Characterization of the Basin of Convexity for Multi-Snapshot Spike Deconvolution via Variable Projection
Meghna Kalra, Maxime Ferreira Da Costa, Kiryung Lee
The problem of multi-snapshot spike deconvolution is studied, where the goal is to recover the locations of sparse impulses from their noisy convolution with a known point spread f…

Sparse Max-Affine Regression
Haitham Kanj, Seonho Kim, Kiryung Lee
This paper presents Sparse Gradient Descent as a solution for variable selection in convex piecewise linear regression, where the model is given as the maximum of -affine functi…
