Towards Optimal Estimation of Bivariate Isotonic Matrices with Unknown Permutations

Jun 25, 2018
Cheng Mao, Ashwin Pananjady, Martin J. Wainwright

* 46 pages, 1 figure. This paper is a longer version of the paper arXiv:1802.09963, v3 of which appeared in part as a 4-page extended abstract at Conference on Learning Theory (COLT) 2018. This paper studies the problem in another metric, and makes the appropriate corrections to Theorem 2 in v1 and v2 of arXiv:1802.09963, which was incorrect as stated and removed in v3
