It starts with a labeled seed set and a larger unlabeled pool, trains a model, selects queries, obtains labels and repeats. The aim is to use annotation effort effectively. It does not guarantee fewer labels for every task, and it differs from generating synthetic queries or automatically assigning pseudo-labels.
