Spiked sample covariance matrices with possibly multiple bulk components

Xiucai Ding

In this paper, we study the convergent limits and rates of the eigenvalues and eigenvectors for spiked sample covariance matrices whose spectrum can have multiple bulk components.…

High dimensional deformed rectangular matrices with applications in matrix denoising

Xiucai Ding

We consider the recovery of a low rank $M \times N$ matrix $S$ from its noisy observation $S ~$ in two different regimes. Under the assumption that $M$ is comparable to $N$ ,…
