Fast Principal Component Analysis for Cryo-EM Images
Nicholas F. Marshall, Oscar Mickelin, Yunpeng Shi +1
Principal component analysis (PCA) plays an important role in the analysis of cryo-EM images for various tasks such as classification, denoising, compression, and ab-initio modelin…
On a linearization of quadratic Wasserstein distance
Philip Greengard, Jeremy G. Hoskins, Nicholas F. Marshall +1
This paper studies the problem of computing a linear approximation of quadratic Wasserstein distance . In particular, we compute an approximation of the negative homogeneous w…
Randomized mixed Hölder function approximation in higher-dimensions
Nicholas F. Marshall
The purpose of this paper is to extend the result of arXiv:1810.00823 to mixed Hölder functions on for all . In particular, we prove that by sampling an -mixe…
A Cheeger inequality for graphs based on a reflection principle
Edward Gelernt, Diana Halikias, Charles Kenney +1
Given a graph with a designated set of boundary vertices, we define a new notion of a Neumann Laplace operator on a graph using a reflection principle. We show that the first eigen…
