Heat kernel and intrinsic Gaussian processes on manifolds

no code implementations25 Jun 2020 Ke Ye, Mu Niu, Pokman Cheung

In this work, we propose an intrinsic approach of constructing the Gaussian process on \if more \fi general manifolds \if {\color{red} in the matrix Lie groups} \fi such as orthogonal groups, unitary groups, Stiefel manifolds and Grassmannian manifolds.

Cohomology of Cryo-Electron Microscopy

no code implementations5 Apr 2016 Ke Ye, Lek-Heng Lim

The goal of cryo-electron microscopy (EM) is to reconstruct the 3-dimensional structure of a molecule from a collection of its 2-dimensional projected images.
