Abstract:

We present a plug-in method for estimating the cluster tree of a density. The method takes advantage of the ability to compute exactly the cluster tree of a piecewise constant density estimate. We then introduce "clustering with confidence," an automatic pruning procedure that assesses significance of splits in the cluster tree; the only user input is the desired confidence level.
