Spectral Phase Transition and Optimal PCA in Block-Structured Spiked Models Analysis
The author discusses the spectral properties of block-structured spiked models, aiming to find an optimal spectral method for inhomogeneous Wigner problems. The main thesis is that the proposed spectral method is optimal within iterative methods for these problems.
