On the convergence of gradient descent for finding the Riemannian center of mass
We study the problem of finding the global Riemannian center of mass of a set of data points
on a Riemannian manifold. Specifically, we investigate the convergence of constant step …

Omnibus CLTs for Fréchet means and nonparametric inference on non-Euclidean spaces
Two central limit theorems for sample Fréchet means are derived, both significant for
nonparametric inference on non-Euclidean spaces. The first theorem encompasses and …

Strong laws of large numbers for generalizations of Fréchet mean sets
C Schötz - Statistics, 2022 - Taylor & Francis
A Fréchet mean of a random variable Y with values in a metric space (Q, d) is an element of
the metric space that minimizes q↦ E d (Y, q) 2. This minimizer may be non-unique. We …

Data analysis on nonstandard spaces
The task to write on data analysis on nonstandard spaces is quite substantial, with a huge
body of literature to cover, from parametric to nonparametrics, from shape spaces to …

Convex generalized Fr\'echet means in a metric tree
We are interested in measures of central tendency for a population on a network, which is
modeled by a metric tree. The location parameters that we study are generalized Fr\'echet …
