Tightness of the maximum likelihood semidefinite relaxation for angular synchronization
Afonso S. Bandeira, Nicolas Boumal, Amit Singer
Maximum likelihood estimation problems are, in general, intractable optimization problems. As a result, it is common to approximate the maximum likelihood estimator (MLE) using con…

Open problem: Tightness of maximum likelihood semidefinite relaxations
Afonso S. Bandeira, Yuehaw Khoo, Amit Singer
We have observed an interesting, yet unexplained, phenomenon: Semidefinite programming (SDP) based relaxations of maximum likelihood estimators (MLE) tend to be tight in recovery p…
