Error Bound of Empirical $ℓ_{2}$ Risk Minimization for Noisy Standard and Generalized Phase Retrieval Problems

Junren Chen, Michael K. Ng

In this paper, we study the estimation performance of empirical $ℓ_{2}$ risk minimization (ERM) in noisy (standard) phase retrieval (NPR) given by $y_{k} = ∣ α_{k}^{*} x_{0} ∣^{2} + η_{k}$ , or noi…

High Dimensional Statistical Estimation under Uniformly Dithered One-bit Quantization

Junren Chen, Cheng-Long Wang, Michael K. Ng +1

In this paper, we propose a uniformly dithered 1-bit quantization scheme for high-dimensional statistical estimation. The scheme contains truncation, dithering, and quantization as…
