Signal Decomposition via Quadratic-Separable Optimization

L. Volpatti, B. Meyers, and S. Boyd

Manuscript, December 2022.

We consider the problem of decomposing a signal with missing entries into a sum of components, using the optimization formulation described by Meyers and Boyd. We propose a general form for the component loss functions, and an alternative algorithm based on quadratic-separable optimization. This yields a flexible and extensible method for formulating and solving signal decomposition problems.
