Reconstructing Graph Signals from Noisy Dynamical Samples
Akram Aldroubi, Victor Bailey, Ilya Krishtal +2
We investigate the dynamical sampling space-time trade-off problem within a graph setting. Specifically, we derive necessary and sufficient conditions for space-time sampling that…

On Low-Rank Convex-Convex Quadratic Fractional Programming
Ilya Krishtal, Brendan Miller
We present an efficient algorithm for solving fractional programming problems whose objective functions are the ratio of a low-rank quadratic to a positive definite quadratic with…
