WebApr 14, 2024 · In this work, we focus on the general matrix sensing problem with linear measurements that are corrupted by random noise. We investigate the scenario where the search rank r is equal to the true rank r * of the unknown ground truth (the exact parametrized case), as well as the scenario where r is greater than r * (the … WebDec 28, 2014 · Robust Matrix Completion. Olga Klopp (MODAL'X, CREST), Karim Lounici, Alexandre B. Tsybakov (CREST) This paper considers the problem of recovery of a low-rank matrix in the situation when most of its entries are not observed and a fraction of observed entries are corrupted. The observations are noisy realizations of the sum of a low rank … good activities for adhd kids
