CUR for Implicit Time Integration of Random Partial Differential Equations on Low-Rank Matrix Manifolds
Mohammad Hossein Naderi, Sara Akhavan, Hessam Babaee
Dynamical low-rank approximation allows for solving large-scale matrix differential equations (MDEs) with significantly fewer degrees of freedom and has been applied to a growing n…
