Co-training is a machine learning algorithm used when there are only small amounts of labeled data and large amounts of unlabeled data. One of its uses is in text mining for search engines . It was introduced by Avrim Blum and Tom Mitchell in 1998.

Query by committee: a variety of models are trained on the current labeled data, and vote on the output for unlabeled data; label those points for which the "committee" disagrees the most Querying from diverse subspaces or partitions : [ 13 ] When the underlying model is a forest of trees, the leaf nodes might represent (overlapping) partitions ...
Manifold regularization can classify data when labeled data (black and white circles) are sparse, by taking advantage of unlabeled data (gray circles). Without many labeled data points, supervised learning algorithms can only learn very simple decision boundaries (top panel). Manifold learning can draw a decision boundary between the natural ...
Labels can be obtained by asking humans to make judgments about a given piece of unlabeled data. [1] Labeled data is significantly more expensive to obtain than the raw unlabeled data. The quality of labeled data directly influences the performance of supervised machine learning models in operation, as these models learn from the provided ...
An autoencoder is a type of artificial neural network used to learn efficient codings of unlabeled data (unsupervised learning).An autoencoder learns two functions: an encoding function that transforms the input data, and a decoding function that recreates the input data from the encoded representation.
