Finding Singular Features

no code implementations1 Jun 2016 Christopher Genovese, Marco Perone-Pacifico, Isabella Verdinelli, Larry Wasserman

We present a method for finding high density, low-dimensional structures in noisy point clouds.

The functional mean-shift algorithm for mode hunting and clustering in infinite dimensions

no code implementations6 Aug 2014 Mattia Ciollaro, Christopher Genovese, Jing Lei, Larry Wasserman

We introduce the functional mean-shift algorithm, an iterative algorithm for estimating the local modes of a surrogate density from functional data.

Estimating the distribution of Galaxy Morphologies on a continuous space

no code implementations29 Jun 2014 Giuseppe Vinci, Peter Freeman, Jeffrey Newman, Larry Wasserman, Christopher Genovese

The incredible variety of galaxy shapes cannot be summarized by human defined discrete classes of shapes without causing a possibly large loss of information.

Nonparametric Inference For Density Modes

no code implementations29 Dec 2013 Christopher Genovese, Marco Perone-Pacifico, Isabella Verdinelli, Larry Wasserman

We derive nonparametric confidence intervals for the eigenvalues of the Hessian at modes of a density estimate.
