In this paper, we propose an active learning framework for subspace clustering that sequentially queries informative points and updates the subspace model.

Associating distinct groups of objects (clusters) with contiguous regions of high probability density (high-density clusters), is central to many statistical and machine learning approaches to the classification of unlabelled data.
