21.1 Introduction
Supervised machine learning techniques have already been widely studied and applied to various real-world applications. However, most existing supervised algorithms work well only under a common assumption: the training and test data are represented by the same features and drawn from the same distribution. Furthermore, the performance of these algorithms heavily rely on collecting high quality and sufficient labeled training data to train a statistical or computational model to make predictions on the future data [57, 86, 132]. However, in many real-world scenarios, labeled training data are in short supply ...
