Depth separation for reduced deep networks in nonlinear model reduction: Distilling shock waves in nonlinear hyperbolic problems
Donsub Rim, Luca Venturi, Joan Bruna +1
Classical reduced models are low-rank approximations using a fixed basis designed to achieve dimensionality reduction of large-scale systems. In this work, we introduce reduced dee…

Manifold Approximations via Transported Subspaces: Model reduction for transport-dominated problems
Donsub Rim, Benjamin Peherstorfer, Kyle T. Mandli
This work presents a method for constructing online-efficient reduced models of large-scale systems governed by parametrized nonlinear scalar conservation laws. The solution manifo…

Exact and fast inversion of the approximate discrete Radon transform from partial data
Donsub Rim
We give an exact inversion formula for the approximate discrete Radon transform introduced in [Brady, SIAM J. Comput., 27(1), 107--119] that is of cost for a square 2…
