Topic modeling is an unsupervised machine learning method that analyzes text data and determines cluster words for a set of documents. Unsupervised learning often experiences the curse of dimensionality, however subspace modeling can overcome this problem. Semi-supervised learning combines aspects of supervised learning, where all of the training data is labeled, and unsupervised learning, where true labels are unknown. In unsupervised learning, an algorithm segregates the data in a data set in which the data is unlabeled based on some hidden features in the data.
