In particular, the number of novel classes is usually assumed to be known in advance, and their labels are sometimes used to tune hyperparameters.

We then give an overview of the different families of approaches, organized by the way they transfer knowledge from the labeled set to the unlabeled set.

In this article we introduce a new model, the HDP-HMM or infinite hidden Markov model, whose performance in trace segmentation is very close to human cognition.
