Recovering Quantized Data with Missing Information Using Bilinear Factorization and Augmented Lagrangian Method

Autor: Esmaeili, Ashkan, Behdin, Kayhan, Al-E-Mohammad, Sina, Marvasti, Farokh

In this paper, we propose a novel approach in order to recover a quantized matrix with missing information. We propose a regularized convex cost function composed of a log-likelihood term and a Trace norm term. The Bi-factorization approach and the A
