from data streams that emerge from nonstationary environments has many real-world applications and poses various challenges. A key characteristic of such a task is the varying nature of target functions and data distributions over time (concept drifts). Most existing work relies solely on labeled data to adapt to concept drifts in classification problems.

Efficient Cluster-Based Boosting for Semisupervised Classification.

Semisupervised classification (SSC) consists of using both labeled and unlabeled data to classify unseen instances. Due to the large number of unlabeled data typically available, SSC algorithms must be able to handle large-scale data sets. Recently, various ensemble algorithms have been introduced with improved generalization performance when compared to single classifiers.

Semisupervised classification with cluster regularization.

Semisupervised classification (SSC) learns, from cheap unlabeled data and labeled data, to predict the labels of test instances. In order to make use of the information from unlabeled data, there should be an assumed relationship between the true class structure and the data distribution. One assumption is that data points clustered together are likely to have the same class label.
