A Nesterov-style Accelerated Gradient Descent Algorithm for the Symmetric Eigenvalue Problem

Foivos Alimisis, Simon Vary, Bart Vandereycken

We develop an accelerated gradient descent algorithm on the Grassmann manifold to compute the subspace spanned by a number of leading eigenvectors of a symmetric positive semi-defi…

Low-rank plus sparse trajectory decomposition for direct exoplanet imaging

Simon Vary, Hazan Daglayan, Laurent Jacques +1

We propose a direct imaging method for the detection of exoplanets based on a combined low-rank plus structured sparse model. For this task, we develop a dictionary of possible eff…
