Optimal spectral method for inhomogeneous Wigner models.
统计
"Our results could also be used as spectral start [47] for the AMP algorithms of [48], making them optimal in terms of MMSE for these problems."
"The top eigenvalue of Dg(1)ΩK plays the role of the signal-to-noise ratio (SNR) for this block-structure spiked model."
