Covariance Matrix Estimation for the Cryo-EM Heterogeneity Problem
Gene Katsevich, Alexander Katsevich, Amit Singer
In cryo-electron microscopy (cryo-EM), a microscope generates a top view of a sample of randomly-oriented copies of a molecule. The problem of single particle reconstruction (SPR)…

Spectral Convergence of the connection Laplacian from random samples
Amit Singer, Hau-tieng Wu
Spectral methods that are based on eigenvectors and eigenvalues of discrete graph Laplacians, such as Diffusion Maps and Laplacian Eigenmaps are often used for manifold learning an…
