arXiv:2608.29868v2 Announce Type: replace-cross Abstract: We propose a differential step-down thresholding algorithm with randomized grid dithering for robust model order selection. It detects the value clustering of noise extrema. Our algorithm asymptotically achieves exact order recovery and prevents false alarms even under lowered detection thresholds.
