Characterization of the basin of convexity for multi-snapshot spike deconvolution via variable projection
arXiv:2607.09593v1 Announce Type: new Abstract: We study the problem of multi-snapshot spike deconvolution, where the goal is to recover the locations of sparse impulses from their noisy convolution with a known point spread function (PSF) across multiple snapshots. We adopt a variable-projection formulation that elimi
