Corrected Block Sparse Spectral Optimization: Exact Models, Finite Identification, and Local Dynamics

arXiv:2610.25721v1 Announce Type: new Abstract: The block generalized-power method pairs threshold-based support selection with inexpensive Stiefel updates, but the standard block formulation conflates two nonequivalent objectives and leaves inactive components, threshold ties, and post-selection r…
